The Horsehead and Flame Nebula is a classic winter target and one of the most beautiful targets in astrophotography. I took this on my Redcat 51 with an ASI533MM mono camera which I believe framed this target perfectly.
The Flaming Star & Tadpoles Nebula
Another favorite winter target, I was able to frame both these nebulas using a Redcat 51 and ASI533MM.
