So my first test image using the new gear I got The Zwo ASI071 MC PRO Cooled using the WO 73mm scope with just a flattener and no light pollution filter. Also the WO 50mm guidscope with the ZWO ASI290 mini guide camera. I just quickly took a 2hr session of this image along with another one which I will post shortly. Didn't come out too bad but I think I have dead pixels in my camera as you can see the dark circle at the lower right corner of the image. I'll contact the vendor about that and see if I can get a replacement camera.
