NGC1275

Friday night I had a nice observing session. The seeing was less than perfect, so I spent most of the time with deep-sky objects. One of the targets of the night was to observe some galaxies in Perseus. The only good one in the constellation is NGC1023. This galaxy reminds me a bit of NGC7331 in Pegasus in size and brightness - and some foreground stars decorate the view.
A bit further north is NGC1003. A faint fuzzy even in the 12.5-inch - I was a bit disappointed.
For a long time I have tried to locate the great and distant galaxy NGC1275. This is not a show object, but belongs to the "nice to have seen" category. On Tuesday night I finally succeeded. I realise that I have been searching a bit too far to the north, and since this is close to the milky way, the star field is rich, and makes it difficult to spot the galaxy. At 63x magnification NGC1275 only was visible. At 115x, however, at least three more galaxies could be seen. The negative photo in the NSOG is a bit difficult to use for identification, therefore I would be grateful if anyone could give me a reference to a better photo of this galaxy cluster.
It would have been very interesting to have a person like Dmitri around. He would probably have seen quite a few galaxies in the field.

Ah, Inge, I would love to have been around! All I can see here is clouds (but I'm heading South tomorrow). I have seen 1275 in ST80, it was not spectacular, except that it's quarter of a billion light years away.

Inge: NGC 1275 is apparently No. 24 of the "Caldwell Objects," and there is an excellent photo of it among the other galaxies in its cluster (all appropriately identified) on page 100 of O'Meara's book "The Caldwell Objects." I hope you have access to a copy of that book.

Inge--

albert highe has a big page on this topic, it's one of his chief observing projects--here's a link to a finder chart from him:

and here's a link to the page on the perseus cluster:

You can enlarge the jpeg and it's pretty nice.

p.s. check out the observing list for the cluster on the main page.
