What are some high quality binoculars I could use for deep sky Astronomy?
I want to know what to use binocular wise in order to view deep sky objects. I want high quality color rich images. I need you to name names and be specific of what brand name of deep sky astronomy binoculars that I can use. I also want in addition to name brand specific deep sky astronomy binoculars to buy–what specifications to look for as well, because I am reading up on astronomy binocular specifications and they are really confusing to me, as I am new to deep sky astronomy binoculars–but not new at astronomy. I would prefer to have deep sky astronomy binoculars that have to go on a tripod–but that are also a rather fair price but not too cheap because you get what you pay for…
Serious replies only please!
Zeiss, Leica and Swarovski all immediately come to mind as premium bino manufacturers but you can expect to pay for them. I like the Canon IS range but they are specifically designed for hand held use (with image stabilisers) rather than mounting. The parallelogram mounts are much better than the simple tripod mounts, especially when looking near the zenith but again are more expensive.
As for bino specs, they are fairly straightforward when you know what the numbers mean. The headline specification for binos tends to be given as two figures in the form AxB where A is the magnification and B is the size of the objective lenses – this controls how much light they take in and therefore how dim an object you can see. If you are using binos hand held then generally I would advise against anything more powerful than 10x (and preferably a little less) since the image will become unusably jerky and paradoxically allow you to see less than a lower power pair. In terms of objective size, 50mm is usually about the limit that you can hand hold for long periods, especially if they are good quality. There are some cheap, lightweight mostly plastic binos out there but you want to avoid those at all costs. If you want larger than 50mm aperture or higher than 10x power you really need a bino mount, but beware – a good bino mount is comparable in price to a basic telescope and takes almost as long to set up. Ignore those brackets that fit on top a photo tripod – they are hopeless unless the object you want to view is just above the horizon.
The nearest there is to a “standard” size for astronomy is 7×50 which makes very efficient use of the available light. However the pupils of people over their mid thirties may well not expand sufficiently to use all that light so a slightly more aggressive power/aperture ratio is often recommended for older people – either a higher power pair of 10x50s or a smaller (and cheaper) pair of 7 or 8x42s. Sicne you are lookign specifically at at binos for use with a moutn you can go larger (and heavier) and higher power than is normal for hand held binos.
There are a few things to look for, but you shouldn’t really have any issues at the premium end:
Fully coated: cuts down internal reflections inside the binos that gives dimmer images. Fully multi-coated is even better. Binos simply described as “coated” are probably best avoided since it usually means only the outer surfaces are treated.
Tripod mounting bush: although I don’t like bino mounts there is no reason to get binos that don’t fit to them.
Porro prisms (where the objective lenses are wider that the eyepieces): these give better views for astronomy than the in-line roof prism binos, at least unless we are talking about very high end binos.
Lens caps and a rigid case: anything that protects your binos when not in use is a good idea.
BaK-4 optical glass (at least at the lower end of the market): this performs better than BK-7 glass used in some models. Avoid any cheap models that don’t tell you what glass they use since it may not be even that. However, going up market (in the hundreds of dollars territory) they may not say again as they begin to adopt proprietary glasses.
Finally, for low cost binos (under the $250 price point) I would strongly recommend recommend porro prisms rather than roof prisms. Low cost roof prisms tend to suffer from diffraction spikes making them less useful for astronomy. The two prisms are easy to tell apart because for porro prisms the objective lenses are more widely spaced than the eyepieces. For roof prisms they are in line with each other.
