Last night was a good opportunity for testing. Although the moon washed out most of the targets I wanted to view it was still a good night for testing my polar alignment skills and GOTO using Starry Night.
The ATEN Usb-to-Serial adapter worked perfectly. I was able to select a target in Starry night and the scope would slew to the target just as it would if using the HC. I could even still use the HC to move around to center the target, and this would be reflected in Starry Night. Very impressed.
The HC did appear Static with RA/DEC information but this didnt bother me one bit.
I'll be out again tonite!
