Quote:If you mean "level it and point it north" mode, never tried it. I can't see Polaris from my usual observing location. Plus, the two star setup is just so easy.

Quote:Check to see if the right side bearing on the OTA is rubbing agaqinst the right side panel. There should be a small gap of a couple millimeters at least. If it is rubbing, that could be causing some stiction, resulting in jumpy tracking. Some lithium grease or graphite powder between the two parts might solve it, or you could add a thin shim (maybe 1/16") between where the right side panel attaches to the front panel, as this would move the right side panel slightly outward, creating the needed gap.
Quote:I may have noticed this for the first time the other night. The conditions were:a) Viewing an object near zenith.b) High magnificationc) A heavy EP installedd) Scope not sitting on level groundIn particular, (d) is something that I had not done before. I was setup on the sidewalk in the front yard and we live on a reasonably steep grade. Based on the fact that I have not noticed this before, but have viewed with at least two of the other three variables in place simultaneously, my current hypothesis is that the sloping ground was a big contributor.
Quote:Would like to get some input from owners of the Orion XTg goto dobs, if you've had issues with motor induced vibrations causing image "bounce", especially with high power viewing, as mentioned in the S&T test report?Also, has goto accuracy been satisfactory?
Dan Orion XT8g If your dob isn't broke, fix it anyway. Don't tell me what I want to hear, tell me the truth.
Quote:The fan shouldn't make the view jittery either. I can't tell when my fan is running. Orion needs to take that one back and replace it. There's something seriously wrong with it that isn't wrong with the others.
Quote:I am always amazed at how smoothly my XT10G tracks, even at high powers. I always expect to see something from the motors but I never do. On the other hand, when I don't have the tracking on, and am trying to nudge the thing, that's when the view bounces all over the place.
