Hi guys..
Im looking around at the moment for a good quality 8~10cm long 1.25" extension tube.. At the moment, I have a pair of gso barlows with their lenses removed that totals 8cm extension, but as they only have one grub screw each, and no compression ring, they are not very solid when attached together... I'll be using it for guiding, so flexture of any kind is going to be a real pain...
I cant seem to find anything, and am starting to think that getting something made is going to be the way to go..
If anyone knows where something like this could be purchased, I'd be stoked to find out!
Cheers.
Alex.
