M15 (October 2016)

Here is M15 through the CFF290 Classical Cassegrain at f/7.93.  I have shrunk the image somewhat because I was experimenting with focus and collimation, and some of the sub-frames of this object were not as sharp as the later frames.  This is just 12x240" through the SXVF-H9 and CLS filter.
