About this image

This is a first-light image with my new mono camera setup. I've paired an ASI 533 camera with a 1.25"/31mm filter wheel fitted with the Astrodon filters from my QSI 683 camera. I've also resurrected my Lodestar guide camera in an off-axis guider. So I have the colour performance of the QSI camera but with a modern sensor.

The image is a crop from the original at 100% resolution to preserve the captured detail.
