Connecting camera to telescope

[Dave scutt]

Hi all.

I just purchased a cannon 450d .

What do i need to connect it to me 12" Skywatcher dob.

I've also got a Skywatcher Star Adventurer 2i WiFi Pro on the way , what lenses would be best for the camera for nebula, deep sky.

If that's all you want to do then the simplest way is one of these:

Unscrew the eyepiece adapter from the focuser ring to reveal the male thread.

Lenses: we use 55, 135, 200 and 300mm. All are ok on a sa.  Be warned however that the 'best' ones cost a fortune.

You will need something like this: https://www.firstlightoptics.com/adapters/baader-ultra-short-canon-eos-t-ring.html to attach the camera to the telescope and let you achieve focus without a Barlow.

Something like a 200-300mm lens is great for M42, Andromeda, Pleiades.

For APSC I'd go with Samyang 135 for wide field or Redcat51 for narrower Fov

Trying to mount such on a SWSA brings its own set of issues, you'll need a decent tripod, wedge, polar alignment and some way of finding targets, plus guiding above 135mm
