Powermate 2x owners

[Owmuchonomy]

I was thinking of obtaining a Powermate 2x to attach to my SCT 9.25" for the purpose of planetary imaging. Can you advise what is under the 1.25"  top attachment? Is it a thread suitable to attach a T ring? If so what is the thread size? I have 42 and 48mm t rings plus other options and wondered if these would fit.

I owned one of these, Chris, and it did not have a T Ring. I think you have to buy one of these, but I am not sure which one.

I have one of these, acquired a few years ago, when I had ambitions of delving into imaging. Apparently the top half of the barrel of the lens unscrews to enable the special T- ring adapter to fit the Powermate lens assembly, through an internal thread on one side of the T-ring adapter which slips over the top of the lens so they can be screwed together, it is only necessary then to screw the camera T-ring, which I presume will be the standard M42 into the T-ring adapter. The one you want for the X2 Powermate, is the PTR-2200. Hope this is not too confusing

Yes I have got both parts of that kit, but never actually used the extension part.

I'm hoping its an M48 or M42 thread. I'd rather not buy yet another adapter.  So if anyone can confirm that? Thanks.

On the 2" version it unscrews and you have to buy the adapter that screws on.

Oh, I see, it detaches below the EP barrel.  More expense! Thanks Dave.

Just to confirm the size for you, I have put a vernier gauge across the T ring camera thread part and it measures 41.95 mm, so it is fair to assume it is the standard 42mm T ring male fitting. New, I think the PTR-2200 costs something over £30 HTH
