Mark - i dont like the sound of the ruby red coating - you shouldnt visibly see much cheap coatings on anything for astronomical use (generally speaking) I would think? I could be wrong? restricts the amount of light that could pass thru - we actually think we have improved some old cheap second hand camera lenses light transmittence by gently accidently rubbing off what was left of the coatings just by the early cleaning style *someone* use to do LOL
I found most cheap binos to be made strictly for daylight use only -
Whats the deal with the goto? emitting frequencies that dogs dont like ??!!
how loud are we talking about? (i have nevr seen one in the flesh - other than shops)
