I’m selling my QHY 163M and 183M CMOS cameras and upgrading to the QHY 90A. This is a classified for the 163M. It is lightly used and in great working condition. There are purely cosmetic scratches and indentations (see photos) where the camera has been attached to the filter wheel. Included are the camera, usb cable for attachment to your computer, power cable for a 12v source to power the cooling system, 6-pin RJ11 cable for the guide port, 4 pin cable for attachment to a filter wheel, desiccant tube, and 1.25” nosepiece.

I've added an SHO photo of the North America Nebula that I took with this camera.

I will pay shipping USPS priority to lower 48 states. Payment through PayPal.
