Elephant's Trunk Nebula, IC1396, Mosaic in Ha (legova)

Elephant's Trunk Nebula, IC1396, Mosaic in Ha

Completed 6 panel mosaic. An average of 4 hours of subs per panel.

Version F - added extra subs to even out background noise, so up to 5 hrs per panel. TVGDenoise version, think it looks a little better stretched. Not sure if it's as good 1-to-1... denoise maybe affected the faint nebulosity too much.

Version D/E - Finished the Ha frames, mostly. I'll maybe collect a few more subs for a couple of the panels to better match the grain with the other panels. I plan to continue with SII and OIII when the moon isn't around.

----

Captured 3 of 6 planned panels in Ha for of a mosaic of IC1396. Each panel contains 3 hours of data. Minimal processing applied - no flats or background extraction, just some stretching to normalize the panels, GradientMergeMosaic to combine the panels, a slight stretch and LocalHistogramEqualization to improve the contrast on the merged image, and a tiny bit of noise reduction with AtrousWaveletTransform.

This is going to take a while to complete.

Version B - Merged linear images, stretched afterward.

Version C - More progress. Partial data for lower left, needs more light. Will work on real NR when I finish the 5th and 6th panel. Very quick mix for this version, but I'm getting more comfortable with the mosaic process. Got the flats problem worked out, so I calibrated correctly this time.

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.
