Above is the Flaming Star Nebula (and some friends!) at two different focal lengths. The more wide shot was taken at 180mm and the more close up shot was taken at 380mm.
The 380mm was taken with the Meade Series 6000 80mm Triplet APO while the 180mm was taken with the TPO Ultrawide 180 f/4.5 Astrophotography Lens & Guide Scope. The plan for the TPO is to mainly use it as a guide scope, but since it is a triplet (like the Meade) I wanted to get some imaging done with it as well. The setup for this, at least for me, was, to say the least, uncomfortable, but I was able to make it work and get some data!
