IC342 - The Hidden Galaxy

Revision title: Reprocessed in Pixinsight

Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

IC342 is indeed known as the "Hidden Galaxy" because it is hidden on the opposite side of the galactic core, with the result that this object is hidden or lost in thousands of stars. This makes this fabulous object very difficult to image.
This image was captured using a quartz 200/800 guided newtonian and an ASI294MC Pro cooled to -10°. Processing included the usual steps in SIRIL (stacking, colour calibration, gradient extraction). The outcome is the combination of a starless improved in Astrosurface and GIMP and an improved starlayer obtained in GIMP by computing the difference between the starless and the non-starless images.

188x300s of lights with the usual callibration files.
TS-200/800 UNC Quartz
ASI294mc Pro -10°C gain 121, optolong uv-ir cut filter
svbony 106 for guiding
ASI120MM for guiding
EQ6-R pro
SIRIL, Gimp, Starnet++, astrosurface for processing and post-processing

I hope you enjoy it. As always, any comments and advices aiming at improvements are much welcome.

Clear skies,

Patrice

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
