选项 A“Higher magnification”(更高的放大倍数)不是大孔径望远镜的主要优势;选项 B“Broader field of view”(更宽的视野)通常不是大孔径望远镜的突出特点;选项 D“More colorful images”(更鲜艳的图像)与孔径大小关系不大。而选项 C“Better resolution”(更好的分辨率)是大孔径望远镜的优势之一。
My perception of a dim image at higher power with the Q3.5 may be in part an exit pupil issue (i.e. the eyepiece focal length divided by the telescope focal ratio). For the Brandon 16mm eyepiece: 16/14.4 without the barlow used. So that is roughly speaking a 1mm exit pupil and the...

If you want to photograph planets in detail, a high magnification, large aperture telescope like a Schmidt-Cassegrain is tough to beat. These telescopes can be mounted to a tracking equatorial mount, to precisely track the movement of the planets across the sky. What is considered the best ...
How big is the Hubble Telescope's lens? What is the focal length of a Dobsonian telescope? How wide is the Hubble Space Telescope? How large are the Hubble Telescope's optics? What is the magnification of the Hubble Telescope? How far can the Hubble Telescope zoom in?
Considering the pathetic number of nights I could observe last year, one telescope was way enough for me. To me that thread makes way more sense than “what is the highest magnification you could theoretically reach with your biggest telescope?” and topics in that style (with all due...
This enables the monocular to be much shorter than a telescope and, therefore, much lighter and more portable. The downside of this smallness is that it limits the amount of magnification possible. The sweet spot for monocular magnification is 8x zoom. Any bigger than this, the monocular become...
Magnification:20X; Function:Waterproof, Fogproof, Night Vision; Usage:Gift, Bird Watching/Hunting, Toy, Travel; Structure:Refractor Telescope; Lens Type:Prime Lens; Lens:Glass; Objective Aperture:50mm; Focusing Type:Center Focusing; Aperture:50mm; ...
Many amateur astronomers get "aperture fever", an uncontrollable desire for the largest diameter telescope available. One should avoid this pitfall. I know, I have been a victim! My 12-inch SCT is an example. In my opinion, a good starting point is the 6 to 8 inch reflecting telescope or...
Or have you browsed through images taken by the Hubble Space Telescope? If you answered yes to either of these questions, you've already been exposed to the world of astrophotography. Astrophotography is simply taking a photograph of an object in space, whether it's with a point-and-shoot ...
