Quote:No turning on or off or redoing the go-to alignment will help his problem. If I read his post correctly, he was showing lots of declination drift while PHD was guiding. That means a problem with polar alignment. Be sure to use a star to the south, one not too high. 30-degrees or so, for ASPA.
Quote:I never understand the need to power down the mount after any kind of calibration or polar alignment. If you need to redo the alignment, simply slew to a star, press "ALIGN" button and follow the on screen instructions. It's a lot faster and just as accurate than to power down the mount. It's absolutely unnecessary to power down the mount to redo or check the alignment.Peter
Quote:Ok I think I have found a solution. My goggle fu was great tonight! Sine of these mounts were having issues guiding in dec. Example would be my phd guide graph. After searching several old threads frim different sources I stumbled in a topic that celestron was making a firmware solution for this exact problem. Then I thought, hey its after midnight might as well try and see if there was a update and..... yep. I updated my firmware and re did a rough polar alignment through my polar scope. Re dud the alignment and fired up phd. At this point I just wanted to see how the graph was doing. Even though my alignment was off they both tracked decent. They were not running on the center line but I could tell just from the graph that it was improving. If I would of done a proper polar align I'm sure this solved my issue. If someone else has had this issue please chime in and tell me what you did to fix this. Im about 95 percent sure tomorrow night will be good.

Quote:You must be using the AT8IN?If so.. then yes 60 seconds unguided is out of reach.If you're absolutely sure your polar alignment is dead-on (i.e. no drift in DEC if you turn off DEC guiding in PHD) then you're hitting the large periodic error of the CGEM and CGEM DX.Try doing a PEC training. This still won't help a lot of your 8/3 error is too large.
