Ursa Minor Dwarf from my „Jade“ observatory

This is another image with my new equipment on the second pier „Deep Sky Pier“ in my „Jade Observatory“.

Ursa Minor Dwarf (PGC 54074) is a dwarf spheriodial galaxy in the constellation Ursa Minor.

Data calibration, registration and the final processing was done with PixInsight. The result was as follows:

There are so many quasars in this image that I can only show the ones with z>2. The most distant of them is:

WISEA J151452.78+670431.3 with a redshift of 3.2.
