Heart Nebula (IC 1805)

This is a 9 panel mosiac shot over the course of many nights. I faced a lot of challenges with the acquisition -- the first being the weather with clouds moving in the 2nd half of many nights. Another night, my secondary mirror dew heater didn't kick in strong enough / soon enough leading to a bunch of ruined captures. The other challenge was the light pollution to the north of me (Austin) so I had to carefully pick and choose captures where I could still effectively remove the background / have close enough matching backgrounds between panels. I then used the DNA LinearFit script to match the levels between the individual star aligned panels best I could, although after the final mosaic composite and masked stretch, there were still inconsistencies between the backgrounds that needed further refining. I processed it all slowly over the course of 2 months. PixInsight's distortion correction on the Star Alignment process didn't seem to correct 100% around the field edges either which was a bit of a downer. Definitely my most complicated capture as of yet, but I am pretty pleased with 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.
