Hi NedS,

The reason I mention in my Guide that DOBs are the least desirable type of instrument for conducting exoplanet observations is for the following reason. Exoplanet transits typically require a total continuous observing time of 4-6 hours, with ideally very minimal image movement during that time. Although computerized DOB GO-TO mounts with tracking have only recently come on the market, I am not aware that their tracking accuracy can satisfy this requirement. If you or other users have experience with such accurate tracking DOB mounts, I'd be most interested in hearing about your experience. I will be attending NEAF this year and will certainly query the DOB vendors there as to their mount's tracking accuracy.

Thanks for the question.
