Flaming Star and Tadpole Nebula in SHO

All processing done in Pixinsight. I used HDR Multiscale Transform on the Ha data which really made the objects come into focus. The SII and OIII data were fairly weak so I had to do some pretty aggressive noise reduction on them, through a combination of MLT and TGV Denoise.

B

Description: More aggressive processing of the OIII channel, and a different SHO blend in PixelMath. I could really benefit from more SII data here, but that won't be happening any time soon.

C

Description: Even more aggressive denoise in the S and O channels using MLT. Lesson of the day is blurring the S and O to death improves the final image, at least when you're a bit starved for data like I am here. I also left more "green" tint on this go because I like how the SII shines in the Flaming Star when you don't do a full SCNR.

D

Description: Clipped the OIII to get rid of the gradient in the left corner completely. This shrunk the OIII in the Flaming Star, but you can barely see it anyway so I figured it wasn't much of a loss. Also did a bit more aggressive SCNR because I wasn't liking the green tinge of the last revision.

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.
