Mike Lancaster captured this image of M92 on the 8th August 2023. The image comprises 60 x 10s 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 Optolong L-Pro 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.

This image of M92 was captured by Mike Lancaster on the 21st July 2021. It is comprised of a stack of four 4 minute exposures taken with a Mallincam Universe camera attached to a 10-inch Meade ACF SCT on an EQ-8 mount. A 0.5x Mallincam focal reducer was also used. The camera was set to a gain of 16dB, a gamma of -20, a contrast of 0, noise reduction on and 2x2 binning. No guiding, flats or dark frames were used. Stacking and processing was done in Nebulosity 3.   Image Credit: Mike Lancaster.
