Comments on: Terzan 11 Globular Cluster in Sagittarius http://www.skythisweek.com/2007/09/12/terzan-11-globular-cluster-in-sagittarius/ Occasional observations of an amateur astronomer Mon, 28 Sep 2009 14:20:48 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: Vern http://www.skythisweek.com/2007/09/12/terzan-11-globular-cluster-in-sagittarius/comment-page-1/#comment-943 Vern Tue, 25 Aug 2009 18:16:53 +0000 http://www.raben.com/weblog/2007/09/12/terzan-11-globular-cluster-in-sagittarius/#comment-943 You might take a look at Barbara Wilson's write up regarding Terzan 11 at http://www.astronomy-mall.com/Adventures.In.Deep.Space/obscure.htm She discusses the confusion regarding this object as well. I originally searched for Terzan 11 on the DSS - 'The Digitized Sky Survey' website and retrieved an image of the region. I used it to confirm that the star field matched with what I was seeing on the monitor when I obtained the image above. I repeated that check this morning using a DSS image of the region. The DSS coordinates for Terzan 11 match those that Barbara quotes. These are also the coordinates for Terzan 11 used in the Astroleague's Globular cluster book. Based on this, I still believe the image is correctly labeled as Terzan 11. As I understand it: The globular which was named Terzan 11 was found to be the same as Terzan 5, so it was renamed Terzan 5. Terzan 12 was then renamed to be Terzan 11. IE that is the globular pictured above, if I follow Barbara's article correctly.

Terzan 11 was mis identified...it was actually a rediscovery of Terzan 5. Great work with and 11 inch scope!!! By the way Terzan 11 is actually Terzan 5.

Its nice to see that these super faint globulars can be imaged with medium size scopes. No easy feat!!! Again, great work. Tony Hell Vern, great work!

Again, great work.
