Deer Lick Group - NGC7331

Acquisition type: Lucky imaging

During the last Summer, in August in particular, I spent some amazing nights under a very dark sky (SQM 21.7) at 2000 m altitude, in the Dolomites. I decided to capture the luminance of this very nice group of galaxies but the result after the processing was quite disappointing. It was one of the first pictures of deep sky I produced and I though that bad results were due to the chrominance that was obtained from my light polluted sky. I recently looked at that picture and I recognized I made some mistakes in almost every aspect of the postprocessing so I decided to reprocess it considering in the mean time I learned some more concepts, so I think this result is much better than the previous one. I also have to say that in this case, deconvolution with parametric PSF worked much better that the external PSF in enhancing the details around the nucleus of the galaxy.
I hope you like it.

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.
