Thinking about another telescope or two
Of indubitably I’m not going to stop at proper one telescope. The NexStar 5 SE I bought last clash is a fine scope, but it has its limitations. For one fetich, 125 mm isn’t a lot of aperture. It’s also restricted to a maximum 1.2-degree green of view (some astronomical targets are wider than that). And while it’s luggable at 12.5 kilograms, there are times when something even more pocket — the vaunted “irascible-look” category — would be more seductive. Especially when the NexStar’s electronics ask for additional setup time.
These desires — more portability and more cleft — can be addressed relatively inexpensively. (I said extent. Let’s not talk about astrophotography rigs for the formerly being.)
One category of telescope I’m looking at is the shallow apochromatic refractor. A short-focused-length scope with an aperture of 66 mm or so, using low-dispersion pane to minimize chromatic aberration, can give completely-field views while weighing only a a handful of of pounds. Which means I can mount one on my camera tripod; it’d also win an inexpensive telephoto lens when connected to my Nikon. I’m partiality toward William Optics’s Zenithstar 66 SD, a 66mm f/5.9 stretch that has received some pretty good reviews; it runs for about $400 with a diagonal and crate. Its focuser is the same diameter as a Schmidt-Cassegrain’s, so there would be addition compatibility. Sky-Watcher’s Equinox 66 is another choice, but it’s slightly longer, heavier, and more precious.
As for more aperture, I’m also thinking about Dobsonians again; they were my first election until I realized that the field from which we do our observing is too far away to take a Dob of reasonable aperture. They’re principled too heavy. But Sky-Watcher has a new line of Dobs coming out that might tip the scales, so to address, back in their direction. Most Dobs are either solid metal tubes or use a truss plan; the new FlexTube Dobs use a collapsible work that doesn’t come distinctly. Early reports (Cloudy Nights, Stargazers’ Lounge) suggest that these scopes stay in collimation much safer than truss Dobs, which have to be collimated every prematurely they’re put together. The FlexTubes are more portable in that they’re collapsible and therefore smaller; it will corpse to be seen whether they’re also light enough to be luggable; I haven’t seen any ballast information yet. Even a truss Dob can weigh a bit, unless you miss to shell out for one of these. I’m looking longingly at the 12-inch FlexTube, which should sell for less than $1,000 in Canada, and hoping it will be frivolous enough for us to use. We’ll see when they’re in stock.
