After 3 months of CCDBot development I decided it was finally time to see if the precision slews actually worked in the real world. I was very happy to see test results ranging from 4 to 22 arcseconds of final pointing error for several objects in different parts of the sky. I also redid my user interface as a tabbed interface. This gives CCDBot a very small foot print. The application form changes size depending on which tab you select. The sizes range from 717,690 (Session Planner) down to 685, 401 (Log Viewer). I also tested the "Image Scale Wizard" which worked fine with the small exception of forgetting to divide the image scale by 3 for the 3 bin image! :-) Here's a snip of the log file... 18:25:11 CCDBot Session Start 18:28:58 ****************************************************************************************************** 18:28:58 ****************************************************************************************************** 18:28:58 Starting Session Review 18:28:58 ****************************************************************************************************** 18:28:58 ****************************************************************************************************** 18:28:58 Connecting Telescope... 18:28:58 Session will start at: 5:36:43 PM 18:28:58 Session will stop at: 5:51:55 AM 18:28:58 18:28:58 Session looks good, please click the continue button to start the current plan... 18:28:58 Session Summary M45 1 Exp(s) 2x2 Bin Blue 60s 18:29:01 Continuing with the planned session... 18:29:02 CCDBot Beginning Planned Session 18:29:02 Session will start at: 12/20/2014 5:36:43 PM 18:29:02 Session will stop at: 12/21/2014 5:51:55 AM 18:29:03 Target M45 is -186 arcminutes East of the meridian... 18:29:03 M45 Altitude is 48.3277818869327 Degrees... 18:29:03 Starting Precision Slew to target M45 18:29:03 Beginning Precision Slew to: 03 47 10, +24 16 36 18:29:04 18:29:04 Slewing Telescope 18:29:28 Taking First Precision Slew Correction Exposure... 18:29:54 Sync Image: C:\Program Files (x86)\Owl Mountain Software\CCDBot\sync\C:\Program Files (x86)\Owl Mountain Software\CCDBot\sync\\Red.00000008.ASCOM_target.FIT 18:29:54 Plate Solving... 18:29:57 Plate Solved Successfully 18:29:57 Initial Slew Result is: 03 46 00, +24 15 00 18:29:57 Position Angle: 269.717140180177 18:29:57 RA Undershoot Error (arcmins/arcsecs): -2.3 / 138 18:29:57 Dec Undershoot Error (arcmins)/arcsecs): -3.2 / 192 18:29:57 Slewing to corrected coordinates: 03 48 20, +24 18 12 18:29:58 Slewing Telescope 18:30:02 Checking Final Slew Results... 18:30:13 Sync Image: C:\Program Files (x86)\Owl Mountain Software\CCDBot\sync\C:\Program Files (x86)\Owl Mountain Software\CCDBot\sync\\Red.00000009.ASCOM_target.FIT 18:30:13 Solving Plate...
