Whilst the weather remains appalling, I thought I would re-process my data from the other month, to see if I can draw forth that notoriously difficult OIII-blue, that I always struggle with. I am pleased to say that I have, based on an idea from a discussion with a fellow astrophotographer on this forum. Basically, I super-stretched the OIII data to a level I would never do! and altered the blue channel, in order to adjust things accordingly. I hope others feel this is an improvement. What would I do without convolution of the noisy data and using the Ha as a Luminance!?

As I wrote last time, the Ha data I was very pleased with, but the OIII was tough to capture and the sky was pretty poor to be fair, as well. I got 100 Has at 4 minutes long each, and 72 OIIIs at 4 minutes long too. All in all the imaging time was 11 hours 28 minutes. Take care all of you, thanks. Simon

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.
