Ethoi in the binewt
Last night Scott Tannehill & I headed to The Briars to pool our Ethoi & try them in the binewt. These eyepieces are about as wide as is feasible for binocular observing, since they are almost exactly as wide as the average adult's interpupillary spacing. They've been used successfully in binoviewers, but how would they work in the binewt?
The outcome: they worked beautifully. The view was splendidly immersive, and sharp across the field. We needed to fold the eyecups down to get our eyes close enough see the whole field, but once we did that the visual effect was remarkable. Scott remarked that the scope just seemed to get out of the way. In the binewt they produce 96x and a 1-degree true field of view, which was perfect for the deep-sky objects we observed (LMC, SMC, assorted galaxies & of course M42).
Pictures of the whole ensemble attached. And yes, the scope was somewhat top-heavy.
