Mike Lancaster captured this image of M103 on the 6th August 2024. The image comprises 64 x 15 second 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. Due to the short exposures no guiding was employed. Images were acquired using SharpCap, and the processing was entirely performed in PixInsight.  Image Credit: Mike Lancaster.
