Description

I've been revisited some Python code to acquire image data with and had a few hours of testing last night. I also went back to using INDI for my driver subsystem as I much prefer working in the Linux environment when possible.

Background was more chunky than usual which might be from not using a large enough dither offset. But the Canon 200mm lens is still a joy to work with and gives such nice large FOV and good tight stars @ f/3.3.
