Hi all, I have an issue when using prime focus photography with my telescope, I use a full size DSLR Sony A200 attached directly to my Skywatcher 150P on a EQ3-2 Motorised mount, I cant seem to balance the scope when the camera is attached it seems too heavy especialy when using the 4x Barlow, so just the shutter of the camera causes a slight telescope shake, even noticable on a bright moon 1/200th shutter speed, the view is sharp through the viewfinder but images are blurred when on PC, how do you guys prevent this, Ive even tried to attach my camera tripod to the camera but this makes it difficult to adjust aim on the scope? any ideas welcome thanks.

Does it need an extra counterweight? or is it the length of the a200 plus dslr? if that is the case then perhaps it's the focus tube? On the smaller scopes this is sometimes a problem and may need upgrading to take the extra weight hanging of it.

This was my set up last night on the 200p, although it has a very good quality focus tube : http://www.flickr.com/photos/raygil/6847296673/

Thats how far my camera is from my scope, Ive got a 6" on a EQ3 you use a8" on a EQ5 probably a bit more sturdy, Ill just have to experiment next time I have a clear night.

Well it's probably the focus tube, you can upgrade it, to a sturdier one! That may be the way forward.

The focuser is the same 2" Skywatcher as yours with a 1.25" eypiece adapter & a 2x or 4x barlow, its all a nice tight fit in the sockets, I can see the scope shake when the shutter fires, I need to stop this movement, i might try to rotate the camera to see if the shake is directional.:)
