Quote:My RA actually is tighter than DEC - due to all the DEC backlash, stiction, etc. And I don't see how I can guide tighter in RA considering my RA guide speed is at 0.3X already.Could the RA drift be due to altitude polar misalignment? I will admit my polar alignment is... indifferent at best (did not do a drift align).
Quote:3. Know that your maximum exposure is related to how well you polar aligned. You need to be closer than 2 minutes from the pole to get 10 minute or longer exposures.

Quote:Hi OrlyGood to hear you are making progress, the OAG removes any problem of flex (if the OAG is reasonably mounted). How long is the exposure time of your guide camera? I use 2s - 4s to make sure I am not chasing the seeing, this with PHD on LFE Photo.That the DEC is not acting frequently is a good sign!What is your exact motor, gear configuration? Any play in one of the components. How is the gear mesh adjusted on your AP600 mount?best regardsChrisBTW Just finished watching the F1 in Singapore...
