There must be a way to do this, but I don’t know where to start.

Given a star (or other object, or a RA and dec), and a radius, what are the (say) 10 known deepest sky objects in this area, ordered from farthest to closest (with estimates of their distances)?

Currently interested in the area between Capella and “the kids” (eta, zeta, and epsilon aurigae). See attached.

    $\begingroup$ More than likely the true answer is some galaxy far too redshifted to see, without any name. So I assume you mean named, viable light objects? $\endgroup$

    $\begingroup$ Actually, I’m interested in the redshifted objects, even if unnamed. However, as a related question, “deep-sky” meaning “visible” light would also be a nice thing to know. $\endgroup$ Nov 13, 2022 at 5:48

    $\begingroup$ The Cosmic Microwave Background Radiation (CMBR) was emitted 380000 years after the big bang, which occurred about 13.8 billion years ago. The CMBR is a named object in the sense that it does have a name. It's everywhere and anywhere one looks. $\endgroup$ Nov 13, 2022 at 6:41

    $\begingroup$ @BruceSimonson You can query the Gaia tables at the Gaia archive. There is a drop down to select what you want to query which defaults to the DR3 source table since that's the one that is most useful for most people $\endgroup$ Nov 13, 2022 at 9:48
