Ovo je jos jedna stavka koja je nuzna za kvalitetnije snimanje. Obzirom da mi dosta uradaka bude defokusirano, odlucio sam se izraditi autofokuser. Odlucio sam se za remenski prijenos buduci da zupcanici stvaraju backlash. Redukcija je 1:3. Od Outtee sam dobio arduino plocice sa procesorom i driverom. Stepper je NEMA14 bipolarni 1.8°/step. Dao mi je i GT2 remen i remenice, no uzeo sam u njega prekratak remen. U međuvremenu su mi nakon dugog cekanja stigle mxl remenice i remen sa eBaya pa sam stavio njih. Skalamerija se spaja na osovinu fokusera fleksibilnom spojkom. Osovina na vecoj remenici je 8mm i ima dva mala kuglicna lezaja koji su ostali nakon kupnje novih za puzne vijke na montazi. To sam stavio u kuciste za lezajeve i namontirao na alu L profil. Na drugoj stranici L profila dolazi elektronika. Na fokuser se profil pricvrscuje preko prstena sa nosacem koji jos moram napraviti. Ovo ce biti za astrograf i ED80. Za ED127 ce biti malo drugaciji nosac.

E sad ne znam hoce li biti problema spojiti Onstep na APT preko ascoma.

Zasad je to to. Danas bi trebao sve sloziti i upogoniti da vidim sljaka li.

Evo par slikica :-)

Mislim da nebi trebala biti drama spojiti preko ascoma u apt

Evo slozio sam skalameriju i spojio se preko bluetootha na mobitel u Onstep controller. Sve radi. Morao sam na driveru postelovati potenciometar za smanjiti struju da se motor previse ne grije. Driver se ne grije. Ne znam da li bi mozda trebao staviti motor manjeg otpora da se ne grije.

Evo slika! *hopla*

Evo video upravljanja iz APT-a. Sad je sve spremno, samo jos podesiti da fokusira, samo ne znam jel to radi nakon nekog broja slika ili nakon drasticnijeg gubitka fokusa... *jok*

Radit ce vise ekspozicija za redom i mjeriti zvijezde. Neznam na koji nacin funkcionira APT, ali u NINA je bitno da ti step size, tj. pomak izmedju koraka ne bude veci od CFZ ( critical focus zone). Neznam koje postavke sve APT ima.
U NINA imas opcije da stavis da ti fokusira nakon nekog vremena, nakon odredenog pada temperature, kod svake promjene filtera, itd.

Dobro, ja snimam osc kamerom pa nemam izmjenu filtera. No samo me zanimaju najvise ti intervali jer sam bio na apt stranici i nisam nasao nista o tome.

Pod intervale mislis koliko cesto trebas raditi autofocus u toku snimanja?
Ovisi o padu temperature. Ja osobno kad snimam, slazem da mi ekspozicije po filteru traju max 45min i onda autofocus kod promjene filtera. U tvojem slucaju stavis vrememski period 45min i vozi.

S tim da sam primjetio da se fokus najbrze mijenja u pocetku kad se teleskop tek iznese iz toplog auta. Poslije sve sporije. Nekidan, kad smo bili u Gustirni Mladen i ja, od negdje ponoc i pol pa skoro do jutra fokus se nije mijenjao skoro nista, provjeravao sam i nisam primjetio osjetnu promjenu.
