Date image was taken: January 05, 2025

Location: Ager, Lleida Spain

Data Acquisition Method: Personal Telescope Setup

Image Description and Details: For some this area is known, and for others not.
We located this HB3 supernova remnant in the Cassiopeia constellation, right where Ic1705 the fish nebula and Ic1805 the heart nebula are.
This supernova is one of the largest in our galaxy with 1.5ºx2º, it originated about 40,000 years ago.
In the image we can very faintly see 2 planetary nebulae. PN G132.8+02.0 and
PK131+02.1 or more commonly known as Abell 3.

It is an area with a very weak signal, although with the 23 hours of exposure I think I have obtained enough signal.
