M31 Andromeda

This is our nearest similar galaxy Andromeda, was able to capture over 4 consecutive nights, July 26th-29th in RGB. I used Ha to blend in the Hydrogen regions that make for the bright purple nebula regions. Still amazes me how fast the light can be captured with a RASA at F/2. Taken with a small ASI 1600mm and Baader Ha F/2 ultra highspeed 3.5nm filter. Baader F/2 RGB filters handled the broader color spectrum as well as the ASG Photon Cage for precise tilt and alignment of the optics.

Date:  July 26-29, 2022
Ha: 88 x 180 seconds
Red: 281 x 30 seconds
Green: 577 x 15 seconds
Blue: 284 x 30 seconds

Calibration Bias: 20
Calibration Dark: 20
Calibration Flats: 30 for each filter

Gain:  139 on Ha and 75 for RGB
Processing Software: Stacked in Astro Pixel Processor, captured using NINA, Processed in PixInsight

Telescope: Celestron RASA 11 (620mm focal @ f/2.2)
Filters:  Baader Ultra-Highspeed F/2 3.5nm & 4nm Filters.
Main Camera: ZWO ASI 1600mm-pro Monochrome
Tilt & BackFocus Adjuster:ASG Photon Cage
Mount: Skywatcher EQ6r-Pro
Guide Scope: William Optics 50mm Uniguide
Guide Camera: ZWO ASI 290mm-mini

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.
