MW2 - Angel Nebula

The central Angel Nebula - MW2 (Mandel-Wilson 2) - this was a tough one to process. Definitely did not have the total exposure time required to bring proper definition to the IFN.

As well - I installed PI 1.8.9 and used this image as a test bed for a few of the new tools / features - probably not the best choice of image for good experimentation / feedback.

I have been a fan of NSG, however it is no longer part of the distribution and has been superseded by a new and improved Local Normalization. I used the process defaults and I noticed no strange artifacts. I think it uses photometry as does NSG.

A useful addition for me was the Automatic Pedestal during calibration - I was getting zero value pixels and had been adding a small pedestal.

Used StarNet2. Tested it against StarX and saw very little difference - a slight bit better but this may be image dependent. I see a new StarX AI update is available.

Tested the Weight Optimizer script. Found it to be v e r y slow on just a 40 sub sample (settings issue perhaps) so used SFS to Keyword weight the subs and the selection of per filter reference images - so image integration used SFS for weighting and LN for normalization.

The most interesting change was the addition of the Generalized Hyperbolic Stretch (GHS) script. Used this for stretching with what seemed good results given my weak data. Watched a number of videos and played with the script’s sliders. I will definitely need more time with the tool - like the concept though.

I am looking forward to user experience, and explanations / demonstrations from the experts for these new features - I see GHS is already scheduled for TAIC in May.

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.
