This image of M48 was captured by Mike Lancaster on the 21st March 2022. It is comprised of 6 x 5 minute exposures taken through a 10" Meade ACF SCT using a 0.5x Mallincam Focal reducer, Optolong L-Pro 2 filter and Mallincam Universe camera at 20 dB gain and full resolution. This setup was guided using an SXV Lodestar camera through an OVL off-axis guider and PHD2. The images were stacked in Deep Sky Stacker, and cropped and processed in Nebulosity 4 and Photoshop Elements 2020.  Image Credit: Mike Lancaster.



Adrian Brown captured this image of M48 in February 2012. He comments: "It's another photograph with my Skywatcher 80EDPro refractor and ATK16HR camera but, as an experiment, I attached two crossed solder wires, painted matt black, across the front of the refractor's dewshield to produce some diffraction spikes on the brighter stars. I've always liked open cluster photographs with diffraction spikes and I quite liked the effect of the wire mask although tinkering like this and adding artifical elements will probably upset the purists in the hobby!" The photograph is comprised of 8 x 2 minutes Red, 6 x 2 minutes Green and 6 x 2 minutes Blue with Astronomik RGB and CLS light pollution filters.  Image Credit: Adrian Brown.
