Re: (IAAC) Obj: NGC5134 - Inst: 56CM f:4.1 StarMaster Dob.


I know I'm a bit late for this post, but I have a question about your
observation of NGC 5134. I downloaded an image of this galaxy on the STScI
web site and I found something strange around the object, outside the halo
you describe. It is visible on every survey that STScI provide on the web
site. I didn't see it first, but after a couple of minutes, you can see a
second kind-of-halo surrounding the entire galaxy. Am I dreaming? If this
second halo really exist, it this possible to see it with a large reflector,
like the one you have, under a very dark sky?

Thanks for your help!
