About this image

My large ML6303 CCD camera is broken at the moment so I've put a CMOS ZWO ASI293 MC Pro on the back of my HD11. This is my first test image taken in rather poor conditions. Focussing is much easier with the CMOS camera since I can get video frame rates over USB3. The deadtime between images is much faster too.
