M92. PHD locked up again after I went to sleep... so I lost the B and L I was planning on. Still, demonstrates the capabilities of the scope and I was extremely pleased with the guiding from my DIY AT 8x50mm finder-guidescope mounted on a C5. The C5 is known to have a small baffle tube which makes it unacceptable for AP on large format chips; but it seems to be well-suited to the C5. I had actually round stars from edge to edge; something I've had difficulty achieving with my AT8IN.

New favorite scope!
