Here is my first post after a long time of weather and technical related problems. It is a single 10 min exposure of M13 done to test the FOV, focus, collimation, mirror quality of a BRC-250. I detect a lot of defects in the image but it gives one the sense of light grasp this scope has.

BRC-250 f/5
STL-11000M
10 min (no flat)

Hi Tom,

Looks like your BRC is performing well with that big chip. Did you have someone collimate it, or did you work through that yourself? You'll proably need to take flats with almost any other type of object - but this is a nice "first light" for your set-up. How are you handling focus?
