[sac-forum] Re: SAC H400 List

OK, Here's an interesting twist. I checked in Astrobyte, which is a freeware
program and Uses the SAC DB v7.2. I filtered H400 objects in TAU & PEG and
found that contrary to what AJ shows, Astrobyte has NGC 7814, but NOT NGC
1750, Which is how AJ has it from our DB. 

 

As Chris points out, What's one more object after 400??

Here's an update with additional information.  The differences revolve
around two objects.  NGC1750, an open cluster in Taurus that is on the SAC
list, and NGC7814, a galaxy in Pegasus that is not on the SAC list.

 

In all SAC versions, including the URL below NGC1750 is there but NGC7814
isn't.  On lists that are on my hard drive, and dated 1991, the same holds -
1750 is there 7814 isn't.

 

Anyone have a copy of the early, very early, book on the Herschel 400?  I'm
speaking of the one with brown cover containing a drawing or picture of
Herschel's telescope.  What is status of these two obects and the published
date of the book.  I've just about turned my astronomy stuff downside up
looking for my copy and just can't seem to find it.

 

Any help out there?

 

Thanks and clear skies,

aj

Anyone have an idea when the Herschel 400 list was posted at the URL 

 http://www.saguaroastro.org/content/Herschel-400-objects.htm

 

There seems to be some difference amongst some of the lists on the internet
and I'm trying to see if there is some sort of resolution.  The database
version is 7.2, but is there a big lag in time before the data was posted.
In fact I wasn't aware of the change until today.  Prior to that, I believe,
was just a catalog type of listing and came from a list dated something like
1991.

 

Thanks and clear skies,

aj
