Mosaic (2 x 3) taken during 4 short nights in my light polluted backyard with lights from nearby cities such as Strasbourg. Although the total exposure time is ~13 hours, the real exposure time has been ~2.5 hours per pixel in SHO narrowband.

Imaging was pretty straight forward using the new mosaic plan in ASIAIR beta. After setting up in the SkyCatalog on the tablet there was not much more to do each night than to just manually change the filters, set the start time for the plan and hit run - cooling, focus, meridian, guiding, dithering... I know from evaluating other great software such as NINA is even more powerful than that, but in the end I again came back using ASIAIR as EAA which is so incredible comfortable to run on the tablet.

So not shooting mono narrowband for a very long time I was alway a bit reluctant to overdue colors - and espacially dong starless versions. But with this large FOV of 4° in square format I could not resist... I think although pinpoint stars are really a good indicators for quality and the object scale I personally really prefer this version.

After waiting for several hours to do the normalization, registration and mosaic stitching in APP I was finally able to tackle RGB combination and L processing in PixInsight. Whereas RGB combination has been done straightforward with very little image processing other than initial stretch, Luminance as a stack of all three SHO narrowband images has been denoised and deconvoluted before applying to the RGB channels. The basic curves and histogram transformation has been started in PixInisight - but the final processing was done in Photoshop and stars removed with the new AI algorithm from StarXTerminator (amazing there were no artifacts left at all).

Hope you enjoy this version,
Clear skies!

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.
