Slight cock-up last night ....

This morning I noticed that I had the direction for the temperature compensation the wrong way around for this particular profile in SGPro - no wonder I was having focus problems!

This might not be as good as it should be but it does show the main event after stacking.

I'll probably replace this with new data next time out once my new 4-element reducer arrives

Ha 600s x 9 -15degC

OIII 600s x6 -15degC

SII 600s x9 -15degC

Description: Overnight with the new TS-Optics field flattener, so far so good for the corners! Went for a more striking image this time, stacked with a new APP version, processed with Startools and finished with PSpro. 2hrs of Ha and 1.5 each of OIII and SII in 900s frames

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.
