Description

Vega is to the left, Skeliak to the bottom mid-left, and many deep sky gems throughout the rest of the image. This is a 1-minute livestack from SharpCap using a ZWO ASI294MC-pro camera at 10 degrees C, 50mm Canon FD lens with custom adapter at f4, and polar-aligned Ioptron skytracker on tripod. The actual 4144x2116 image includes about twice the field of this uploaded image, but then the stars are so tiny they aren't appreciated as much unless viewed at significant image magnification. The dyanamic range of this camera is remarkable, showing Vega at reasonable brightness while able to see so many deep sky jewels, at the same histogram settings during live capture, exposure/gain/black point/mid-point. The16-bit raw format used in Sharpcap provides over 65,000 brightness levels in the same image at the same settings.
