Tube ring(s) 150mm, only one needed

[bojan]

I need only one.. but will take both.

It's a shame that no one can 3d print one for you.

Hmmmm..
Now you gave me a material to think about...
I could try to print the spacer-pad, and use Flexy Clamp.. like on attachment.
BTW, I need it for this lens, to have stronger attachment to vixen-style dovetail bar (and for accessories).

Hi Bojan,

Did you get any direct replies? I'm after two Celestron 150mm rings.

Hi Andrew, not a single one..

Be careful, it seems 150mm rings (for tube with outer diameter 150mm) are not standard.
And, it seems Skywatcher is even labeling them wrongly: Andrew from Bintel ordered a pair for me and when they arrived we discovered they were made to accomodate 180mm dia tube.. (for 150mm mirror ?? this is just a wild assumption to explain the discrepancy)
