T adapter question???

[Phantom 6sic6]

Ok I just picked up a Canon t3, I know I need a T ring and T adapter to attach to my 6se but there are so many different types! I'm definitely going to want one that can have eyepieces inserted into but my question is some are stationary and some are adjustable. What is the advantage and disadvantages to stationary or adjustable?

[Cornelius Varley]

The adjustable ones are usually used for eyepiece projection photography. The greater the distance between the eyepiece and the focal plane of the camera the greater the magnification.

IMHO I'd start with the basic 1.25" to T thread adaptor to mount in the scope. You'll also need the T2 (T thread to Canon EOS) adaptor.

This will allow you to image at "prime focus".

I would be inclined to get a Barlow with T adapter like this http://www.rothervalleyoptics.co.uk/celestron-x2-barlow-lens-with-t-adaptor-125.html but you will still need a T ring to fit the camera. It is possible to remove the lens from these adapters so it just becomes a T adapter with no additional magnification.

I too would start off with the basic prime focus one easier to use and sharper images, the adjustable types are generally used with a barlow the distance from barlow to camera can be increased and this increases the effective magnification.

Keep it plain and simple and repeatable once you get the hang of it then play around with barlows, projection , and anything else that's on the market.......

thanks for the advice I did order a adjustable one http://www.ebay.com/itm/1-25-Variable-Projection-Camera-Adapter-Telescope-for-Cannon-DSLR-Camera-EOS-/251294859302?pt=LH_DefaultDomain_0&hash=item3a82574026 and I already have a standard celestron t adaptor now ill have many options. I also ordered a sheet of solar film!!

That will only work by having en eyepiece that fits inside the part you have just bought.

This becomes Eyepiece projection imaging, high power for the moon and planets etc. I have done this type of photography on the moon and Jupiter. The hardest thing with eyepiece projection is that the FOV is very small and getting the planet into the chip is often rather difficult.

It's fun with the moon though and fairly easy
