Red stars in NGC 884

Speaking of carbon stars, I was poking around in the area of the Rosette
Nebula (could have been way off too) when I stumbled across a _very_ red
star. Any guesses, that I might be able to go back and look for it again?

Stephen -

I don't know this one, but that is a pretty vague set of coordinates
you gave. - The following is list of potentials I pulled off Simbad.
Maybe V668 Mon?

Rosette Neb 06 31 40 +04 57.8

M class with reddened B-V within 2 degrees of Rosette Nebula, by
ascending distances from Ros Neb

Thanks for the data. I was just poking around the sky with my 12.5" Meade
Starfinder Dob . . . snip I like red stars, especially carbon stars. . . .
I stumbled across a _very_ red star. Any guesses, that I might be
able to go back and look for it again?

Stephen -

If you have a deep magnitude reaching 12.5" DOB and are into carbon
stars, I suggest you download and install Alksnis's 2001 carbon star
catalogue into your planetarium software. Alksnis's catalogue looks
the most current and comprehensive carbon star catalogue. See:

http://cdsweb.u-strasbg.fr/viz-bin/q...tars+catalogue

You can get the catalogue via ftp at:

ftp://cdsarc.u-strasbg.fr/pub/cats/III/227

or interrogate it directly through Simbad at:

http://cdsweb.u-strasbg.fr/viz-bin/V...source=III/227

Looking at a 2 degree swath around the Rosette Nebula returned alot of
promising carbon star candidates, with catalogue cross referencing,
for your red star near the Rosette Nebula. Most were on the list that
I posted previously.

In case others are wondering, I did this in Cartes du Ciel using the Cartes
"catgen.exe" utility. First I had to convert the .dat files to something I
could read in Notepad. That means opening up the files using EDIT in a
command window, and then simply selecting File | Save. Now that the format
of the catalog.dat appears correct in Notepad, do the same for the readme,
which describes the catalog line (row) entries on a character by character
(column) basis. You need this for catgen.exe which allows you to group
columns, under an associated heading.

Run catgen.exe and select the appropriate "column" name from the check off
boxes in the upper portion of the interface box (the "string" selesctions
allow you to apply an alternate name for customization). Then in the lower
portion of the interface box, select the columns described by the catalog
readme. This takes a bit of reasoning to understand, but once you get it,
you can format and generate the carbon star catalog for inclusion under the
Cartes "catalog" tab, in the same place where you find the Stars1, Stars2,
Nebulae tabs.

It took me around a half hour, having never done it before. It was way cool
to turn off all of the other catalogs and have Cartes display only the
carbon stars. There are a whole lot of them defined along the galactic
plane.

Any chance you could zip your Ciel compiled catalogue and post it on
your web site? I would like to grab a copy. (If you do not have a web
site, I would appreciate receiving a copy via email at
. My email attachment size limit is 2Megs.)
You also might want to consider sending the catalogue to the Cartes du
Ciel site. I'm sure they would be interested in adding it to their
catalogue page. Clear skies - Kurt
