The past week was great for Astronomy and Astrophotographers in the CNY area. Seven straight days of clear nights around the new moon. When was the last time that happened?
The first night out was Tuesday 11/2/2021. My plan that night was to shoot the Helix Nebula, however my camera a Sony A660 Mirrorless was not cooperating with Astrophotography Tool (APT). I could have certainly photographed the Helix nebula however as I discussed in the last post I have been using plate solving to center the image. The issue with the camera was that the orientation sensor which senses when the camera is vertical instead of horizontal was causing the images to be doubled and not display correctly in APT. This meant plate solving wasn't possible. Unfortunately I didn't realize this until I got home (I eventually found the true solution, and there is more on that below.) As a back up plan I photographed the Bubble Nebula (NGC-7635) in Cassiopeia. This is twenty nine 200 second guided subs taken at Darling Hill Observatory in Vesper, NY. Using a Sony A6600 camera on a iOptron CEM40G mount using a Celestron 127 Mak Telescope.
