3 thumbs up on these Peter , I don't have one but an observing buddy of mine in Darwin does and I have looked thru it many times and it is in all intents and purposes perfect ! .
I could not fault it optically or mechanically , awesome at <20x and still crisp at >300x an awesome ( expensive
) top of the heap scope .
The only thing I have ever heard negative about any TV scope is the flocking material on some of the older ones comes loose over time and can only be repaired by TV , expensive exercise , but I think the newer ones don't suffer from this .? .
Yes I have put his against my 127mm Istar and yes it was better , but at $630 compared to $6000 odd , it should be .
Barry , 2 words ' Flat Field ' , these are perfect for AP as well as visual .
