M13_QHY128C11F7_19x120 1x1

First light with the QHY128C.

I haven't imaged with the 11" EdgeHD at F/7 in quite some time. The F/7 reducer is very heavy and bulky. Having the full frame sensor of the QHY128C made things more difficult...still have some spacing issues. I haven't used autoguiding in almost 2 years and PhD2 wasn't cooperating with the Orion HDX-110. Switched out to Metaguide and it worked well, but the damage had been done. As a result this image is cropped from its native size(6036x4028) to 4235x2989.
