NGC4631 & NGC4656 - The Whale and Crowbar Galaxies

Another clear night last night. Was able to capture both the Whale Galaxy (NGC4631) and the Crowbar Galaxy (NGC4656 & NGC4657). The FOV of the Vixen worked perfect for this. I shot 107 x 300" subs and kept 85. I'm liking my new workflow where I use APP as an initial screening for good/bad subs. I can see the difference in that rejecting the noisier subs that I visually cannot detect is cleaning up my final images much better. There is far less work DBE and the rest of the final PI plugins need to do so my initial light plate is clearly much cleaner and much sharper. I'm sure all of the astrophotography pro's on this sight know that but it's nice to discover things like this yourself.

This is a very interesting pair of galaxies for certain and I like how they framed up together.

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.
