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.
