Description

The picture has been captured (58 frames/s) with a Celestron SCT C8 with an effective focal length of 2600 mm.
Date and time: 10-09-2023 at 04:38 UT.

The used camera was a ZWO ASI178MC. A TS Barlow Cell (1.5x) has been attached close (~4 mm) to the camera sensor. The enlargement factor then turned out to be 1.3X, nearly optimum for the C8, considering the small pixels (2.4 um) of the camera.
Seeing was about 4-5.

Autostakkert AS!3 has been used for stacking 500 out of 1000 frames.
The further fine tuning has been completely done within AstroSurface V1 (wavelets, leveling, denoising, color balancing).
The final optimized result has been slightly sharpened with Topaz Sharpen AI.
