I am looking for the best spotting scope for about $1000.00. Don't mind going over a little if it is worth it. I will mainly be glassing bean fields late in the day/dusk, from my truck. I want straight if I can get it. I want to be able to tell antler size at, the most, 500 yds. I have looked at Kowa, Pentex, Nikon, Vortex. Not sure which will give me the best view for the money. Thanks for any help.
