Hi Martin,
I have been looking to move forward into a dedicated OSC and decided the O71 was the go for me and my set up.
I currently use the modded canon 40d that I bought from the classifieds.
My scopes are the Orion EON 115, f/l 805 mm f7.
And the explore scientific ed80 480mm f6
With this I think will get 1.22 arc sec/pixel for the Orion and 2.05 with the Es ed80
I have been reading this:

I have been aiming to stay in this 1-2 arc sec per pixel as I have little experience in any of this.
I see that your arc seconds per pixel are much lower and wonder whether I was over thinking it.
Have you taken the arc seconds per pixel into your decision and purposely aimed at close to and below the 1?
I too will be interested in the discussion
Jack
