I have been timing a steroid occultations for more than 10 years with IOTA.  The output seems to be similar (light curves).  I use a 25" DOB with a QHY 174M GPS camera to capture FITS files.  In Mr. Cinti's pdf "A Practical Guide to Exoplanet Observing", he states that a DOB is the least desirable mount type.  Why is that?
Doesn't the AstroImageJ aperture track the indicated stas?
