I've always liked small refractors, and have always been on the lookout for the perfect small scope that would do double duty as a spotter and an astronomical scope, within the obvious limitations of small aperture. I've tried a 70ED scope and more recently a Megrez 72 but felt they were a bit heavier than I'd like.
The old William Optics ZS66 is lighter but is essentially restricted to 1.25" eyepieces due to focus issues with larger ones, so that limits the field of view to around 4 degrees, which is a bit restrictive for terrestrial since the Megrez 72 with its 2" focuser can achieve 7 degrees, similar to binoculars.
Have thought about a dedicated spotter but their prisms are either fixed straight through or 45-degree, neither ideal for astro.
Anyone else using a small scope for both purposes? What are you using?
Cheers
