The craziest thing happened to me a few days ago, I won an APOD for my Messier Catalog 🎉
What's special about it is that all the objects are shown at the same magnification, so the same size as seen from Earth.
I started astrophotography last summer with a 349$ Seestar S30 smart telescope, and quickly started to collect Messier object images. I then wrote a software to place them on a grid to keep track of the progress and have a nice visual in the end.
I spent a crazy amount of time processing the images and restarted from scratch half way through to have a processing as similar as possible between the targets, especially for the background color.
I finally completed recently with over 160h of integration in total! Each small square is 600x600px of the native Seestar S30 resolution for a total of 7200x7200px.
