I plan to buy a pair of binoculars to both aid me viewing the sky at night ( next to my 6” Newtonian ) and to use as an independent tool; I am addicted to looking at the moon, and thus the bino’s will predominantly be used for viewing the moon ( and Near Earth Objects ).
When I look at the moon with my naked eyes, the aperture is the width of my pupil. When I use the view finder of my telescope ( as a monocular ), I get a head age from the amount of light streaming into my eye ( bigger aperture and magnification ), and tent to put sun glasses on when planning a longer viewing session.
When I buy a pair of bino’s, say 7x50, which seems to be the general advise, or bigger, which requires a more steady hand, do I need to protect my eyes with a moon,- or polaroid filter ?
And if so, what is the bigger issue: the magnification factor or the aperture size ? Or the combination of both ? Are there any bino’s that can have filters screwed on them ?
Any models that are especially suited for lunar viewing ?
I am currently looking at the Celestron Skymaster DX 8x56 or the 9x63 ( both fully multi-coated ). Should I go for a pair at say 20x80 or 25x100, I would need a tripod ( or an upside down broomstick ), which would make the whole setup “cumbersome”, and I would just as well setup my telescope. “Grap & point” is key here !
On the other hand, if I can get a far more superior image with a 20x80 or 25x100, then it would be “foolish” to settle for the 8x56 or the 9x63… Although the weight of the bino’s will be a damper for long term viewing, and any hand shaking will be amplified, I like to see detail J
Any advice welcome !
