Sony A7r issue T mount

Postby diripio » Thu Aug 13, 2015 4:40 pm

Hi,

I've recently upgraded my scope to a SW Quattro 8cf. I have also purchased SW f4 aplanatic coma corrector.
My camera is a Sony A7r, full frame, 32mp with an E mount (aka nex mount)

The CC requires an m48 ring adapter. It also needs to be 55mm from the imaging sensor.

I am struggling to find an m48 adapter for an E (nex) mount. SW seem to sell one but
a. Website doesn't say if it's A or E mount (crucial info)
b. No shipping to UK. this was USA,Canada and Germany's website.

Obviously the need of the CC to be 55mm from the sensor negates the use of an m48-m42 step down.

I've had the camera for awhile now as I'm also a keen amateur photographer but would like to use it for astronomy purpose's if I can, also I can't really afford to get a new camera just now.
Would it be possible to get something like this made or has anyone else had the same problem and has a solution.

Any help is appreciated as I am at witts end.
Thanks
