Sh2 135 HA RGB (Warp Speed Processing)

Had an aircraft run through one of my 1800s subs and I said, maybe for a change let me try to process with the absolute minimum of files. This is pretty bright and I am trying to get close to a full set of Sh2 images done.

So I stacked with the minimum for PixInsight of 3 images and denosied with Topaz Denoise on a starless image. I then put the stars back in as normal and frankly it is hard to tell the difference from 8 HA images or for that matter 12. To me at least.... hours less work...

From galaxymap:

Ionised by an O9.5V class star and located at a distance of 1900 parsecs.[1]

This is probably a blister on a dark dust cloud in front of the bright nebula.[2]

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.
