The Whale and Hockey Stick Galaxies Widefield with Distance Annotations

I processed this image with the goal of revealing other galaxies besides the two main targets in an effort to determine their distances from Earth.

I used Pixinsight's Annotation script to label the galaxies cataloged in the PGC catalog. I then looked up each galaxy in the NASA/IPAC Extragalactic Database and logged each one's Hubble Distance in Mpc's. A simple formula to convert Mpc's to light years was used to notate their distance. One particular galaxy, PGC42593 is apparently 735 million light years away! I don't think this is the farthest object I've ever (accidentally) imaged, but it is the farthest I've notated so far.

PGC 1960000 - PGC 1989999 appear to not be present in the NED, and I did not attempt to calculate their distances.

I'm still learning a lot about the Hubble Constant and red shift in relation to distance.

Clear minds and clear skies!

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.
