NGC 4013 and NGC 4051 from my „Jade“ observatory
This is one of the first images with my new equipment on the second pier „Deep Sky Pier“ in my „Jade Observatory“.
NGC 4013 is an edge-on barred spiral galaxy and NGC 4051 is an intermediate spiral galaxy, both situated in the constellation Ursa Maior.
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 those with a redshift greater than 3.
The most distant of them is:
SDSS J115921.22+435303.9 with a redshift of 3.41 and an apparent magv of 21.14 (SDSS DR17).
