I decided to make a composite of some of my favorite photographs from this last year. Although I've shot around 90 different images, most of them are some of the more "boring" star clusters. I'm hoping to finish up photographing the entire [Messier Catalog](
https://en.wikipedia.org/wiki/Messier_object) by next summer, as [I only have ~15 objects left to shoot](
https://i.imgur.com/XnTBVNU.png). The 8 images in this composite represent **156.1 hours of total exposure time**, most of which has been from the roof of my light polluted apartment. According to my spreadsheet I have close to 370 hours of total exposure time across all of my images for 2019. Getting my setup almost entirely automated early this year really helped me take advantage of every clear night I got. I have links below if you want to check out the uncropped original photos, as well as their specific acquisition and processing details
