telescope to camera....or vice versa...

Postby jgolden104@comcast.net on Sun Mar 29, 2009 2:08 am

I just purchased a Sony DSC-H50 Advanced point and shoot. I believe it is a 58mm lens, that is threaded for adaptors, and hoods, Etc., so I'm wondering if anyone knows if someone makes an adaptor that can be used with a telescope. And would the adaptor work with any telescope, or what specs on the scope would I look for to be able to use with the camera./adaptor. I'm new to this, so bear with me. Thank you.

Hi

That TYPE of camera is not typically used for serious astrophotography because, like all point and shoots, it is limited in the length of time the shutter can stay open. Exposures in astrophotgraphy run much longer than what you get in any pont and shoot. We are sometinmes talking hours and, at the very least a portion of an hour. Your Sony has a max exposure of only 30 seconds. This means you will be limited to very short exposures of the moon and planets at low magnifications.

The bigger problem is getting an adapter, since adapters for telescopes are for SLRs - cameras with remvoable lenses. On that camera, you are not going to find an adapter or, at least, we don't carry such a thing. Sorry.

You can add an SLR to almost any telescope, but that does not automatically make the combination suitable for astrophotography. You also have to consider the mount and its features very carefully. You will need a model which offers motorized and equatorial tracking capability or that can modified to do so.

For the basics on astrophotography, see my short article,

Thank you for the information. I was wondering about one other possibility....I saw a mount designed to hold the camera for a shot through the view finder of the telescope. Without acutually connecting to it. I'm sure this is not for professionals, but it would work for me I think, am I correct?
