M45-4 Panel Mosaic

M45 is my favorite target so it is only fitting that this should be my first attempt at a mosaic. Overall very impressed with PI and how it handled merging the panels.

This was an interesting night of learning gear and software.

The first time I have used SGP Mosaic tool. The first time using manual rotator in SGP to set my camera angle. Learned that your camera orientation has to be accurate or as after I wasted 1hr of imaging when the second panel started and I found that my camera width and height were reversed in the mosaic tool thus rendering useless images . Oh, and let's throw in a meridian flip in panel 4 for good measure! SGP is powerful software. I have been using it for 5 years and it just amazes me with what it can do automatically.

Then I had to learn how to create the mosaic in PI. Using Warren Keller's "Inside PixInsight" made this a breeze. Thank You Warren!

I used David Ault's dnaLinearFit script to match the the panels field illumination. This script is worth downloading as it worked with awesome results. Thank You David!!!

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.
