Is there an after market telescope adapter

[garykahn]

Is there an adapter for Bushnell Telescopes?  I have a Canon A1 adapter but now am looking for a digital adapter for my telescope.  Thanks.

Absolutely. I'm not in the US but there are a few members who can tell you where & what to get but while you wait it might be a good idea to list EXACTLY what you have. I had a T mount to FD adapter that screwed to the lens mount area & only needed the new EOS mount part.

Attaching a camera directly to a telescope (so that the telescope becomes the lens) usually involves two parts, but I'd have to know the exact model of your scope to be more specific.

Since you say that you already have an adapter for your A1, it is likely that what you actually have are two parts that are screwed together.  These are:

1)  T-Mount for your Bushnel telescope. 

This device attaches to the telescope however Bushnel needs it to adapt to the telescope but the key is there's usually a hollow tube of some length (often around 100mm roughly) and it has threads on the back end.  Those threads are a _very_ specific size we call "T-Threads".   These would be "male" T-threads.

2)  T-Adapter (or T-Ring) for your A1 camera.  

This adapter would have "female" T-threads on one side, but would have the Canon mount (breech mount or bayonet mount) for your A1 camera.

If this is what you have (make sure the camera adapting ring can be unscrewed from the T-mount) then all you need is a T-adapter for Canon EOS (T-adapters are sometimes called T-Rings).  

Here's one:

Note that the brand doesn't really matter.  What DOES matter is that it's (a) for Canon EOS mount and (b) it is a T-adapter or T-ring (it must have T-threads... no other size).
