Barlow Lens - DSLR

[Geuse]

I know this is probably a daft question but can someone tell me how i connect my Barlow to my DSLR?

I am guessing the problem lies in the fact that my Barlow is not threaded??

Well if you get a Tele Vue Powermate they can come apart and a t-ring threads right on with the tele vue ring adaptor. Then right into a 1.25 adaptor and onto the 2". Using one right now. Highly recommended.

you will need a nose piece to screw to your camera's T ring
unless your barlow is threaded (the standard SW 2X has this)

You may need another t - ring, the Skywatcer M48 Ring Adaptor is designed to fit their focal reducers. The standard t thread is M42 x 0.75mm, the same as the t threaded 2" nose piece.

Can I ask for what type of imaging attaching a barlow on the DSLR would be beneficial?

[Cornelius Varley]

It depends on the nature of the imaging. For planetary and lunar imaging it would help to improve the image scale. For example

Was taken with a 2x powermate attached to the camera body at primefocus.. Without the powermate at prime focus you get this

The first one was shot using a Samsung NX00 and the other an EOS 400D (similar sized sensor0

Thanks Peter, it's a combination I havent tried yet - but certainly will!

I was advised by FLO to buy one of these:

They said: The only way, if the Barlow has no T thread is to fit this adapter to the T ring on the DSLR, this will give you a push fit into the Barlow.

Ah! That also answers my query in another thread! Thanks Alex :-)
