Description

As I mentioned in my last image, I'm still struggling with astigmatism when using this scope so the corners look a little wonky. I'm hoping it's just that my spacing is a little off and that there's nothing inherently wrong with the scope. I'll be taking it down and remeasuring everything again this coming week. Here's hoping I'll finally be able to solve this issue! I also need to work on my sub duration. With heavy star fields, a faster focal ratio and the wider bandpass of the Baader Highspeed Narrowband filters, I think 5 minutes is simply too long - at least with this camera.

Special thanks to Noodle, Alberto Ibañez and Kevin Morefield for helping me figure out how to use Starnet++ without leaving artifacts behind.
