Canon dSLR to telescope help

[milkyjoe]

Hi.

I've recently purchased a Canon 1000d camera and would like to attach it to my telescope, but not sure what I need. Can anyone help please and suggest site(s) to buy the bits?

I have a 4" Sky-Watcher ST102 telescope with a 1.25" eye piece holder.

Thanks.

Richard.

Although not ideal a Canon EOS T-ring and T -1.25" adpator will get you started... to minimise vignetting you want to maximise the clear aperture through the adpators.

IIRC doesnt the ST102 have a dual fit focuser and direct DSL connection?

In which case you have a few more options...

You may also need about 50mm of extension tube in there somewhere to compensate for the removal of the diagonal

Give the guys at FLO a ring they should be able to sort you out with the bits you need...

I bought the EOS T-Ring and a T adaptor from Amazon & Ebay respectively. By comparing the two places I saved a couple of quid.

Would a 2x Barlow have the same effect as a Canon EF 2x extender?

Just about...

I use a Canon 5D Mk II and before that a Canon 40D coupled with a T-mount and a 40mm extension tube prior to a Baader Hyperion zoom. That extension tube was essential to bring the focussing range within reach using a SolarMax 60mm refractor.

Visually while attempting focus I still get those dreaded "Newton's Rings" but these are not apparant on the photographs - unlike trying without the 40mm extension ring.

Hope this helps :-)

Hello Steve, I see you have got a Coronado 60 mm Double Stack and you see Newton's rings visually. Could you say - is your Double Stack made at Coronado or you made it by yourself using 2 Coronado filters?

I tried to make Double Stack using SM60, a refraktor 75/600 and PST.

The picture changed dramatically considering details on Sun (comparing to single SM60), but these Newton's rings ... it was terrible.

I have decided I need a factory-made Double Stack, however, I have some doubts now.
