[sac-forum] Re: SAC H400 List

Chris et al, this is just what I was looking for because it is this book from which the SAC Herschel 400 list was derived. I don't know when the changes were made but, perhaps after some discussion, that may be determinable.

It appears the discrepency with these two objects not only includes the Astronomical League but others as well. Others seem to be Skytools from Capellasoft as well as Steven J. O'Mera's "Herschel 400 Observing Guide".

Will keep everyone posted.

Thanks Chris and clear skies to all,
aj

AJ,
I have a copy of the "Observe the Herschel Objects" by the Ancient City Astronomy Club (brown cover with a sketch of Herschel's 20 ftr) with a copyright date of 2005. This lists 1750 but not 7814.
Were you looking for a first or second printing (1980, 1992 respectively)?

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
