Pitanjce!

Buduci da nisam uspio nabaviti Meade 10" SCT, razmisljam mozda dogodine rijesiti jedan od kineskih modela 250mm f4 newtona za deep sky po principu kao sto sada snimam sa 150mm f4, buduci da bi ova homemade strain wave montaza mogla primiti toliku cijev.

E sad me zanima redoslijed! Ako zelim simulirati fokalnu kao na RC-u (2x barlow, f8) za male planetarke, da li bih morao koristiti specificni barlow koji ne bi unosio greske na rubovima? Da li bi ga morao koristiti zajedno sa koma korektorom i kako bi to uopce trebalo ici?

i ja sam razmišljao o takvim egzibicijama.
Dakle sa Barlowom ćeš imati duplo manje vidno polje, one najgore rubne greške ćeš izbjeći.
Mislim da se koristi bez CC.
Ali pošto biš snimao male planetarke niti ne treba te brinuti šta je na rubu, cropaj.

Treba utvrditi da li barlow unosi kakve devijacije po rubu ako bih ga koristio skupa sa koma korektorom? Kako se barlow ponasa bez koma korektora? Da li postoje specijalni barlowi za snimanje koji su korigirani po rubu? Za ovu svrhu bih isao sa 2" 2x barlowom. Akromatski barlow na newtonu mi ne stvara neku pretjeranu kromatsku aberaciju, jedino je pitanje ruba polja.

Imam doma neki 2" 2x ED barlow. Nasarafit cu ga na Maxfield koma korektor i sve to u astrograf pa cu probati okinuti par probnih frejmova.

Paracorr trpi Barlow, a i fino si ignorirao onaj APM Barlow s ugrađenim koma korektorom koji sam poslao.  *zubo*

Ah sad vidim, pardon *he*

Malo sam/nisam pratio dok sam na poslu bio.

No probat cu najprije ovu kombinaciju veceras, korektor + barlow, obzirom da to imam pa ako uspije da ne kupujem bezveze.

Da, meni je jako malo polje sa 533C kamerom pa se vidi svega nekoliko zvijezda... :-(

Sad znam da nema smisla barlowirati newtona, vec kad si rijesim 250-tku, snimati preko koma korektora kao i dosad pa croppati zeljeni dio gdje je neka manja maglica.

Radiš guding? Da savršeno poklopiš guider scope s glavnom cijevkom, pa radiš platesolving s guding kamerom?

Da, znam. Ali nisam bio spojen na internet, vec mi je laptop bio spojen na montazu preko wifi-ja. To mi treba da mogu u slucaju potrebe za postavkama struje motora, brzine slewinga i microsteppinga nesto mijenjati po potrebi. Onstep nema sucelje kao sto Skywatcher ima EQmod. Ovdje je sve preko browsera, tako da laptop mora biti spojen na wifi od montaze. Je*iga, SW i Onstep se razlikuju, tako da uvijek bude nekih caka na koje treba paziti inace si u gabuli, narocito kad nesto krene stekat na terenu.
