Subject: Question about beta Andromeda and 404
|
In the Peterson Guide( latest version) on page 144, the sky chart
shows 404 next to Beta Andromeda. What object is 404?
Thanks.

NGC 404 is an otherwise ordinary galaxy; once beta is moved out of the
field of view, it is not terribly difficult to see from dark skies.
Nonetheless, my nickname for it is "Galaxy Not Found"--a nickname that
may be increasingly opaque. :)

Hi, Brian, and that was actually my initial response also -- maybe
from trying too many outdated Web addresses <grin >.
Most appreciatively,

Thanks all for the info.I have a 4.5 Dob. Will I be able to see it?
Clear Skies.

Ahhhh. Not my thing, really, visual astronomy. The visual magnitude
(Mv) is given as 10.2 while the limiting magnitude of your Dob should
be between 12 and 14, depending on how one calculates it. That assumes
dark skies, of course. The problem with NGC 404 is the closeness of
Mira, the glare of which may overwhelm the galaxy. Guess: It will be
visible, but it will look like a dim star star. Give it a try!
Also, please see <http://www.ngcic.org/dss/dss_ngc.asp >. Click through
to NGC 404 for more details.

I found it pretty easy with a 6" f/8 refractor, but you need magnification to
get separation from Mirach. At 50x: no. At 100x: yes.

Coincidentally, I photographed Mirach (Beta Andromedae) and NGC 404
about 10 days ago. The photo is not great, so I was not going to post
it. Here it is, for a limited time:
<http://www.davidillig.com/ast-mirach-ngc404.shtml >.
Googling NGC 404 turns up a lot of interesting stuff, including an
article entitled "...the galaxy without dark matter."

Not to pick a nit, Big D, but isn't 11.1 light years awfully close for a
galaxy? ;) - Chris

Not if it's very small and very dim :)
That *is* nitpicking a typographical error, but you are forgiven.
I am forgiven for making the error because I am an amateur astronomer,
not researcher. I have no means of measuring the distance to a galaxy,
and must take the word of others concerning distance. Others say that
the distance to NGC 404 is about 3.42Mpc from Earth.

Hi Bruce,
NGC 404 is a mag 11 galaxy less than 7 arcminutes from Mirach (beta
Andromeae)
Clear Dark Steady Skies,

NGC 404, also known as "Mirach's Ghost". It's a lenticular galaxy.
