[Caldwell Index]

Mike Lancaster captured this image of Caldwell 42 on the 10th November 2023. The image comprises 104 x 20s exposures taken using an Altair Hypercam 26C at 300 gain (plus darks, flats and flat darks), through an Orion Optics UK AG12 Astrograph mounted on an EQ8 mount. A 0.95x Wynne Corrector and Astronomik CLS-CCD filter were also employed. No guiding was used on account of the short exposures. Images were acquired using SharpCap, and the processing was entirely performed in PixInsight. Zoom in - can you spot some faint galaxies here and there?   Image Credit: Mike Lancaster.
