The Whirlpool Galaxy taken on April 19, 2020

This was the first image I was able to use with AutoGuiding; I had much trouble getting it to work with SBIG hardware but finally was successful. Still need to work on the settings as I am still limited to max 180 seconds on a perfect night.

All frames were stacked in DeepSkyStacker using a 3xDrizzle and a Median method. This photo is the first photo processed with the new workflow guide from Trevor Jones of AstroBackyard. While a much more time-consuming process, I believe the work has paid off compared to my previous attempts at this data.

Each channel was taken into Photoshop then multiple small curves and levels adjustments applied. For the gradient, I copied the layer and blurred it completely using a dust & scratches filter. I then "applied image" this blurred version on my previous layer and that greatly removed the gradient (this is in place of taking Flat and Bias frames).

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.
