I opened up the small dome at about 22:40 BST and used Geraldine to image Mars (at its closest to us this year) and Saturn. Geraldine behaved impeccably with all GOTOs putting the object well within the view with a 28mm eyepiece. However at close-down she insisted in going to 90° Dec when she should go to 0°. I tried rebooting to no avail. Not feeling like troubleshooting at 01:00 I switched her off and manually put her back where she should have been. However I expect her to misbehave next time. The obvious indication was that on power up she displayed 'Align' instead of 'Daylight Saving?'.
I will investigate this when I am able. I finally closed up and departed at 01:30.
