NGC7497

Almost gave up on this data I collected this summer. Between tracking down the hot spot I had in my flats, vs two trips to the observatory, I had no hope of working this data out.

Picked up this stack, tested L first and it seemed okay. Had to manually calibrate as I had shot flats back in august for several mornings and nights and didn't know which one worked and which one didn't. Next came RGB, different story as the data was almost trash. R channel had to be dumped and G and B had gradients. Picked up new data for R channel alone to see if it worked and it did with one problem. With the baffle extension in place, the region surrounding the diffraction spikes had an extra color during channel combine that I did not see with the old R data. I'm like what the heck! Back to old R data for star colors and new R for signal.

Took them through, happy that I was able to get an image out of this stack.

Hope you like it. 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.
