Nice work on a mini glob. Had  a look at framing this one last night, but it was too small in my more widefield rig.

it was too small

Small ?! With 93 light years across !? ... Thank you Matt ... my comment was a kidding ! My 305 mm GSO has a very good resolution, around 0.65 arcsecond per pixel. If I can register small DSOs .... in other way I can not register large DSOs. I haven't field of view to them.

As I use DSLR, and my GSO is newtonian reflector .... I can not use reducer. I don't get focus with it. Because this I do many stars cluster and  small DSOs.
