How to connect camera to 130pds


Recommended Posts

A comma corrector may well be a very useful thing, but they are a bit expensive.

This one is cheaper : http://www.telescopehouse.com/acatalog/Revelation-2--Coma-Corrector-for-Newtonian-Telescopes.html

But they aren't ABSOLUTELY required to connect your camera.  You will ALSO need a T- Adaptor though to go with the T-Ring.  Can be found here:

https://www.firstlightoptics.com/adapters/astro-essentials-1-25-inch-t-mount-camera-nosepiece-adapter.html  (£17)

or here : 

http://www.telescopehouse.com/acatalog/Revelation_T_Adaptor_1_25__-1.html (£14)

Or in 2" form : 

http://www.telescopehouse.com/acatalog/Revelation_T_Adaptor_2__-1.html (£16)

And a cheaper T-Ring here :

http://www.telescopehouse.com/acatalog/Canon_EOS_T_Ring-1.html (£10)

That's really the minimum you will need.

If you also want to use your eyepieces to increase magnification when using your camera, you will also need something like a projection eyepiece adaptor :

Or you could get a barlow for increased magnification (actually focal length)...

*Note that the T-Adaptor wont strictly be necessary if you do decide to use a Coma Corrector or projection EP adaptor or some barlows (not all barlows though, so check), as they will already have 1 1/4" or 2" nose pieces with the T thread.  And, in fact, the projection EP adaptor comes with the 1 1/4" T-Adaptor anyway, so probably worth picking one of those up anyway.

I would advise against buying a cheap £10 T-ring. I know a few people who did and had to buy another one due to loose fit, wobbling issues etc. Might be worth getting the one offered by FLO or Baader Protective. Much better quality.

Never had a problem with mine.  Fits snug as a glove, and can't imagine telescope house selling sub-par gear.  Everything I have had off them has been excellent.

But yeah, could spend twice as much on the T-ring from Flo.  It may or may not be any better quality.

I did this for the first time a few days ago (Canon 1000D to a 130pds) and needed a T-ring and a threaded 1.25" barlow - FLO gave me some very good advice and I'm sure would do the same for you :)

All the above are correct, but forget to mention that this is prime-focus...

...if you want afocal, (ie using an eyepiece), then you will need an eyepiece projection unit, (epu), too, plus the T-ring.

You will not be able to get enough inward focus with a 1000d. You will need to use a Barlow lens.

I found that too.  Until I removed the spacer that allows you to use EP's for visual.  Then it was all good.
