M20 test image

Here is an image out of Swan Reach Imaging. I have been testing a new imaging rig which we have installed in the big shed. There is still a few small teething problems that need to be sorted but I am quite happy with the new camera (ASI6200) and new mount. The field of view of the camera is quite wide overall and imaging at 2x2 bin the imaging time appears to be cut down markedly. The native 1x1 bin produces sub frames that are 128mb in size and absolutely huge. My preference is to use 2x2 bin which still produces a large 29mb sub frame. The noise level is markedly reduced from what I have become accustomed with the older CCD tech.

Some things to bear in mind are that the tilt adjusters do leak light and need to be taped off to prevent light leakage or use a 3D printed baffle that screws into the Big OAG. And; I think ZWO should really consider making cameras with a shutter or a blank frame in the filter wheel to allow remote darks.

The image is of the Trifid nebula (M20). Imaging time is a paltry 3 hours in total integration.
