Mike Lancaster captured this image of Caldwell 47 on the 21st August 2023. The image comprises 65 x 20s exposures taken using an Altair Hypercam 26C at 100 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. Image Credit: Mike Lancaster.
