No, not got my hands on one, Gerry. When I started to think about one, they promptly stopped making them. This is unusual as normally when I finally get around to buying new Astro kit, it’s promptly passed over by a newer and superior product 😊. Exception is Tak, of course!
Another consideration is that I usually find the biggest gains with eyepieces at the extremes of the range: high power planetary (and I still the Pentax XP3.8 was a winner and I am an idiot for moving it on) and low power wide field. I should also confess I’m no means an expert visual observer as I mainly do CCD.
But I’d love to try a Doctor 👍🏻
