Can someone who owns this tube give me a close up of the focuser connections 

 

It seems to offer a variety of screw threads from 90mm down 

 

I am interested in getting a flattener for it (not full frame) and trying to work out what fits!

 

ta!

132 (which I don't see listed) or 130 (which I own)?

 

I use this flattener, I'm a big believer in using the flattener the manufacturer/vendor recommends.  It screws directly into the end of the focuser, which is as direct a connection to the scope as you can get.

According to TS,  two refractors are using this 3.7" focuser, one 130 and one 152 (there is no 132):

https://www.teleskop...PA-focuser.html

 

Connection threads at camera side: M100x1, M92x1 and M68x1 thread (female)

Connection at the telescope side: M117x1 thread (female) with rotation

 

TS recommend the TSFlat3 flattener with M92x1 thread (male) connection at telescope side.

yes - bad fingers - 130mm - that should be whats arriving :) 

 

I'm not doing full frame so wondered if there was other options 

 

not the cheapest option and I have he 2.5" flattener hence asking about the threads 

 

:)

Option is to use various thread reducers.  This mounts the TS 2.5 flattener/reducer (I didn't want to reduce the focal length).

for the sake of 30 odd eu I might try that and my TSFLAT2,5

 

as I am not full frame it might well work decently vs buying a new flattener

 

I have various reducers but will have a look at the matching reducer

Doesn't your TS Flat 2.5 already have a m68x1 on the focuser side?
