After many months of bad luck I finally had everything working, and a night off to boot. It was a night of firsts. First use of the sysnscan Polar alignment feature for long exposure, First use of my new slimline OAG, First time use of My new lodestar and last but not least the first time I've taken and Processed a Ha Picture. All was not uneventful and I discovered far into the picture taking that the prism from the OAG is too close to the edge of the chip so that there was a small shadow on one edge of the pic. But the OAG guiding with the lodestar was magnificent! (pic attached) best thing I ever bought!!
NorthGroup ED127mm APO, QHY10, OAG and Lodestar Guiding. MaximDL, Processed in CCDStack v2, Post in CS6. 13 X 600 sec RGB (OSC), and 6 X 900 sec Ha Bin 2X2.

Suggestions and advice very welcome, thanks for looking.
