Cool!... I did one of these with the 12" LX200 and one with the 90mm.. Now that I know I can do it with the 90mm, I am keen to do more.. Of course I have a meeting tonight and school, so tomorrow night is my next night.. As I told Ted in a separate email, where I sent the file he requested, I had entered an observation and then discovered the ability to measure from a camera.. Then I found my default position was not as accurate as I have it from Occultations.. Etc.. I have deleted and redone the Obs twice already.. Is there a way to edit observations in ObsReduce??

Congratulations on your first positional observations. Comparing against elements less than 12 h old, reveals the following residuals: Residuals -------------------------------------------- Total Time xtrack RA Dec Object Date UTC deg s deg deg deg 91050A 2008 3 24 03:10:32.91 0.2464 0.1348 0.2406 0.4542 -0.1112 06044A 2008 3 24 04:42:21.181 0.0300 0.1067 0.0126 -0.0193 0.0096 A good first effort, especially 06044A. Your 06044A cross-track residual of 0.01 deg is excellent, similar to that routinely achieved by the best observers. Your 91055A obs has a large cross-track error. If you will e-mail me your ObsReduce details file (i.e. the *.det file), and if possible the video frame you reduced, I may be able to spot the problem.
