Brill thanks. I have the black 200p too. The only difference in our setup would be the two speed focusser (depth looks pretty similar) and my camera is an entry level pentax but I dont know how much difference that would make.

Out of interest and planning my test run, what sort of FOV do you get with that set up?

This is about the same distance mine comes out

So all these camera t rings are a standard 2 inch thread?

Thus should go straight onto my focusser?

Why do people have issues with focussing a 200p and dslr then?

Yes i use both canon and nikon both rings are different but the threads are the same

I just untread the 1.25 eye piece hold and screws the t ring to the piece which goes into the focuser... But i use the 150p

There are two small grub scews either side of the lock knob that adjust the pressure on the bearings. Try adjusting these  a little bit.

Which ones theres 8 screws

The lock screws is loose

Could anyone help me out please.. Im having a problem with my focuser... Everytime i move the focuser in or out it seems to get stuck...  It will move so far but the stops wondering what it could be

As you look at the photo, which direction is the primary mirror ? 

I dont understand 

The scope is f/5

I'd say that's pretty Bob on. If one wanted to be really picky, the secondary could come down (as you look at the photo) just a smidge. But to be honest you wouldn't notice a great deal of difference. What focal length is your    ota ? If memory serves, it's F6. If that is the case, I'd leave the collimation as is. Just my opinion of course. I'm open to be corrected. 

Al. 

The telescope is f/5... How would i move the secondary down a bit

I follow astrobaby to get this

Skywatcher 150p.... 

Its stressed me out all day been at it since 1 this afternoon trying to get it perfect

Thank you everyone.... Looks like a coma corrected purchase some time in the future
