Re: Very odd RA guiding issue

Hello Mike, Do you power off your CCD between sessions or keep it on all the time? I had some odd guiding issues and it seems that they were CCD related. I kept my SBIG powered on all the time

Re: what grease to use?

At those temps it's best to use no lubricant/grease at all. Typically 'machines' that have gears operate best at very cold temperatures with no lubrication. Of course, this means removing whatever

Re: Very odd RA guiding issue

You are not the only one who has run into this. I recently helped an advanced amateur that had intermittent guiding problems with a high end RC scope on his 1200 mount. I had him check everything,
