What's New with RTGUI

What's New with RTGUI+S and its Related Files


 
2009

Feb. 18, 2009: Release 8.4

 
2008

Aug. 14: New catalogs: Sharpless catalog of H II objects (mostly in the northern sky), and the RCW catalog of H-alpha objects (mostly in the southern sky). These are emission nebulae, representing star forming regions, and are best observed using a nebular filter. Catalogs are in theFiles->Catalogs area of the Yahoo Group for RTGUI.

May 8: Release 8.3

Bug fix: calculated transit altitudes for moon, sun, and planets were incorrect (catalog objects were OK).

New Feature: "Maximum Altitude" is now an option in the Search Wizard. Use this option when you do not wish to observe objects close to the zenith. Some scopes (and some peoples' necks) would prefer not to be looking directly overhead. The default value is 90 degrees, so if you ignore this field it will have no effect.

April 2: Release 8.2.
Disabled "OK" button on Comet/Asteroid form after it's pressed. (Pressing twice caused program to hang.)

Changed comet/asteroid position request to include current hour as start time. (Apparently the MPE Center changed it so that the current hour is not, by default, included, causing "load error" for first 30 minutes of each hour.)

2007

July 19: Release 8.1.
Literals for Asteroid and Comet names: Because the Minor Planet and Comet Ephemeris database is case-sensitive (and in a non-intuitive way!), RTGUI reformats all names entered to a format that has been found to work. However, to allow for unusual cases where RTGUI's reformatting may not be correct, "names entered inside quotes" will be presented to the database exactly as typed. Fixed name-formatting bug for comets having two letters in their designation (Example: C/2006 VZ13). Fixed problem in deleting obsolete transient file. (File could be deleted using "Delete" button, but auto-delete and update was not working). Fixed bug where the existence of a previous 60-day positions' file for an asteroid prevented Near Earth Object positions (24 hours) from being downloaded for the same object.
Additional features: Commas now added to separate the different fields in file MATCHES.TXT. This allows the data generated to be imported easily into spreadsheets such as Excel. A few objects in FULL.RTG had commas in the name field; these have been replaced with semicolons. (Commas in a name field in a catalog will mess up the columns in the spreadsheet.)
Name of current location file (default:rtgui.hom) is now displayed in the bottom left corner, to help you remember which location you have loaded. Some revisions to "Best of Sky" double stars (promotions and demotions).

April 20: Updates to Scripting Document concerning use of of Transient Catalogs: Explains how to use RTGUI scripts to position telescope to comets or asteroids. (Brings the Scripting documentation up-to-date for the new features for Release 8.) See http://scripting.rtgui.com/ .
