when we shoot at 1k we use a leica 77 20-60 and a zies 85 20-60 both scopes are capable of seeing 6mm holes at 1k if and i say it again if the conditions are good and they are in the white or blue never seen any holes in black we have days you cant see holes at 600. neither scope is current model leica is before apo lens and ziess before tfl. dont know if the new hd type lenses will help or not but they cant hurt anything but your pocketbook i think the ziess is better than my leica maybe the 85 mm objective or just better lenses i know that having verry good eye sight helps my freind can see holes with either scope way better than i can. hope this helps a little good luck
The new Leica 82mm Televid is fantastic! Even the "bird people" rave about it on their forums... Another plus is a digital camera can be easily adapted and the images are super! I saw this set up at the WSF show in Reno. Really slick... just a bit pricy.
I have a 8" Celestron that I can clearly see the rings around Saturn with. I also have a Kowa that I have a 27x and a 60x(?) lens. The zoom lens have to much glass in them. You are much better off with a single power lens. They are much clearer & sharper than the zooms. The 27x lens is about as powerful as you want so you can see the mirage and not hinder your vision.
