Day 1378 #DailyPhoto #SkyWatch #Astrophotography Last night's #FullMoon taken with my new-to-me ZWO 533mc Pro camera controlled by my #ASIAir minicomputer. The video shows the atmospheric instability that makes sharp focus challenging. I decomposed the video into individual frames to stack into a photo but the lossy compression of the MP4 made stacking problematic. Next time I'll use AVI. I was also surprised that I couldn't get the entire full moon in the 1 inch square sensor of the camera with my 250mm lens. Creating the video was an excellent #StillLearning experience. This is one over-sharpened frame from the video.
The other outer board from the memory unit - I believe the "sense amplifiers" that read the data from the array sense lines.
