OBAFGKM
I like watching stars so here’s a little journey to the brightest stars using the OBAFGKM spectrum.
From Alnitak (the hottest and bluest) to Betelgeuse (the coolest and orangest).

First galaxy of 2025. I’ve always struggled with this one. The challenges are to bring out the detail of the core, getting some structure in the outer arms and battling the bright stars outside of the frame. But I really like the final result.
I also think I have some collimation issues but I hope to solve these in the next few clear nights under the full moon.
