I'm looking to purchase a good spotting scope between $1000-$2500, in either the 45X or 60X (prefer 60X), but I need it with a long eye relief since I use glasses. Vortex has new Viper HD models for 2018, but they are not available yet. I am leaning towards that model, but checking to see what else is out there I may be overlooking. I heard the NF ts-82 is not good if you wear eyeglasses. Thanks
