IC1805 - The Heart Nebula
Fri Nov 24 2023
Happy Thanksgiving! It was clear again last night and I decided to switch gears and try to get my wide-field setup going. I haven’t had a ton of success getting my C8 back focus perfected but I want to use this setup a lot this winter so I figured I’d try it out and it’s not perfect but not too far away from it.
