Here we have well known targets of M81 and M82. While processing numerous times I became interested in all the faint and fuzzy background galaxies. Watching videos by @Franklin Marek I learned a few new tricks.

https://www.youtube.com/watch?v=9VmVUadJbxY&t=1s Annotate images beyond the basic Pixinsight tool using the TypeCat script.

https://www.youtube.com/watch?v=a9j2sY3w--Q&t=504s Use free software Nova.Astrometry.net and Aladin to visualize your image while it is layered with different catalogues such as Simbad and Gaia.

While using Aladin I sorted all the Simbad objects in my image by redshift and was shocked to find a handful of quasars. The most distant one being SDSS J100048.55+694926.2 with a redshift of 3.58323. These photons traveled some 9.8 billion light years to reach my telescope.

Version A: Includes the full field captured plus a focus area feature in the top right highlighting of the quasar.
Version B: Annotated to show background galaxies.
Version C: Annotated to show the globs in M81.
Version D: Crop showcasing the wonderful M81 and M82.

Other notes: HA was added to the RGB combine using the ToolBox scripts on ContinuumSubtraction + CombineRGBandNarrowband.

Hope you enjoy. Let me know your thoughts and critiques.

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.
