big binoculars v binoviewer

Postby brian mac » Fri Jun 30, 2006 11:50 pm

HI EVERYONE, JUST FOR SOMETHING TO DO ON A WARM EVENING I THOUGHT I WOULD TEST MY 25X100 STRATHSPAY BINOCULARS AGAINST MY VERY CHEAP BCF BINOMATE AT 25X ON MY TELESCOPE(EVOSTAR 120 REFRACTOR), ON THE MOON AND JUPITER, I THOUGHT THE BINO'S WOULD WIN HANDS DOWN, BECAUSE BINOVIEWERS DO LOSE A LITTLE LIGHT BUT TO MY SUPPRIZE THE BINOMATE AND SCOPE WON EASELY. SO NOW I WILL BE GOING FOR WILIAM OPTICS BINOVIEWER SET UP. THE DIFFERENCE IN SHARPNESS AND CONTRAST WAS VERY NOTICABLE. I WAS THINKING OF GETTING SOME 25-60 45DEGREE BINOCULARS BUT I NOW THINK I HAVE SAVED MYSELF A LOT OF CASH AS I CAN GET 5 DIFFERNT MAGNIFICATIONS WITH MY SET UP....[color=#66ff33][size=3]BRIAN[:D].[/size][/color]

Expected outcome. Big bins are not really suited to planetary or lunar obs. Binocular objectives are usually around f/4 to f/5 (I think the Strathspey is f/5) and the Evostar is about f/8 or a bit more? If you want a fairer comparison, pit your Evostar against a Miyauchi Saturn II (71mm f/8 binoc) [;)].

Where your big bins [i]ought[/i] to come into their own is on the faint fuzzy stuff, where the extra light will make a difference.

Fair comment stephen, i suppose it depends on what you put up against what if you get what i mean!, if you put something up against the wrong thing you will get a false result, I never thought about anything else other than the moon and jupiter, so thanks for your comments and i will try and think a bit more about the wider picture when comparing certain equipment. I do think that 2 eyes is better than 1, at least for me!..thanks again [size=3]BRIAN[/size]

I agree with all you say, especially the bit about two eyes being better than one.

Hi stephen, you told me to compare with myauchi satern 11 but have seen the satern 111 they make me want to sell all my gear and get some of those, i have been looking at strathspay 45 degree big ones they are also on cloudy nights reviews. they don't seem to want to tell you the prices of myauchi, i no they they are not cheap. if you look at the review on the strathspey let us know what you think. the satern 111 is compared to a apo refractor127 with a denc binoviewer and the results are fascinating..[size=4]BRIAN[/size]

What an excellent thread. Thanks for putting this test online. Could I ask you to carry out your test again comparing the scope and binos on faint fuzzies for me?

My large binos are better on faint fuzzy's as the scope/bino set up losses a little light and the binos have a greater field of view, but the scope setup performed well on orion nebular, 25x and 40x is fab with binoculars on fuzzy's, binoviewing on a scope is fantastic on the planets. 200x with my refractor with 2 eyes is brill.....[size=5]BRIAN[/size]
