Re: Meridian Flip
Gosh, Rob! I have had the same experience as you have... load a "known good model" and ... very weird... the mount will slew to point my scope to the floor while I wonder what button to push to stop

Hi everyone, First of all, I?d like to report that since your help with guiding, the guiding on my G11 has been superb, running close to a half an arc second. Another issue has popped up. For weeks,

Re: RA rate drift (revisited)
Keith I added a third dovetail and adjustable ring that holds the extension tube tightly. I could have put it on the focuser directly, but went with the extension tube to make the third ring as close

Re: RA rate drift (revisited)
Keith, I would suggest, if you haven't already done it, that you mount the guide scope directly onto the G-11 rigidly, not with the C8 involved at all. Simplify the rig as much as possible and then

The 4¡±/minute drift rate is kind of close to the difference between sidereal and solar rates. That could explain being slow, but wouldn¡¯t explain being fast on the other side. -Les
