Barlow and T-ring for a DSLR.

[Grog]

I have been reading up on this equipment. I own a 3x Barlow. I have seen barlows that can attack to a t-ring that attaches to a DSLR. My Barlow doesn't look like it will screw on so to avoid buying a new suitable barlow, is there a way to connect an original barlow to a t-ring?

I own a Canon DSLR as I know that can make a difference with t-rings. (so I have read)

Also, I have some filters including a moon filter. I take it there is some way of screwing this on some where when using a t-ring? Just thought of that.

Thanks.

I think you are going to have to get a Barlow that already has the thread to accept a T ring, it will also be threaded to accept a Moon filter. A 2x Barlow would probably be a better bet, you could sell the 3x to help fund it.

This is the adapter you need http://www.firstlightoptics.com/adapters/flo-125-inch-t-mount-camera-adapter.html . The threaded end screws into the t -ring and the other end pops into the barlow just like an eyepiece.

Thank you both. Cornelius, can this t-mount fit eye pieces and barlows?

The nosepiece adapter is for barlows or focusers, not for eyepieces.

For eyepieces you need a projection eyepiece adaptor. You cam get them from telescope house , for the revelation one, for around £20 delivered. This has the thread for your t-ring, will take some ep's, and will work in a Barlow (like you already have presumably).
