The equatorial platform was essential in permitting me to perform imaging with a CCD camera, and I have used it with my 8" Newtonian as well. declination motion for a large part of the sky, especially near the meridian. (Well, all but one; the Dob is still an altazimuth scope in terms of motions, which means you can’t use the old EQ guys’ trick of locating a bright object and then using the RA or declination slow motion controls to repoint the scope to a dim object on the same RA or declination line.) I did astrophotography with roll film and a 10" f/6 reflector on a German equatorial mount back in the 1980s. Even 10 minutes of precise tracking is more than enough for anyone doing long exposure photography. with a Platform, MallinCam Theory: Basically, an EQ platform rides on a big arc at one end, and a small ark at the other, so that it rotates about an inclined axis.
