Heart and Soul Nebulae at 200 mm in Ha

This two panel mosaic image of the Heart and Soul nebulae (IC 1805 & IC 1848) was captured on the nights of December 22 & 29, 2020 using a medium telephoto lens, a dual narrowband filter, and a OSC DSLR. This is image includes the H-alpha data from the red channel. This cheap, used lens turned out to be a pretty rough character. I like this focal length, but I think I'm done with this lens...

Imaged with 200mm/F4 Nikon at F/4, STC Duo Narrowband Clip Filter, and full spectrum modified Nikon D5300.

Total integration time was ~2 hours using 29 subs at ISO400 x 240 sec (IC 1805) and 35 subs at ISO400 x 240 sec (IC 1848). Pre-processed and integrated using PixInsight Batch Pre-Processing (BPP) script. Images calibrated using darks, bias, and flats. Cropped using dynamic crop and removed gradients using ABEExtracted red/green/blue channels from HDR image using BatchChannelExtraction script.

R (Ha data) and Sum of G+B (OIII data, tossed due to being a real mess) channels individually post-processed in Pixinsight: Cropped, gradient removal with ABE. Noise reduction using EZ Processing Suite for PixInsight Denoise. Further processing using masked stretch, hdr multiscale transform, local histogram transformation and morphological transformation processes.

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.
