Re: Thought's on ARD's
Despite what Aries said... no matter the quality of an ARD, i'm pretty certain there will be a loss of light... while not noticeable during daytime with a 56mm objective, i'm pretty sure you'd notice it on say a 42mm objective at dusk.
I'm not entirely certain about the loss of resolution... i just know the tenabraex ARDs ive used... there was an obvious and big loss of resolution and contrast.
The way glass focuses... and since the honeycomb is at the front of the lens group... it really might not cause resolution degradation if the ARD is properly designed... well perceptible resolution anyhow.
