Hi Arne,

Let me have a 'rummage around' in my box of bits. I'm going out very shortly for a relatives birthday party and won't be back till late, it may be monday before I find out, but I will.

Thanks

Mark

Hi Arne,

Sorry, all have gone now. I only have one for myself and want to keep it just incase I ever come by a SM60 etalon to use on my SM90.

Thanks for asking though.

Mark

These were originally made by astro engineering here in the UK. Not aware of any other sources, only possible other would be TS Service in Germany. Maybe precise parts us the USA? Let us know if you get anywhere with either.

Will do! Thanks!

Since I have a 60mm single stack this could sort of give me not only a cheap way to double stack my 90 but also make the investment good for both scopes.

Do you remember the thread sizes for this adapter? I'd like to buy one in case you decide to sell your last one. Thanks.

I think the sm60 is m72 or m77 thread. I would have to measure it to be sure.
