Re: Advise between 2 scopes for astrophotagraphy
The difference between an astrograph and a regular newt is the placement and quality of the focuser. An astrograph has its focuser placed a little closer to the primary mirror to eliminate the back focus problem and as mentioned earlier, the focuser will be of better quality probably with a 10:1 fine focus knob.
