M106

Switched to ISO200 for this session and it seems to work well. I am learning more about optimum exposure time and expect I don't need to be going 600s in a red zone. I want to quantify the light pollution but expect I'll drop it back just to get better star quality lower risk of per-sub issues. In this session I had to toss 1/4 of subs for clouds, oh well. I also changed up how I took flats and it was a mistake. I got vertical banding. Stacked the lights w/o flats and got a very similar pattern. But used flats from last week and it was magically fixed. Need to play around more...

Description: Trying out the EZ Processing Suite in PixInsight. Used EZ Decon and EZ Soft Stretch. I see a bit more color gradient in the background of this processing but the core of M106 is much crisper.

Description: Went back and looked at the frames I had rejected with Blink in SubframeSelector and kept 2 from that set and tossed 1 from the set I had integrated before (high eccentricity). And a bit more considered approach to deconvolution, though still almost push button with EZ Decon. Super small improvement, barely seen unless looking at faint stars which are a little bit more defined. I'll take it..

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.
