These ranged from a 3 5-mm Panoptic that yielded (with the Paracorr) 62x and a field slightly more than Io across, to a 7-mm DeLite giving 308x and an 11-arcminute field.
Boosting the magnification to 308x and racking the eyepiece from one side of focus to the other revealed diffraction patterns suggesting that the optics in this scope were very good, but Vega was really too bright for a good star test, so I nudged the scope to the northeast to look at Epsilon Lyrae, the famous Double-Double.
