I own a pair of 7 X 35 Bushnell binoculars and am interested in getting a larger pair for astro viewing. Here on Astromart I see two i'm interested in. First a 15 X 70 Oberwerk and second a Orion 20 X 70. What is the better binoculars to go after? There both in my price range and i've no expierence with binoculars other then general observations. I do own a LX-90 and use that often but wanted to expierence the joy of "excellent" astro viewing with a "good pair of binocular's". Thanks for your help. Here I am a telescope user asking a newbie question. Appreciate you input.......... bob ellis
While I have no direct experience with these particular binoculars, bear in mind both will require sturdy mounting for effective use. It is advisable to set aside enough money from your budget to purchase a good, solid mount. You will be much more satisfied with your choice, whatever it will be, when it is mounted securely on a proper mount. I personally use a Universal Astronomics Unimount and I recommend it highly, but there are others on the market which will do the job for you, too. Best of luck with your choice.
There are 10^11 stars in the galaxy. That used to be a huge number. But it's only a hundred billion. It's less than the national deficit! We used to call them astronomical numbers. Now we should call them economical numbers. Richard Feynman US educator & physicist (1918 - 1988)
I would go with the Oberwerk 15X70. Very good optical quality and longer eye relief. Both the Orion 15X and 20X70 models have listed eye relief of only 8mm. 8mm eyerelief would be tight even if you do not wear glasses. You get a wider Field of View with the Oberwerk and the price is less too.
I don't have the two models you mentioned but I have been using a pair of 20X80mm Orion and 12X60 Oberwerk for astronomy. The Orion have better mechnical construction and incldes a heavy duty tripod adapter(~$18) but my Oberwerk has much better edge sharpness and almost no false color.
Also consider the new BurgessOptical.com 20X80 LW model if you are going to use a tripod anyway. The Burgess 20X80 LW has 3.5 deg FOV and price is the same as the Oberwerk 15X70($149). There is a very favorable review of the Burgess on excelsis.com.
Good luck and post your impressions after you get a pair.
You should take a look at the 20x80LW from Burgess optical. I have a pair and for $150, you can't beat the quality, and the company is a joy to deal with. FOV is 3.5 °, and they are the lightest 20x80s around. Since you are already getting a wide FOV with the 7x35's the 20x80 make a nice addition. My $0.02.
