Heart and Fish Head nebula Mosaic

This was a first and pretty challenging Mosaic of the Heart and Fish Head nebula taken through a Skywatcher Esprit 120MM APO refractor. It was definitely a challenge capturing data in mediocre winter skys here in Mechanicsville MD. (Bortle 4-5 with average seeing) The total integration is approximately 33 hours or 8.25 hours for each of 4 panels in Ha, OIII and SII Narrowband using ZWO 7nm filters. Resolution is 8026x6254. Imaging camera was a ZWO ASI 1600 Mono cooled to -20F and guiding was performed using ZWO ASI290 mono camera and ZWO Off Axis Guider. Processing began with each narrowband channel stacked in Deep Sky Stacker, followed by buildup of an RGB panel in the Hubble Palette using Photoshop. After the panels were created and averaged, they were assembled into the Mosaic using MS Image Composite Editor. Final editing of the Mosaic was done using Photoshop and Lightroom.

Equipment:
Skywatcher Esprit 120MM APO
Skywatcher EQ6R Pro mount
Guider: ZWO ASI 290 Mini on Off Axis Guider
ZWO 7 position Filter Wheel, Ha, OIII, SII

Integration:
180 x 600 Second - Lights
20 x 600 Darks
45 x Flats (Ha, OIII, SII)

Software:
Acquisition: Nighttime Imaging in Astronomy (NINA)
Guiding: PHD2

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.
