Two-Panel SHO Mosaic of Sh2-126 and LBN 437

2-panel mosaic taken over a couple nights of Sh2-126 and LBN 437

Acquired 2 separate SHO sets, 1 set for each panel, 26 x 300s images @ -10c & 100g, 1x1 bin, ~95% were usable.

Blink / Subframe Select, Calibrated (100 Dark, 60 Flat, 100 Bias), Star Aligned all images with PixInsight. Used the Normalized Scale Gradient for integration - this knocked several sub-frames out.

DBE each frame for Sii and Oiii only, Star Aligned with Mosaic Union to generate a template for Star Alignment, panels were 'matched' images to the template with Star Alignment. Registered/'matched' panels were dnaLinearfit prior to GMM.

For Ha, Sii, & Oiii channels: Dynamic Cropped, SCNR, TGV, MMT (& duplicated the Ha here for the Lum), EZ Soft Stretch, StarNet for star removal, and Channel Combine Ha to R, Sii to G. and Oiii to B.

The duplicated Ha -> Lum was Dynamic Cropped, EZ Noise'd, Mask Stretched, STF Stretched, HDR, DSE, LHT, MMT, EZStar Reduction, and LRGB Combined with the PixelMath SHO image.

The image was Curves modified w/ masks, Resampled, and Annotated.

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.
