The neighborhood of Perseus A
This is the area around the galaxy "Perseus-A" in the constellation of Perseus. This galaxy as part of the Perseus galaxy cluster is about 240.000.000 light years away from our milky way. It is a well known radio source. The Perseus galaxy cluster consists of about 500 galaxies.
Unfortunately, the test photo above is not as sharp as it should be, since the telescope was slightly out of focus during the image aquisition. The integration time was 2 x 10 minutes using a 4 inches f/3.6 telescope (second light), this was not long enough to capture its numerous details.
