Canon sx420 IS

[Razz]

It'll be quite a while before I attempt astrophotography so this is just a curiousity question at this point. Apparently there is no way to remove the lens on a Canon sx420 to attach the T-ring. At least that's my understanding. Is there any way to attach this camera to a telescope?

Hi Razz

There's an old-school solution involving an adapter that screws into the filter thread on the end of the camera lens.

And an adapter that clamps into the groove of the rubber eyepiece shield of a telescope eyepiece.

This gives you "Eyepiece Projection".

The camera focuses on the image projected by the eyepiece.

Or there are brackets and clamps available to hold the camera lens close to an eyepiece, usually for phones with cameras.

Thanks for the reply. I've seen the phone adapters, I didn't know they also had them for cameras. I'll definitely look into that.

This is called Afocal imaging. Eyepiece projection requires a camera with a detachable lens, the camera body is then attached to the eyepiece and the image from the eyepiece is projected on to the sensor. Hence the name.

You're right, been so long since I used that I was struggling to even remember the name.
