RE: (IAAC) Observations wanted: NGC 6991

Steve -
I just received an e-mail from Brian Skiff and it appears the listed
position for 6991 is incorrect.  Here's what he has to say:
This is one of those objects where there are problems in modern sources.
The cluster is misplotted or given the wrong position.  An improved center
is 20 54.9  +47 25 (2000); the cluster is about 35' across, so it's a large
rather sparse group.  It lies on the _west_ side of the mag. 6 star in the
field.  All this information comes from Brent Archinal, who is preparing a
book on clusters.
The plotted position for the cluster puts it on the EAST side of the mag 6
star.  I would expect what I saw on the east was just a faint couple of
stars and not the cluster itself.  Megastar shows a small grouping of stars
just west of the mag  6.  I asked Brian if this grouping was included in the
cluster.  I was able to pick out this grouping, but didn't associate it with
6991 due to the listed position.

Here is an observation I made with a 13" f/5.6 Newtonian on
a night I rated 7 out of 10 for seeing and transparency:
NGC 6991  Pretty faint, pretty small, not rich, not compressed,
14 stars resolved at 135X.
Hope that helps;  Steve Coe
P.S.  BTW, if anyone is looking for a scope, I have a 10" f/6
Newtonian on a study German Equatorial Mount for sale, $1400.
