IC342 re-processed by Jean Lammertyn

Jean re-processed the set of subs and retained 341 or 75% of the 2-minute subs.

The result is very impressive and offers a view on all nebulosity that surrounds the galaxy but also hides it from being very bright. This galaxy is very large and would fit within a half Moon. So the surface brightness is rather low, which makes it easy for the IFn and Milky Way nebulosity to dim it even further.

The image displays a wealth of information, not only IFN patches everywhere, but also galaxies and H-Alpha nebulosity to the right of the galaxy.

IC342 Processing: Jean Data: Joost 341x120s with EDPH76mm F 4.5 Sharpstar ASI2600MC UV/IR
Version with higher contrast

The bright nebulosity was not the intention of the processing. Apparently the brightness of the image shifted when the original TIF was saved as a JPG under Windows Photo software.

When starting from a PNG, the saved JPG did not brighten. This was the original intended result:

Comet Tsuchinshan-Atlas C/2023 A

A first visual detection of the comet after it’s perihelion on October 16th. It was visible by the naked eye.
