IC2177 - First Light with ASI294mm-pro

First image with new (to me) ASI294MM . No filter wheel, just threaded H-alpha filter directly into camera nosepiece.

This has been difficult to pre-process and I still haven't been able to calibrate out the amp-glow evident in right side of image. There is a discrepancy between gain settings used in MaximDL lights and calibration files that I hope will become less of a problem the less I use MaximDL.

Calibration files were collected in NINA.

Description: Okay, the issue with the amp glow stems from MaximDL reporting a different gain than 120 when "unity gain" is selected; I have *no idea* what Maxim did, but when I set the gain to 200 in NINA, I was able to produce darks that calibrated out the amp glow.

Am going to move to using NINA for everything with this camera.

Description: Less aggressive stretch. Going to just leave it alone now - still pretty impressed what this camera can pick up with just 1.4 hours of integration :)

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.
