Skywatcher 80ED + ZWO EAF slipping

[FenderGreg]

Hi,

I’ve have a Skywatcher 80ED with the ZWO EAF attached and have so far predominantly used a DSLR.

This whole time I’ve had zero problems but I’ve now just upgraded camera to a QHY 168c which seems a fair bit heavier.

Problem I have now is that the focus tube seems to be just dropping out slowly. I thought the ZWO EAF held on to the focus adjustment to stop slipping? The camera is heavier but surely not now over the weight limit for the focuser?

Anyone else got the 80ED and similar CCD with similar problems? Or found a suitable fix?

If you have the standard 80ED DS Pro focuser then they can slip because they only use friction to connect between the focuser tube and the adjusted rod. You should be able to adjust the focuser to tighten things up a bit and stop the slippage but sometimes the the flat on the focuser tube is slightly bevelled in the middle of the flat and only makes contact on the edges of the flat.

Although this video is 12 years old and for a Newtonian focuser, it's still the same issue.
