But there doesn't seem like there's any way of adjusting tilt with this focuser - did yours allow this sort of adjustment?

Hmmm I thought this was a selling point of the focusors. I will look next time I am down at Clayton. Maybe I was mistaken?

Looks like there would be no problem with the Newt version as it has a mounting plate with adjustable screws for tilt - but the refractor/RC version just has an adapter ring with 3 small screws with which to attach focuser to the RC's extension rings. No obvious adjustment mechanism!

Perhaps the tilt in the image represents mis-collimation of the primary??

Wow!!! That is awesome. This is the stuff I really want to do, I am currently in the process of getting my first REAL starter kit... 8" Dob, some other bits that Screw suggested I get I also have a Canon XH A1s Video camera and a Canon EOS 5D Mark 2 (I'm a photographer / filmography by hobby)

What mount are you using to hold you camera in place at the scope?

Thanks Matt - the mount I use is a Skywatcher HEQ5 Pro. It's maximum weight capacity is rated at around 13kg. The weight of the scope , camera and accessories is approx 10kg. This is really pushing it a bit for astro-imaging as any breeze, vibration etc shows up as star elongation in the exposures. The EQ6 really is the mount to go for with my setup but alas $$$ are lacking right now!
Cheers

Thanks for the reply mate, I really would love to start taking photos and I just bought a GSO 8" DOB so need to find a mount for that!

May have sorted this issue Paul - I think the focuser may have been sitting poorly on the adapter ring. I undid the 3 screws and re-sat it. I think this has fixed the tilt problem.
