Bought this for the skywatcher 3/8 stainless Steel tripod. Perfect fit. Have tried it with az5 mount and star adventurer. Both fit perfectly. Makes no difference to vibration when used and helps prevent ota hitting tripod legs. The tube itself is machined alloy and splits apart at the top to reveal the thumbscrew. There is a rubber gasket on top which is very grippy. FLO parcel was well packaged and delivered with DHL within 3days to Northern Ireland 👍

Thanks FLO

Bought to prevent scope hitting tripod when using star adventurer / AzGti on skywatcher tripod.

Easy to fit and solid as a rock.

Coupled with the usual excellent service from FLO, decent price and fast delivery. Next purchase from FLO will be an EQ5 goto Mount.

Very useful accessory to bring the tube to the proper height.

my recent purchase of a Solar Quest head worked well with my Coronado PST but when I tried it with a long refractor it was clear that in the summer the refractor tube would get close to the Skywatcher tripod legs. Secondly it allows for more options for comfortable viewing heights. Very stable in use.
If like me you leave the Solar Quest tracking for long periods (sometimes unattended) the tracking mechanism might not survive if the scope fouls the tripod.

The extension tube is good and solid and I bought it to give clearance for my AZ Gti mount. However I could not work out what the thread was on the mounting hole. It says 3/8. I assumed this meant it needed a 3/8 UNC bolt to fasten to the tripod. But that doesn't seem to be the case. I tried a 3/8 UNC and a 3/8 UNF bolt neither of which fitted. Is it Whitworth or what? I'm assuming that the term 3/8 implied that it's not metric (say 10mm).
Anyway, I ended up using a 8mm bolt and wingnut to fasten it to my tripod and this works fine.

Fits on 3/8 skywatcher mount nicely don't have to extend legs on mount
