Quote:In fact, there's hardly any space to fit in OAG after the full imaging train is in place. We tried to use the TS OAG with it, and there was simply no place (which I could find) to fit in the guide camera (though the OAG took excatly the optimal space).

Quote:Just saw your setup, was RH200 in focus on those pictures?I'll upload my setup tomorrow to compare...Btw, your guiding was indeed perfect, and ability to maintain focus with large temperature drop is fantastic! How precise is manual focusing (without motor) with bahtinov mask? Is there difference to motor focusing?

Quote:Hi John, Harel and All,I'm Massimo Riccardi.It's a real pleasure to see on the net a lot of beautiful images taken with my Veloce RH200.My compliments for your works.I spent several years of my life for developing the Riccardi-Honders scheme so I'm very gratified to see fine images and satisfied users.I just finished to design another Riccardi-Honders system slightly different from the Veloce RH200.It is a 250 mm diameter with a longer focal lenght ,1400mmoperating at f/5.6 and with long backfocus (about 280 mm).The performances are very high: diffraction limited from the center to the edge of a 60 mm diameter flat field.So ,for those interested to longer focal lenght and high.performances , this new Officina Stellare "baby" will be available soon.Regards.Massimo Riccardi
