New processing of IC342

By astro-friend Marc Verhoeven.

IC342 re-processing the original data by M. Verhoeven

Compared to the original image it’s clear that a lot of stars became a lot dimmer, bringing out the main subject. Not-so-hidden galaxy anymore 🙂 !!

IC342 the ‘hidden galaxy’

IC342 is a spiral galaxy of magnitude 9 in the northern and obscure constellation of Camelopardalis (‘the Camel’). The low surface brightness makes this a challenging target for clean images. The size is about 20×21 arc minutes, or comparable to almost half the Moon.

IC342 Drogenberg Observatory, Sharpstar 76mm F4.5 APO, 344x120s with ASI2600MC

On the image a nice open star cluster (top left) Berkeley 10 (credit O. VanAelst) and some small galaxies are visible like eg. UGC 2789 magnitude 17

The image was obtained on 4 different nights in September and October 2024. Some nights high Cirrus-clouds were present, which can be seen around the brighter stars as a veil.

Equipment: Sharpstar 76 EDPH F 4.5 camera ASI2600MC and mount GM1000, no guiding.
