Photography of Nebulas in Dark Sky
August 11th, 2008
This photo was a surprise to me. I will show a 3 color version (Ha,Hb,OIII) soon. Wide angle is the key.
- The galaxies need dark skies but I will try to find the practical limit.
- Exposure time: 10 min
Optics: f/1.8 85 mm Nikkor lens MF
CCD: DSI3 pro (cooled to 32 F)
Filter: Ha Baader 7nm
Platform: LX200GPS (no guiding)
FOV ~ 7 degrees
