Heart and Fish head Nebulae

The data for this image was collected during 14 days in period from 17th of October till 9th of November 2021 (with few pauses because of weather conditions and full Moon). At the end I got 12 panels of SHO data.

It was my first and worst experience with mosaics. At the end of the data acquisition I was afraid to process it because of lack of knowledge of PixInsight. Overall it took me 6 days to process it for the first time. For sure for the second attempt it won't take more then a day, but it was golden experience.
It's heavily processed picture because I used workflow which includes star removal. The final image has 11042px x 12750px resolution with fine details (but my current subscrition allowed me to upload just half of it).

Hope you will like this image. 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.
