Subject: Re: CCD kamera
Nedavno jsem se na konferenci seznamila s clovekem, ktery zalozil ve
Francii skupinu lidi zabyvajici se stavbou a pozorovanim s CCD. V soucasne
dobe je v ni nekolik set lidi a kamer na cipu KAF-400 (to je v ST-7) postavili
nekolik desitek. Jak kamera vypada - presna dokumentace je na
http://astroccd.com/terre/audine/
Nekteri mi pratele astronomove amateri projevili zajem o takovou kameru,
protoze jeji cena by se pohybovala v tisicich (mozna neco pres 10 tis.)
Kc, podle toho, co budeme schopni v Cechach si udelat.
Asi pred tydnem mi muj francouzsky kolega sdelil, ze Kodak porada v zari
reklamni kampan na ty cipy KAF-400, prodava je za 80 dolaru, coz je cena
asi 4.5x nizsi nez normalne. Chceme tedy nejake koupit, pro maly pocet
lidi, kteri o tom tady vsak vedi (zatim chceme dva, mozna tri cipy) je
vsak asi problem, aby se ta firma s nami bavila, takze Francouzi pro nas
nejake cipy objednaji. Proto zkoumam, jestli by o stavbu kamery nemeli
zajem jeste dalsi lide, je to jedinecna moznost, jak cip ziskat a da se na
tom usetrit par tisic. Je to vsak trochu nejisty podnik, nikdo v Cechach
nema zkusenosti se stavbou a jejich systemem, i kdyz pry je to snadne nebo
nam muzou kameru kompletovat primo Francouzi. Da se u nich koupit souprava
potrebnych elektronickych soucastek kompletni testovana (asi $200) nebo
jen karty s obvody a udelat si to tady (<$100). Zatim vim o dvou lidech,
kteri by to chteli stavet a tvari se jako ze by to nemel byt problem,
jednoho znam dost dobre, zabyva se opravami i takovych veci jako digitalni
fotaky. Mohl by snad umet delat i servis techto kamer.
Jak je to se zarukami asi moc jasne neni, proto nevim, jak se takova vec
hodi pro hvezdarny. Je to pro duse dobrodruzne. Kdyby se podarilo tady ty
dve kamery postavit, mohli bychom dal delat dalsi pro hvezdarny za
nekolikrat nizsi cenu nez jsou komercni a navic by byl cesky servis, mam
proto velky zajem, aby se tato akce podarila. Pro zacatek je to vsak
riziko podnikani. Jak v pripade uspechu ziskavat dalsi cipy to nevim, asi
normalne za 350 dolaru, pokud by se takovych objednavek seslo vic. Protoze
si nejsme jisti s odbytem a uspechem, bojime se koupit mnoho cipu, abychom
kamery rovnou delali a pak prodavali. Spis to pro zacatek vidime jako
zprostredkujeme soucastky nebo si sezente jak chcete, a nekdo z tech
techniku ve Francii nebo tady vam to udela.

You mean the Lenkamobile...
I would
like to see Saturn in larger telescope, I haven't seen for a long time.
It always make me feel better. It is much more efficient than music to
calm me down. I have had the workshop of the observatory modify the
eyepiece holder so that I can use mine instead of the old ones from the
dome, and the images are much better. We have also found that using a
wratten filter removes all the glare from the chromatic aberration.

Yes. We just finished a "moon walk", going from procellarum to
Copernicus, then to Fra Maurao (Apollo 14).
By the way, forgot to tell you. Kodak has a special sale in September,
and since they have their new 'E' type CCDs, they are selling the
regular ones at prices I didn't believe. The grade 1 KAF400 is around 80
dollars, which is very cheap. Moreover, the KAF1600 is now only 450
dollars, this is very very cheap. I don't know if you can pass along
this information to your amateur friends so that they contact Kodak in
your country. Otherwise, we (i.e. aude) are going to try to make a group
purchase here and will let you know (apparently they only wanted to sell
to companies, but groups are OK, at least here in France). Have them buy
the CCD now, we know how to make the camera around it and they can do it
later.
They are still making some shots of the outside, and maybe I can go to
bed. My daughter is going to wake me up early I believe...

Tak prehledne a pomalu. Nebudeme otravovat Mauryho, podarilo se mi
tyto veci v podstate zjistit na www, snad je to duveryhodne.
SBIG pouziva pro kamery ST-7 standardne Class1, pro ST-8 Class2, ostatni
se musi specifikovat. Prave na tyto defaultni se vztahuji ty slevy, takze
nejde o zadnou horsi kvalitu (mozna jsi ale myslel neco jineho). Class1
znamena, ze na celem CCD muze byt az 5 pixelu spatnych (ve stredni casti
jen dva), zadne skupinove ani sloupcove defekty. Normalni cena KAF400 (i
L, C, 401, 401L= i ty antiblooming, nejaky color a to 401 je taky nejaky
maly rozdil) je pro Class1 tech 350$, na co ted maji reklamni slevu za
80$. Neni to tedy vyprodej spatnych cipu, ale akce na podporu prodeje.
Mimochodem, Class0 (uplne bez defektu, a ted i bez slevy) stoji 550$.
Normalne stoji nejhorsi trida 3 (Eng. grade) 100$, tam uz muzou byt i
nekolik sloupcovych defektu. Takze opravdu nejde o nic horsiho. Ja vim, ze
ta sleva je tak sokujici, ze se ani nechce verit, ze by to melo byt dobre.
http://www.sbig.com/sbwhtmls/online.htm
Druha vec, kde jsem se zminila o nejake horsi kvalite, jsem koukala ze je
o tom anti-bloomingu(ABG, AntiBlooming Gates). Vyhoda toho, ze nevytekaji
vertikalni ocasky z jasnych preexponovanych hvezd, je vykoupena nizsi
citlivosti a rozlisenim. Mezi pixely se udela jakasi mezera, ktera zabere
asi 30% plochy pixelu, tim se snizi citlivost a hloubka potencialove jamy,
proto se musi 2x prodlouzit expozice, aby se dosahlo stejne urovne. Navic
ty mezery trochu zhorsi rozliseni. Zalezi na tom, o co Ti tedy v
pozorovani jde. Myslim, ze kdyz chceme dosahnout co nejvyssi citlivosti a
rozliseni, je lepsi non antiblooming. Problem tam muze nastat jen tehdy,
kdyz chces merit neco, co je blizko jasne hvezdy a dostane se do toho
ocasku, to se pak musi kratit expozice. Nebo treba delat hezke obrazky
hvezdokup.
http://www.apogee-ccd.com/ccd102.html
Co mi vsak neni moc jasne je to, ze SW umoznuje jakesi nastaveni ABG/NABG,
low, medium, high a podobne, tak nevim, jestli u tech ABG cipu se to da
jako menit, a nebo si clovek proste musi nakonfigurovat podle toho, co ma.
V popisu cipu je psano "antiblooming optional", coz nevim, jestli mysli
jako ze si muzeme vybrat druh nebo to SW nastavit. Podle vysvetleni CCD
university mi to vsak pripada jako HW zalezitost. Takze na to bych se
pripadne Alaina zeptala, jestli se mi nepodari zjistit. V kazdem pripade
my mame nastavene v ridicim programu ke kamere No ABG nebo ve starsim k
ST-6 low.

To je riziko u vseho, co si koupis a nepostavis. I kdybys koupil hotovou
ST-7 za nejakych 150 tis Kc, kdyz nebude fungovat, musis na nadrazi... Jak
se domahat oprav u Francouzu, to je treba zjistit, ale aspon jsou bliz.
Mozna se tady ale nabizi vyhledove moznost, ze by servis mohl delat Petr
Vaca, kteremu taky tento mail forwarduji. Ma zajem naucit se stavet
kamery, chce taky koupit NABG KAF400 cip a kdyby se ukazalo, ze mu to
pujde dobre, mohl by Ti ji treba i udelat. Zalezi na tom, kdy se Ti podari
dat dohromady ten dalekohled. Jinak u Francouzu jsem to pochopila tak, ze
muzou dodat hotovou kameru (pripadne ze soucastek, ktere jim das, aspon
ten cip), to jen pokud se chce podstatne usetrit, da se neco udelat doma.

V nedeli jsem byla navstivit jednoho kamarada, zkuseneho fotografa a
elektronika v Kladne. Jmenuje se Lojza Garamszegi, pres fotaky a
promitacky a videa se dnes propracoval i k takovym vecem jako jsou
digitalni fotaky a videokamery. Ma skvele vybavenou dilnu a zda se, ze to
opravdu umi opravovat (jinak by se asi neuzivil). Nase CCD kamery ho velmi
zaujaly, i kdyz asi ne tak, aby byl ochoten do toho primo investovat,
nakoupit soucastky a postavit. Kdyz mu to ale nekdo da, myslim ze to rad
postavi a verim ze i dost spolehlive. Dala jsem mu www adresu te Audine
kamery, ukazala jsem nejake obrazky a libilo se mu to, ze by se podle toho
to melo dat udelat.
Dnes se vratil na internet taky Alain Maury, na kterem to vsechno visi.
Musime na nej byt hodni a hyckat ho. Ja to asi delam dost spatne, protoze
mi prave kopiruje CDs s nejakou hudbou od Phila Glasse, snad ho to ale
neodradi od nasi zatim jednostranne spoluprace (on nam neco hezkeho
poskytne a my mu nic nedame). Krome nejnovejsich zazitku z kina z nej
vypadl taky popis jeho pristupu k stavbe kamery:

L:> Really? Maybe it is not necessary to be so worry.

A: Yep. A few screws here and there and there it is. If you solder all the
boards yourself, maybe two evenings, but not more.
Pro nej je to tedy hracka na jeden, nejvys dva vecery (pokud se to cele
paji). Takze mozna je cas myslet i na to, co dal. Jestli jsem to dobre
pochopila, je mozne si u nich koupit celou sadu soucastek, z ktere se to
da poskladat. Kdyz to nebudeme chtit skladat my, udelaji to oni (nebo
primo on?), ale pak to vidim, ze by to asi melo byt drazsi, preci jen
jejich cas je drazsi. A taky by to byla zase cerna skrinka. Na druhou
stranu by melo byt pomerne jistejsi, ze to bude fungovat. Dale se tu
nabizi jako jine reseni aktivni spoluprace s Lojzou, ja preci jen neumim
posoudit, jak je to pajeni nebezpecne, pajela jsem jen konektory a dratky
na dalekohledu a neco v aute, zadne plosne obvody ci co. Tak jeste cekam
na odpoved na otazku kolem toho rizika poskozeni. Dalsi vec je ovladaci
program. Na strance
http://astroccd.com/terre/audine/pisco/index.htm
se da stahnout a asi je to vyresene. Me osobne by vsak zajimalo docela
udelat si vlastni program podle zdrojaku, ktere tam taky nabizeji. Nevim,
co vsechno ty jejich umi, jednou jsem si to zkousela instalovat a ono to
na me hazelo hlasky s vykricnikama francouzsky. Jde o to, aby program umel
treba delat automaticke serie snimku a pripadne umel casem ridit i filtry.
Me to zajima, protoze to asi brzy budeme resit s jinou kamerou tady v
Ondrejove, ale je dobre se nekde ucit. Docela zacinam uvazovat, jestli
bych si taky neporidila soucastky a dala postavit kameru na SW
experimenty a az bych se to naucila, nekomu bych ji strelila. To uz jsou
ale detaily, ktere se vas moc zatim netykaji.
Zajimalo by me tedy jak kompletni vybaveni byste si prali. Pozeptala bych
se pak to presnych cenach, podle mailu asi 2 mesice stareho se veci maji
takto, ze elektronika cela postavena a testovana by prisla zhruba na $200
a kdyz sezenete elektronicke soucastky, ty karty s obvody by prisly na
mene nez $100. Jak ostatni veci - zdroj, chlazeni, skrinka - to zatim
nevim.
Dnes behem dne doufame ze bude jasne, jak se udela ten nakup, vratil se z
dovolene clovek, ktery by to mohl zprostredkovat. Nas se to ale asi az
tak netyka, podstatne bude jen komu kdy co zaplatit. Pokud trvate na tom,
ze oba chcete kazdy jeden non-ABG (ty citlivejsi) KAF-400, nemusite ted
dal nic resit.

Ahoj vsichni,
konecne se mi ozval Alain s novymi informacemi o jednani s Kodakem i
stavbe kamery. Vse je v prilozenem mailu.
Pokud nekdo mate mezinarodni visa kartu, muze objednat cipy primo u
Kodaku, jinak asi nezbyva nez se spolehnout na Francouze. Uz vedi, kdo tu
skupinovou objednavku udela, jen nemam termin. Prosim co nejdriv, jestli
nekdo nemate nebo nevite o nekom, kdo by tu kartu mel a byl ochoten
zprostredkovat, abychom byli nezavisli, ja zatim nikoho takoveho neznam,
ale budu se ptat.
Shrnuti cesky k te stavbe:
Ostatni casti krome elektroniky se daji taky objednat u te jejich firmy.
Ceny jsou na webu, i s obrazky tech soucastek.
http://astroccd.com/terre/audine/prix.htm
Ceny te elektroniky jsou jak jsem driv psala, co to presne zahrnuje bude
lepsi jeste overit na te strance. Mechanicke casti jsou jeste dalsich 300
dolaru, ale podle planu, ktere davaji, by se mohlo dat sehnat nebo udelat
u nas levneji.
Kamera, kterou delaji, neobsahuje zaverku, coz se pry hodi. Navrhuje
udelat vetsi hlavu kamery z nejakeho video zarizeni (nevim, co je
camcorder, Lojzo...) kde je nejaka clona. On takovy system ma, tak by snad
pripadne dal poradil.
Zniceni cipu behem stavby pry neni snad prilis pravdepodobne, jim se to
zatim nepodarilo (uz toho postavili zhruha 70). Testuje se bez cipu a pak
uz se tomu nic nestane.
Toz tak zatim asi vse, vyjadrete se prosim i k tomuto, ale to uz nespecha.
Ja bych si predstavovala, ze technici si muzou zkusit pohrat pokud mozno
co nejvic s nasimi soucastkami, jestli se podari udelat kameru co nejvic
"ceskou", a astronomove se zaridi podle jejich vysledku. V nejhorsim si
proste na svem cipu nechaji udelat tu francouzskou Audine, ktera by mohla
vyjit na dalsich asi 500 dolaru.

Yes, it is sold by that company, I think the prices are in the web
pages.

Yes. The first price includes the printed circuit boards, with surface
mount chips already soldered, but no other electronic components. It
includes a CDROM which is the technical description, construction manual
and so on and a cable. Its price is 445 francs, and currently to give
you an idea of the price, 630 francs=100$.
For 1270 francs, or about 200$, you get the complete electronic kit, not
built (the above kit plus all the electronic parts).
The mechanical kit is 1850 francs, or about 300$. But since the plans
are available, it is very likely you can build it if you have a machine
shop for a better price.
Also since the camera does not contain a shutter it is a good thing to
find a shutter, and build a larger camera head to include the shutter.
You can try to locate a video equipement repair company, and get a dead
optical bloc for a camcorder. In it, there is a diaphragm which can be
used as a shutter. Works very well. I have such a system on my own
KAF400 based camera (which is not an audine).

Everything can be done easily of you goof. None of the builders of
audine camera (about 70 by now) has reported frying its chip. Usually
you test everything without the chip, then you install the chip once and
for all.
By the way, the audine site should be translated in english before the
end of the year.

S visa kartou by to bylo mnohem jednodussi a nezavislejsi. Snad se nam
to podari tak udelat, mam uz neco rozjednane.
Zaverky k tomu svemu systemu Audine nedavaji, protoze jedina rozumna
co se da sehnat je velmi draha a da se fotit i bez toho. Dela to ocasky
za jasnymi hvezdami (jine nez blooming), da se to odstranit pomoci jejich
SW, ale pro narocnejsi je mnohem lepsi mit zaverku. Alain navstivil mistni
video opravnu, kde dostal zadarmo nejaky stary opticky blok z videa ci co
je to ten camcorder, pridal tranzistor a par dratu a hezky to funguje.

I will let you know when the people from aude make their purchase

I think that if you find somebody with the visa card, it is easier, and

Because a while ago, the only shutter one could find was made by
uniblitz and costed like 1500 francs (or 250 dollars), and it was quite
expensive. The shutter is very useful to make exposure. If you don't use
a shutter and make an exposure with a bright star in it, there will be a
trail left bahind the star on the image. There is a correction function
for this effect in the PISCO software, but it is much better to have a
shutter, and clean images.

Yep, but it is so much better when there is one. If you contact a video
equipement repair shop in your country (I called the local Sony shop),
they will very likely let you have old optical blocs of camcorders, and
you get free shutters. You need to add a single transistor and a couple
of wiring to have it working.

Soucasny stav kolem kupovani cipu. Kdyz bude nejhur, prevod muze
zprostredkovat jeden z dvou kolegu meho taty, kteri maji visa. Tak je
pravdepodobne, ze cipy nam bude kupovat japonska operni zpevacka, nebo
solista Narodniho divadla...

zbezne prohledl Milan Wudia, borec pres CCD a vubec elekroniku, ktery uz
taky kdysi jednoduchou CCD kameru postavil, ma do toho chut dal, ale jak
uz to u tak skvelych lidi byva, nema moc cas. To reseni se mu vsak velmi
libilo, ze je podoba jeho reseni, jednoduche a pokrokove, melo by byt
spolehlive (navic vyzkousene) a takto chape, ze by se to melo dat postavit
za dva vecery. Laka ho dat dohromady zkusenosti Francouzu a doplnit ci
prizpusobit nasim podminkam (ze i s tou zaverkou pry neni zadny problem),
protoze by mohla vzniknout velmi levna a dobra kamera, dostupna dokonce z
nasich zdroju. Hlavni problem, ktery mel, ze se do toho nepustil driv sam,
byla nedostupnost cipu, ktera se ted snad podari vyresit a pozdeji by
mohla byt sance v te spolupraci s Francii, kde obcas nakoupi hromadku
netestovanych cipu za par supu, otestuji a roztridi, nejhorsi na pokusy,
nejlepsi treba na fotometrii. Nebo budou treba upgradovat.
Je mozne, ze budu mit brzy jeste lepsi a konkretnejsi zpravu, ale to je
zatim tajne...
Podle vseho to skoro vypada, ze ten napad postavit si kameru neni az tak

Nakonec jedna neurcita zprava. Nedalo mi to a napsala jsem Kodakum.

kolem cipu a CCD kamer, a co je nejpodstatnejsi - uz si sam postavil
takovou kameru na cipu podobnemu tomu v ST-6. Jak mu to funguje muzete
videt na http://www.mii.cz/people/pc/index.htm. Mame tedy mezi sebou
opravdoveho odbornika. A cloveka, ktereho jsem asi jeste nikdy nevidela.
Uz jsme na tom vsichni stejne, s nekterymi se zname jen z mailu. Mozna by
byla docela legrace se nekdy sejit zive. Jen jsme z ponekud velke plochy.
Pavel se svymi prateli uvazoval i o stavbe kamery na KAF cipech, ale blue
enhanced. Upozornil me, ze kvantova ucinnost (neco jako citlivost) u E
verzi kodaku je ve viditelne oblasti az 2x vetsi nez u normalnich verzi,
takze enhanced by mely znamenat dost podstatne zlepseni vysledku. U TC
cipu v ST-6 je kvantova ucinnost i u normalnich verzi dost vysoka a neni
to tak zle ani v te modre casti, asi jako u E verzi KAF, ale hlavni
problem je mnohem vyssi sum. Coz by odpovidalo tomu, ze nase enhanced ST-6
nebyla velkym pokrokem, ale u KAF je to jine, protoze maji velmi nizky
sum. Podrobne povidani o srovnani najdete na
http://www.sbig.com/sbwhtmls/blue_enhanced.htm. Pozor, je tam hodne
obrazku.
Takze je mozne mit jeste o kus lepsi kameru, ale cena je pak mnohem vyssi.
Na druhou stranu, da se zacit s temiho normalnimi KAF, vyzkouset, naucit
se, pricemz upgrade na enhanced by pozdeji nemel byt problem. Treba si
kodaky vymysli zase neco noveho a budou je prodavat za 50 dolaru. Nebo
pujde koupit pouzity od nekoho, kdo bude upgradovat na KAF1600. Presto
kdybyste nekdo chtel rovnou E, nechte si to projit hlavou a dejte mi vcas
vedet.
Zdravi Lenka

Ahoj vsichni,
dostali jsme mail od Kodaka, potvrzuje, ze nam to posle do CZ! Takze uz
jen se rozmyslet, kolik toho kdo opravdu chceme, a kdo a jak konkretne
udela ten prevod. Prachy dam dohromady (pokud by to slo pres moje okoli) a
pak si to nejak vyridime. Jen aby se to vcas kontaktovalo, proto uz bych
nase snazeni smerovala k cili. Nemam presnou predstavu, jak dlouho to
placeni trva, ale nejpozdeji v pondeli odpoledne pristi tyden bych to
radeji mela pripravene. Jestli nekdo vite, jak se provadi a jak dlouho
trva placeni, dejte mi prosim vedet, nevim, kdy se mi podari mluvit s temi
zpevaky. Jsou v jednani jeste dalsi moznosti toho placeni a doruceni do
CR, ale to zatim nevim, takze pro jistotu pocitam zatim s touto cestou.
Zdravi Lenka

Dear Jeffrey,
I would like to ask you about the possibility to purchase KAF-401 chips
you offer. We need only about 10 chips for the Czech Republic now and we
should be able to use a visa card to pay. Can we communicate directly with
you?
Best regards,

Kodaku zrejme dosly slibene KAF cipy
grad 1, a tak dava misto toho grad 0 - tedy ty dokonale! Normalne stoji
pres 500 dolaru. Treba budeme mit taky stesti. To byste pak meli
kvalitnejsi cipy nez se davaji do standardni ST-7.

Me too. Have seen emails were people were happily surprised by the fact
that Kodak had sent them a grade 0 chip instead of a grade 1, since they
seem to be out of grade 1. This is good news. Grade 0 are basically
perfect devices.

Vite uz, ze v poledne bylo deadline pro objednavku cipu. Seznam lidi, kdo
co chce jsem poslala Pavlu Cagasovi, ktery to dal doplnil a predal Jozkovi
Chlachulovi tc. v USA. Jozka se pokusi cipy pro vsechny koupit, doufejme,
ze bude mit dost penez, protoze na posledni chvili projevili zajem dalsi
lide. Cipy by mel Kodak poslat nejspis Pavlovi, budeme pak muset zaplatit
navic to DPH, jak jsem varovala, a clo. V jake mene, kdy a jak se bude
platit tedy ted zavisi hlavne na techto dvou, pujde to tedy nakonec mimo
me a nemam k tomu v teto chvili zadne dalsi informace.
Nekteri uz zkoumaji schemata a premysleji, kde sehnat informace, ktere
jeste nemaji. Jde o to, ze kdo tu kamery stavel po svem, vetsinou
potvrdil, ze francouzske reseni je velmi dobre a je skoda vymyslet to
podobne nezavisle. Pritom vetsinou technici maji zajem delat kameru
kompletne z nasich soucastek, jestli jsem to dobre pochopila. Na www maji
Francouzi podrobne mnoho veci, ale neni schema plosnych spoju a nekolik z
vas uz melo dotaz, jak to sehnat. Podle zkusenosti Pavla Kubicka, ktery s
Francouzi uz o tom kdysi jednal, nechteji autori jen tak schema dat, ale
nejakych 30 dolaru by to spravilo. Jina moznost je si od nich ty plosnaky
koupit a okouknout, bylo by to drazsi, ale mozna spolehlivejsi. Tak se
rozhodnete, jakou variantu zvolit a jak na to vzit penize.
Alain Maury mi prozradil tajnou adresu, kde si vsechny ty francouzske
stranky muzete precist anglicky, je to sice jen automaticky preklad, misty
velmi legracni, pro vetsinu z nas to ale bude asi prijatelnejsi nez ta
francouzstina. Vyslovene nezakazal tu adresu sirit, a kdyz jsem se ho
ptala, neodpovedel mi, jestli mu to vadi, tak predpokladam, ze je mu to
ukradene (ma ostatne mnohem horsi starosti, tak se nedivim). Proc je
zrovna tento clovek pro me tak zajimavy? Krome jineho zalozil pred
nekolika lety ve Francii aktivitu asi dost podobnou te nasi a vysledkem je
nejen jejich skvela kamera, ale i mnoho desitek aktivnich CCD pozorovatelu
a nekteri z nich jsou opravdu vynikajici, takze se zapojuji do prace po
boku profesionalu. Pritom jejich dalekohledy nejsou prilis velke,
mnozi mate mnohem vetsi. Mela jsem tu cest s nekterymi z nich trochu
spolupracovat pred nekolika lety a jejich jmena se casto vyskytuji v
planetkovych cirkularich (ostatni obory moc nesleduji, tak nevim). Krome
spousty legrace tedy delaji velmi uzitecnou praci, a z velke casti je to
rozvinute a zprostredkovane Alainem. I v soucasne dobe, kdy se bourlive
jedna o zmenach v organizaci pozorovani a databazi v Minor Planet Centre,
Alain jako profesional zastupuje zajmy amateru, aby dal se mohli co
nejlepe delit o zajimavou praci s profesionaly na vyzkumu planetek.
Astronomie je ted uz velmi mezinarodni, takze haji i vase zajmy a to, ze
rozjizdime akci s kamerami spolecne, bylo taky vyprovokovane jeho zminkou
o sleve a nabidkou pomoci nam, kdyz si nepomuzeme sami.
