SH2-190 and SH2-199 - Heart and Soul Nebulae (Ivan Raichev)

SH2-190 and SH2-199 - Heart and Soul Nebulae

There is a lot to be seen in the Heart and Soul nebulae. I imaged this area of the sky last year and hoped to capture the whole region in a 2x1 mosaic. However the active region is bigger and my efforts were with limited success. This year I saw several consecutive clear nights in the forecast for October and decided to revisit the Heart and Soul nebulae but this time with a proper 2x2 mosaic.

So in total I dedicated 4 nights to this project and hoped to be able to add the data from the additional two nights from October last year. Imaging was smooth as there were some clouds only in my last imaging night.
Stitching the data turned out to be difficult. Merging the four panels from Y2022 was the easy part. I did it with the PhotometricMosaic script in PI which performs flawlessly for this task. The difficult part for me was adding the two panels from Y2021 as they span across the center of the mosaic and the PhotometricMosaic script can not handle such tasks. So I turned to the Gradient Merge Mosaic process in PI. Here the additional panels need a lot of trimming of border stars which if not managed properly can create a lot of nasty gradients. At the end after a lot of trial and error I managed to make a seamless mosaic from all of my data from Y2021 and Y2022.

Unfortunately my wife got injured in the end of October and currently most of my time is dedicated to helping her and my kid and taking care of the home responsibilities. That's why it took me a while to process the data from October but today I finally managed to do it and upload it.

I love this region of the sky. It is full of interesting clouds, shapes and colors.

CS,
Ivan

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.
