Why is this the only image I can get?

Hi,

I have attached my Canon DSLR to Sywatcher 200p but this is the only thing it can see. I cant see anything else when the DSLR is attached using the T-Adaptor etc. Whats causing this?

Is this a problem with the secondary mirror needing collimating? (guesing here)

not enough inward travel on the focuser. you need to get the camera chip close to the secondary thats why people get low profile crayfords

A friend suggested inseting a barlow? I tried that but still couldnt get anything.

if you unscrew the 1.25 eyepiece adapter off the focuser it leaves a thread that will screw into your t adaptor you should get focus then. thats how i got mine to focus

thats still not enough i got http://www.teleskop-express.de/shop/product_info.php/language/en/info/p4018_2--adapter-with-brass-compression-ring-for-Skywatcher-Newtonians.html with http://www.teleskop-express.de/shop/product_info.php/info/p586_2--1-25--reducer-with-many-additional-functions.html

that way i have still about 5mm left when focused

I have exactly same scope as you
