M57, the Ring Nebula. I imaged this over the last few clear nights, a total of 4 hours 30 minutes. Imaged using a SXH694 camera on my Altair 6 inch Ritchey Chretien on the CEM60ec mount. 27x 5 minute luminance and 9x 5 minute of R, G and B exposures.Stacked using Pixinsight's WBPP script then all processing done in PI except for some final colour adjustment using Affinity Photo, mostly to enhance the faint ring around the outside of M57.
