Scope: WO Zenith Star 81mm f/6.9 with WO 6AIII Flattener/Focal Reducer x0.8; Cooled Camera: ZWO ASI 2600 MC Pro at 100 Gain and 50 Offset; Mount: iOptron GEM28-EC; Guider: ZWO Off-Axis Guider; Guide Camera: ZWO ASI 174mm mini; Focuser: ZWO EAF; Light Pollution Filter: Chroma LoGlow Broadband - 2"; Software: Pixinsight (for processing) and Photoshop (for inserting the inset).


Regarding the inset: The inset shows the image prior to post processing exhibiting a faint artifact at the 2 o'clock position on the core which may be indicative of the source of a plasma jet in M87. This feature is swamped out during post processing. I photographed M87 (an Elliptical Galaxy in Virgo) on 7-9 March 2023 from a Bortle class 8 area. Having acquired 51x300s subs, which equates to 4.3 hours of total exposure, I processed the data in Pixinsight.
