~ 190 (0.2 e-/ ADU) . Sampling at 0.135 arcsec/ pixel

Image size 3864 (8.7 arc min) x 2192 ( 2.9 arc min) for 2 min 20s at 11.5 fps = 1626 frames.

Stacked (autoselected 22% = 357 frames) and deconvolved using Biggsky. Exposure level, gamma and colour saturation adjusted in Affinity and finally image and HF noise decreased using RC Noise Exterminator at 0.3 using AI version3 at default settings.

(to get good focus used the Beehive cluster and Adjusted focus to get stars looking as small as possible and down to 16-18 pixel FWHM as estimated by Sharpcap focus tool)
