Hi, I was out earlier this evening and managed to pop off a few shots. Using an LXD75, phd guiding(PEC turned off as was suggested) and a meade 8" sct with piggybacked 80ED. Everything seemed to work great for the first minute and a half until I noticed after about 200 seconds the guidestar seemed to jump and ofcourse my photo has a tiny secondary star next to large stars. After a few hours of realigning and making sure everything was balanced, leveled, etc. I packed it in. No matter what I tried I still got those tiny seconary stars next to more prominent ones. I was getting tired and dew was coming for me as well sad Here is a photo of what I am experiencing. It almost seems as though there is a burr on one of the gears that hits every 200 seconds. Anyone have any suggestions?
