Quote:I often use my SV80 ED deluxe refractor as a 'canary in the mine' to determine sky transparency and/or seeing for planets. Because of its rapid equilibration to ambient temperature its ideally suited for that. Then I decide which (if any) of the 'Big Guns' to drag out. Of course, on many nights, that little refractor does so well, I don't bother with the bigger scopes. Other ideas?

I would like to have a TV-76, essentially the same scope as the Pronto but it's a true apo with a somewhat larger aperture. It would be hard to justify when I have a very good 80mm William Optics Megrez II FD. I often use the 80mm FD on a Bogen 3040/3047 mounted sidesaddle, good for astro, good for terrestrial.Jon

Of course, on many nights, that little refractor does so well, I don't bother with the bigger scopes. Other ideas? I have a few "grab and go" refractors but the ones I use the most are William Optics 80mm Megrez II FD and a TeleVue NP-101. From my backyard, I use them as general purpose scopes, enjoying seeing what I can see, some double stars, a planet or two, various deep space objects.. They also double for bird watching. From a dark sky location, I use them as companions to my larger Newtonians, mostly using them at relatively low magnifications and enjoying the widefield, richest field views they can provide. Sometimes I test my skills by hunting down fainter galaxies and the like that are easy a 12.5 inch or larger scope but are a real challenge in a 3 or 4 inch.As far as using them to determine the seeing, I think this is counter-productive. If one is going to be using a larger scope that needs real time to cool down to perform it's best, (true of both Maks, SCTs and Newtonians), it is best to get it out there and cooling down before sunset.Jon

Quote:I don't. Have come to the conclusion- If you don't have 8", you are wasteing your time. This f/5 is easy to rollout, remove caps, and in 15-20 minutes the mirrors have reached thermal equilibrium, and you are ready to go! More light grasp and resolution than a 4" refractor at any price.
