Hi all. 

I  bought a TOA-130 NFB as a retirement present for myself and now need to get some accessories such as adapters so that I can attach  my DSLR.  (At this stage I am not interested in using extenders, reducers or field flatteners.)  Tak's chart showing the photo/visual system is not clear when it comes to simple prime focus imaging.

 

After looking at the chart showing Tak's photo system, I am starting to wonder with this particular scope that imaging can only be done using extenders, reducers or flatteners.  

 

I have a Tak T mount for the DSLR but am not sure what else I need so that it screws into the end of the focusing tube.  Any advice would be appreciated. 

 

Thanks

Doug

Why not go for a field flattener? The TOA-35FL and the TOA-67fl are good choice.
If you are going to use a full frame dslr the FF is a must have.

Doug,

 

Give the folks at TNR (Tak America) a call. They are very helpful.

You can take pictures without a flattener or reducer, I like to play/test with my scopes in this configuration, this way I can see what the objective is doing without additional glass between it and the camera sensor.

Here is a quick recipe:
  • Get the CA 130 ring TAK #: TKA31202 , you can attach the DSLR wide mount t-ring to this. ( this will be usefull if you get the 35 reducer as it uses the same adapter so no money wasted)
  • Now in order to reach focus you will need extensions : TKA2350 ( you will need a couple of these to come to focus one won't be enough )

And you are ready to go.
Both the reducer and the 67fl are pretty expensive pieces , well worth it in my opinion and the flattener you can use with eyepieces too for some extreme flat fields.

or simply get two inch extensions attach to visual back and get an EOS connector.
if you have a TV powermate it also works with dslr with a single t ring connection you need to order.

Hope this helps
