with a DOB on an equitorial platform do you get field rotation with time exposure. Which is most typically used on a DOB a DSL or CCD? Seems with a larger DOB you might want to use DSL with a lot of short shots.
basic question???

Ed,
I am not a Dob owner, but any equatorial mount, properly aligned, will not show field rotation.
