Yes how indeed?

I saw mention in an earlier post of the guide rate setting in EQMOD being low at 0.2.... what should that setting be ? So far im going with the Trevor Jones school of thought and not stressing too much about the numbers but would like to get a stable flat saw tooth rather than a sine wave saw tooth hunting above and below the centre axis. Been happy with the images so far but its nice to know what settings to use to start out with.

So I had a look for myself and took the cover off the DEC motor.  

The gears had a fair bit of play so I adjusted the screws and nudged things about a bit and now it seems to have a fair bit less play.

Going to have to wait to Wednesday by the looks of it for a clear night to see if this actually makes any difference though

It did have a lot of dec backlash when I first got it but I reduced this without too much trouble.

How did you do this?

Managed to fix it. The rubber end cap thing had just slid partially off the metal rod so the whole thing was "falling" into the scope. Once I put the end cap back on properly it was all working fine and not moving in/out.  

Essentially, the metal rod is supposed to be "fully" pulled out, then the rubber end cap needs pushing all the way in so it's touching the o-ring seal, this stops the whole thing from moving back in.

I can't see the video I''m afraid - the message suggests that the file is corrupt ?

 

I've put a youtube link in the post, hopefully that one works

As you can see in the attached video, the focuser on my mak slides in and out. This can happen even if not pulled on - it can slide in/out just due to gravity. Anyone know how to fix this?
