Andromeda Galaxy Mosaic

I captured a two-frame mosaic of Andromeda with a 10" CDK and Apogee U16M from a dark sky site, then added color data from a HyperStar 9.25" and ZWO ASI294 camera from my backyard. 10.33 hours total exposure time over two nights.

I used an Optolong L-Pro for the basic color data, then added data from an L-eNhance filter which brought out the red HII regions.

Capture and stacking in MaxIm DL. PixInsight for background extraction, color balance, non-linear stretching, deconvolution, noise reduction. Microsoft ICE for mosaic composition. MaxIm DL again for alignment of the luminance mosaic with the color images. Photoshop for combination of the L and color data, plus further enhancements.

Monochrome:

AG Optical CDK 10" f/6.7, Apogee U16M, Baader L filter, 22 x 600 sec per frame, SQM 21.4

Color:

Celestron 9.25" SCT, HyperStar v4 f/2.2, ZWO ASI294MC, Optolong L-Pro = 120 x 60 sec, Optolong L-eNhance filter = 30 x 120 sec, SQM 20.1

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.
