MilkyWay, 3 panel mosaic, Sigma 40mm Art

I learned several milky way image with Sigma 40mm Art, so tried 3 panel mosaic.

images taken at Death Valley Father Crowley Vista Point, actual SQM 21.76

ISO400 f/2.8 120sec 45 subs each, x3

here is APP 1.083 Mosaic setting

load 3 images

(if there was "duplicated stars" result, too much overlap. crop appropriate before loading)

Analyze 3000 Stars - depends on focal length. wider = more stars

set reference to center image

Register quadrilaterals scale Start 1, stop 10

　use dynamic distortion correction checked

　same camera and optics : remove check

　distortion margin 0.02

　registration mode = mosaic

　registration model = calibrated projective

　projection method = mercatorProjection

　move COP vertical = 19 degrees ( to adjust image center DEC = -19 degree)

　interpolation method = Cubic B-Spline

　no under/overshoot : remove check

Normalize

　mode = advanced

Integrate

　integrate = average

　weights = equal

　LNC degree = 4th

　LNC iterations = 5

　enable MBB checked, 15％

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.
