Dual speed focuser repair?

[Barry-W-Fenner]

Hi all,

Just wondered if I could have some assistance with my Sky Watcher dual speed focuser. Last night while setting up the 300p I accidentally and unfortunately hit the 1.25 to 2" adapter on a door frame. The adapter appears to be ok, However the draw tube is has now gone very loose in the focuser and can be moved very easily by hand.. It doesn't feel secure at all. This brought an end to my "session" and I could have kicked myself as I have managed to stay accident free with my scopes until now.

I checked all the small grub screws by the focuser control nobs and they are all tight, Nothing seems to have come loose. Anyone know of a way to tighten the draw tube back up that I can try?

 

Thank you

For reference I have added a pic which shows the focuser I have, Its the normal sky watcher model not the low profile.

If that's the sort with the thin aluminium walled focuser tube then you've probably stuck a dent in the tube wall. It may be possible to get it straightened out but given the tolerances it'll possibly never be the same
