This is my first attempt with a Newtonian telescope (I showed the telescope off in my previous video). Today’s target was the Pacman nebula. This telescope has a focal length of 750mm compared to over 1200mm with my SCT, so now larger objects may fit a little better in the picture. But learning to collimate was way harder than I thought it would be. Tonight, I could only get in 35 minutes of exposure time before the clouds rolled in – ruining my chances at a color image.
