OFFICINA STELLARE VELOCE RH250-AT f/5.6 LRGB The special internal corrector isThe Veloce RH250 AT is unique in the Veloce lineup. Originally designed for a scientific project, the RH250's performance was so good that Officina Stellare decided to put it into full production. Unlike the other Veloce telescopes which are f 3, the RH250 is f 5. 6. While it is a little slower, the RMS spot size at the edge of the field (not just on axis) is an astounding 3. 6 microns, making this one of the sharpest compact imaging scopes available.
