I think I remember seeing some posts from TP members on astrophotography, I don't dabble in stargazing so I'm quite ignorant on the subject, however my 30 yr old son has recently caught the stargazing bug in a big way and asked if I could get some info from TP if possible.

He has a Skywatcher Explorer 130 telescope, he has asked me to find out what he would need to connect his DSLR to the telescope.
He currently has a Canon EOS 300D, kit lens 18-55mm, Tamoron 28-75mm 2.8 and a Sigma 75-300 F4.5-5.6 APO lens.

Does the adapter connect the camera body to the telescope or is it camera and lens to telescope ?

What adapter would he be looking for for the above camera/lens/telescope? if you have a link to the required adapter it would be much appreciated.

Thanks
 
You will need a T-Ring, as indicated above, and an adaptor http://www.firstlightoptics.com/adaptors/flo-125-inch-t-mount-camera-adapter.html to attach it to your telescope.

Be aware that you will probably not be able to achieve focus with a combination of DSLR and a reflector telescope like the Explorer 130 (not enough inward travel on the telescope focuser). One way round it is to attach the DSLR to a barlow lens (not ideal as it increases the focal ratio, but it works to a degree), the other is to move the telescope main mirror further up the tube, not for the faint hearted!


Cheers
