NGC 1365 - now with extra BlurXterminator (Paul Muller)

NGC 1365 - now with extra BlurXterminator

What can be said about NGC 1365 that hasn't already been said by WikiPedia https://en.wikipedia.org/wiki/NGC_1365

Located in the "furnace" 9Fornax), it's about as far from an Arp galaxy as they get, classic barred galaxy with arms athat almost wrap back around on themselves.

What make this image special (to me) is that I processed it using the recently released BlurXterminator (along with NoiseXterminator) in addition to my usual lazy "load the subs into APP, press Integrate - get a coffee - throw out the crap subs . Repeat. Colour correct, sharpen, crop and export." routine.

This time I thought I'd give the newly released BlurXterminator a go, post-stacking, instead of my usual routine.

Here's the result - be interested to see what you think. Attached the "APP" version for reference.

Title: NGC 1365 - NoiseXterminator only

Description: This is the raw data from teh original image, no sharpening or post-processing beyond simple stacking and automated noise removal per the final image

Title: NGC 1365 - sharpened in AsotrPixelProcessor

Description: This is the de-noised version (previous revision) and then lightly processed using nothing but APP's built-in sharpening tool (set to 2.9 with Protect set to 3.9)

At a brief glance, to my inexpert eye, they're similar enough that my family wouldn't noticed the difference, but obviously you can clearly see the stars are now pin-points compared to the more natural looking PSF of the BlurXterminator version and generally the BXT version is a cleaner look, with the exception of a few of the faint background galaxies that are sharpened to to the point of looking synthetic.

Generally speaking, whilst it's a change in my workflow that I wasn't really anticipating (I LOVE APP's simplicity and immediacy of results), I think this is how I'll process all my data in teh future.

Thoughts?

Title: NGC 1365 LHaRGB - processed e2e in APP (no noise reduction)

Description: Here is the image I was about to upload before I saw the release of BlurXT - note teh colours are very different despite using the same colour calibration process, I suspect this has something to do with teh added boost to teh Red channel courtesy of the Ha data.

Also note the incredible boost that NoiseXterminator brings to the signal in the other versions, so much so that I had to use a far less aggressive stretch as a result of the improved SNR (it also highlighted a hidden gradient that didn't show up in APP version due to the lower SNR)

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.
