Off topic - but worth a mention - a bino new on the market that is receiving some favourable reviews from owners of other  unquestionably very good quality binoculars is the Orion Expanse 7 x 35 which offers an incredible 14 degree TFOV !  

Regards to all --Kenny.


Subject: Rugged Exposure 10x42 @___rom Big 5

From: rab <rab5@___ring.com>

  I took this blue rubber armored, waterproof (so they say on the box) roof  prism binocular to Gates Pass Lookout this evening between 6:30 and 7:15 PM.

  Star testing these on Vega and other objects, I continue my praise for these cheap binoculars that I purchased the other day, on sale, from Big 5 Sporting Goods. Daylight images are excellent, but night-time and star testing tells more.

  Image quality, ghost rejection, and parasite rejection are on a par with Nikon Venturers, however these do not have phase correcting coatings on the roofs. Transmission seems on the low side (the coatings are MgF), although the image doesn't appear to be unduly yellow, which would caused additional light loss (even the Nikons never appeared perfectly 'white' to me).

  Eyerelief is a bit shorter than the Nikons, but adequate for some eyeglass wearers, and I can see most of the field with my regular spectacles, and all of it with my special, miniature, compact spectacles. Fit and finish not up to Nikon standards, hard to tell how robust they are without dropping them, but these are remarkably good glasses and for peanuts.

  Regards, Dick.



Binocular List #277: 24 November 2003


From: " Jack Kelly" <jkelly@___mentsales.com>

  Regarding John Anderson's Dekaris serial number, I have some Zeiss production records which indicate that they manufactured 2 examples of the Dekaris in the year ending September 1928, and 867 in the year ending September 1929.  These same records indicate that the last serial number through September 1928 was 1442819.  This would lead me to believe that John might be the owner of one of the very first production models of the Dekaris.

  On a different note, I just found an old book, "The Telescope" by Louis Bell, PhD, first edition dated 1922.  You are most likely familiar with it but it does have some interesting information on binoculars and a nice photo of a Clark 4" binocular telescope.

Regards,  Jack
