Did you know?
WitrynaFor starters, Dobsonian telescopes usually have a shorter focal length than Schmidt-Cassegrain telescopes. This means that Dobsonian telescopes have a wider field of view than Schmidt-Cassegrains, but as a result, their magnification isn’t as strong. Dobsonians, despite being physically larger, are both lighter and less expensive than … WitrynaFor me, a 100% visual astronomer with a refractor, SCT and Newtonian scope, the views aren't that different when you account for differences in field of view and aperture. The ergonomic issues mentioned are right on though. The quality of the scope optics is also a big factor, especially for planetary. ...
Witryna15 gru 2024 · In any case the popular Newtonians today are fast designs, typically f/4.5 and even faster, and parabolizing a mirror like that requires some talent to pull of in large numbers, even if it is largely computerized. 7.

For the new scope (or scopes), I'm thinking about a RASA 8 and a Ritchey Chretien 10". Another approach I've considered is a Celestron Edge HD 11 + Hyperstar to reach both ends of the spectrum with a single scope. The cost of the RASA + RC …
WitrynaThese issues are mostly fixed through the use of a corrector lens, which also appears to fix the newtonian reflector issue too, being diffraction on the brighter objects in space. ...

A 4" short focus ED / APO frac is a superb instrument for low power wide field deep sky work (on a portable altaz mount) or for small scale deep sky imaging (on a good equatorial) - but the 6" Newtonian is much better as a first/only ...
Witryna30 wrz 2015 · For example, an 8-inch f/10 SCT (7.6 inch unobstructed aperture, 193 mm) collects (193/81)^2 = 5.6 times more light from the subject. For example, if the 81 mm …
Witryna26 paź 2024 · The SCT will always have the edge due to the aperture but for sharpness and nice wide field views the refractor is lovely. If I was on a fixed budget and had to decide between SCT, refractor and a reflector this would be a tougher choice.
