I decided to give my ASI294MM Pro a night off and switch to the ASI 2600MC Pro using the Optolong L-eXtreme duo (HA and OIII) 7nm bandwidth pass filter for the first time. Under Bortle 6 skies during 90%+ moon illumination and below average/average seeing, I thought the filter performed admirably well, especially on the C11"EdgeHD at prime optics, f/10.

I prefer my 294mm but this camera and filter will be a great combo for live viewing/stacking and outreach (when we can once do them again).
