About Coated Lense Binoculars
Binoculars consist of numerous air to glass surfaces with each individual surface contributing to the loss of light. Coated lense binoculars help prevent the loss of light with one or more of the surfaces being coated with one or more layers of anti-reflective coating. Never buy binoculars with uncoated lenses, the lack of coating means that around 50% of light could be lost making non coated lense binoculars half as bright as their coated counterparts.
Coated lense binoculars used to come with a hefty price tag but now most binoculars come with coated lenses in one form or another and top quality fully multi-coated lense binoculars are often within the price range of many users.
The greater the number of coatings and the more surfaces that are coated the less light is lost so if you are looking for the best binoculars you want fully multi-coated lenses.
There are basically four grades of coated lense binoculars although some manufacturers have developed their own, exclusive, high quality coatings which offer greater durability and further improved light transmission with other added advantages:
Coated lense binoculars means that one or more surfaces are coated with one layer of anti-reflective coating. If only one or a limited number of air to glass surfaces are coated such binoculars will provide you little more light transmission than un-coated lense binoculars.
Fully coated lense binoculars means that air to glass surfaces are coated with one layer of anti-reflective coating.
Multi coated lense binoculars means that one or more air to glass surfaces are coated with multiple layers of anti-reflective coating. Like coated lense binoculars you have to be careful here as just one surface could be coated!
Fully multi coated lense binoculars are the best that you can buy. All air to glass surfaces are coated in multiple layers of anti reflective coating.
Fully coated lense binoculars can increase light transmission from 50% to around 80 - 85% which is now the norm for low cost binoculars. If you want something a bit more special that will increase light transmission to 95% or above then you want to go for fully multi coated lense binoculars and, for extra durability and advance quality viewing, take a look at the exclusive coatings offered by some of the top manufacturers. Bushnell Elite binoculars come with Bushnell's exclusive XTR technology (60 layers of coatings on each prism) which delivers 99.73% light transmission per lense.
The difference between fully coated lense binoculars and fully multi coated might not sound that great but once you have owned binoculars with the best quality optics and coatings you'll never look back. The light transmission, resolution and clarity of top quality binoculars is amazing and the enhanced viewing generally makes the higher price tag well worth it.
A few fully multi coated lense binoculars are Bushnell Elite, Bushnell Legend Binoculars, Bushnell Natureview, Pentax DCF SP / XP and HR II, Pentax PCF Binoculars, Nikon HG L DCF Binoculars and Olympus EXPS I Series Binoculars.

Suerte.
That is very normal for anti-reflective coating. The only other color I have seen is a slight blue tint. The quality of the coating doesn't play into the color of the tint. People will notice, but not as much as they would notice their own reflections if you had skipped the coating.
While the Lexus LFA may carry a hefty price tag of $375,000, it hasn’t stopped Toyota from selling out its new luxury supercar in Japan. According to reports from Japanese media, the entire allocation of 165 units have been sold out two months ahead of schedule. Reports say that the application schedule to purchase an LFA [...]

If your choice is really limited to these two options, then I would favor the reflector. Why? Aperture I guess. But seriously, you should take the time to get a scope that you really want for reasons that you understand. You are at the low end of the price range for a telescope, and the options there are very limited. Can you afford/ get delivery on the Orion StarBlast shown below?
If so, it's a better scope for your money than either of the ones you mentioned. If you can extend a little further, I would look into a Dobsonian. You can find decent scopes at oriontelescopes.com, meade.com, and celestron.com, but you usually get what you pay for.
The advice about visiting a local astronomy club observing session is right on. You will get a chance to see through several scopes without having to buy them first, and you will receive a warm welcome and plenty of good info. They can be found on line. Take your time. Don't buy a scope until you know why you want the one you're buying.
I’m dying to get it. THIS IS A SEXY MONSTER OF A LAPTOP!! I’m getting it refurbished from TigerDirect though so it’s about $1000 less, plus about $300 for the warranty. I can’t wait I’m saving up!!
No, they fall out naturally, in the same way as your eyelashes cycle normally. Don’t worry!
