Mike Lancaster took the following image of Lower's Nebula in the northeast of Orion on the 3rd March 2024. The image comprises 33 x 4 minute 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. This setup was guided in PHD2 using an SXV Lodestar camera attached to a piggybacked ST-80. Images were acquired using SharpCap, and the processing was entirely performed in PixInsight.  Image Credit: Mike Lancaster.
