ST80 Draw-tube Clamp Replacement

[inedible_hulk]

There’s a lot of good posts on here, the other place, and YouTube on modding and upgrading the humble ST80. However, I am finding it difficult to find anyone who has just upgraded the clamp at the end of the focuser draw-tube (it just unscrews).

The stock one is rubbish and once I have a diagonal and my Baader zoom attached, things can seem quite precarious. Does anyone know of a suitable replacement, or even just the spec of the thread on the draw-tube please?

try replacing the thumb screws with M4 stainless grub screws 10mm long (Ebay). Don't go mad when tightening them with a hex key. For convenience you can also get long handle keys with a Tee grip which is easier than the conventional 90 degree keys

On the off chance someone with the same question stumbles upon this thread, the end of the diagonal / eyepiece clamp is T2 and the Baader Ultrashort 1¼" / T-2 Eyepiece Clamp makes a nice secure upgrade.
