M31 mosaic - revisiting old data

[ONIKKINEN]

2x2 panel mosaic with an additional center panel for stitching the panels together. 60x30s per panel, except for the center which was 10x30s so in total 2h5min of integration. Shot with a RisingCam IMX571 OSC camera in a VX8 riding on an EQM35.

Captured last august and the image had some star shape issues due to guiding, focuser slop and a poor quality baader M48 extension that did not thread properly so i had to reduce the size quite a bit. Stacked at 0.5 scale in APP and then further binned 2x2 as an attempt to hide the issues. Further processed in Siril and Photoshop utilizing Starnet++V2 for some minor separate star layer, background and galaxy layer tweaks.
