Soul Nebula (IC1848) in Ha

Imaged the Soul Nebula (IC 1848) on the nights of January 19-20, 2021. Image was captured using an APO refractor and full spectrum modified DSLR through a dual narrowband (Ha/OIII) filter. This image is the H-alpha data (red channel) data.

Imaged with WO GT81 at F4.7 (382 mm focal length) using Flat6A II field flattener/0.8x reducer, Optolong L-Enhance dual narrowband filter, and full spectrum modified Nikon D5300. Total integration time of ~7 hours using 68 subs at ISO400x360 sec.

Pre-processed using PixInsight Batch Pre-Processing (BPP) script. Images calibrated using darks, flats, and flat darks. Extracted red/green/blue channels using BatchChannelExtraction script. R and G+B channels registered and stacked using StarAlighment and Integration. R and G+B channels individually post-processed in Pixinsight. Initial processing: Cropped, gradient removal with ABE noise reduction using the EZ Processing Suite for PixInsight EZ Denoise script. Additional post-processing in Pixinsight: masked stretch, curves, local histogram transformation, morphological transformation, and a final round of noise reduction using the TGV denoise process.

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.
