Skywatcher Skymax 127 MAK Focuser slides out

[JoeRPatrick]

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?

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

Hi there I'm not familiar with your scope but this link on the Cloudy Nights forum might help.

If its within its warranty I'd send it back, but if not, I'd remove the back cell from the tube and take a look. Avoid touching the mirror and make a note of which screw hole is which for when you put it back together. The problem is likely to be a clip, split pin or nut that's come loose and become detached. It's very likely a problem that's easily resolvable .

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.
