[QUOTE="Guns & Glass, post: 16990, member: 1718"] A newbie to the 'Board', and read with interest this subject. Just wanted to throw in some info adressing situations/specs, then the Burris product. Limited adjustment range-in this case 22" on a 1" tube. That's a good thing for a designer to do. There are optical performance limitations on all optics since physics & chemistry are the same for everyone. The limited adjustments or 'stops' are purposely design/manufactured in to keep the sight picture resolution high. The more adjustments are made....the lower the quality of light transmission thru the tube especially at longer ranges. This is why it is good to use elevated bases, or rings again using the word 'designed' because it improves optical performance. Mirage is a good thing to be able to see. Reasons are: >Tells you of glass & optial quality. >Since it affects shooting, what you can't see, you don't know how or what to do about it. >Mirage of barrel??? Sun shade(s), special Mirage Tubes, barrel coverings, or just simply longer times between shots can all help. Range Mirage??? Being able to "see" where it is, can help determine when to take a shot, or even what direction to shoot in. Ie., say one's Prarie Dog hunting and at 10 O'clock (off shooters left-not time wise)there is alot of mirage due to ground rock formation. But at 2 O'clock (shooters right) there is none. Shooting to the right could be better at that time. As the sun travels, it can/will change. Turning down the magnification only hides what influences shot quality. It's better to "see" so you know what can be done. If mirage isn't present, or is minor, and a lower magnifacation is easier for you...at that time, then reduce it. Light Gathering- simply doesn't exist. It's a term that in my 'minds eye' I see little arms extending out from the objective area, scooping light photons into the lens. Would like to see more usage of, "Light approach, and Light Transmission". Burris uses a more recessed objective lens which helps to "control" light thru the approach. Almost like a mini sun shade. Light Collector is a very neat & functional patented device that acts just like an internal sunshade'. Certainly makes sight pictures sharper. The Signature, and Black Diamond models are vastly underated due to their past sales literature that was lacking in better explainations. [/QUOTE]
