Re 120mm Esprit
Hi Tony,
I can't help you with the 120mm Esprit, but I do have the 150mm Esprit and can comment on that.
My set up is a Canon 600D with a cold finger, Skywatcher flattener and spacer that came with it. The focuser is extended to 6 on the scale when using this setup. I'm an Astrophotographer and have never had an eyepiece on it.
The field is dead flat over the whole DSLR sensor with no sign of curvature.
For me this is a lovely telescope that I use to photograph DSO's greater than 20', for DSO's less than 20', I switch to a Meade 12" F8 LX850.
My final comment is that the 150mm Esprit will be with me until they put me in a pine box, "the Meade" well ask me in six months, I have only had it for a couple of weeks and have not had a chance to take any serious shots yet, all the above run on an EQ8, which I'm very happy with.
Cheers
Peter
