M31, Andromeda Galaxy

Andromeda Nebula, or Galaxy, is a barred spiral galaxy with diameter of about 220,000 ly approximately 2.5 million light-years from Earth and the nearest large galaxy to the Milky Way. (Wikipedia) The satellite galaxies M32 and M110 are also visible in the final image. This data was collected on Feb. 9th, only 26 light subs of 180sec exposure each.

Equipment used: WO Z73 doublet apo refractor on iOptron GEM28 mount with GPS, 0.8x FR FF, ZWO 294MC Pro main camera and ZWO 120mm guidecam, ASI Air Pro and Optolong UHC filter. All powered by two Jackery units.

Totally new integrated stack using the latest WBPP script in Pixinsight with 40 darks and 60 flats, re processed in Pixinsight and final touches using Paintshop pro.

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.
