Canon 400D on Newtonian Reflector

[EA2007]

Hey kids,

Last summer I had trouble reaching focus when I had my Olympus E-400 at prime focus on my 8"Reflector (Celestron Strahopper Series Newtonian Reflector). There was not enough down turn on the focusing knob, so the camera was hitting the focusing unit

If I were to use a Canon 400D and a Skywatcher Explorer 200p would I have the same problem achieving focus, if so what equipment would I need to solve the problem?

I have the Explorer 200 and the 400D and have no problems achieving focus.

You just unscrew the 1.25" eyepiece adapter which reveals a direct SLR attachment. Onto this you screw the T-mount which you can buy from First Light Optics. The T-mount also attaches to the 400D.

Thats it - all you need to take great shots.

I would recommend the remote control shutter release - £14.99 from Argos as this will save you from having to touch the camera to end the shot.

Cheers.

Do you mean t-mount or t-ring?

I have a universal t-mount which is plain metal: http://www.telescopeplanet.co.uk/ViewProdDetails.asp?name=Celestron%20Universal%20T-Adapter%2031.7mm&prod_code=PON06B000022

But I also know you can get screw-in t-mounts:http://www.celestron.com/c2/product.php?CatID=50&ProdID=363,

is yours the screw in type?

He means the Canon EOS T-ring (converts bayonet fitting to a standard screw fitting for most astro adaptors). The 1.25" adaptor that was also mentioned only comes with skywatcher telescopes (the eyepiece holder doubles up as a low profile SLR adaptor). A word of warning, with a lot of the 'off the shelf' standard adaptors, you cannot achieve enough inward focus with DSLR's and Newts. You have to make sure you get a low profile adaptor (much like the skywatcher one's). As I used my skywatcher one, I don't know where you would buy one from so apologies for no link .
