I have had a Celestron 90mm spotting scope in my shopping cart for some time. At $150 I cant imagine it will be that great even considering the good reviews on Optics Planet and Amazon. (My guess is that reviewers are no LR shooters) I want to get a spotter that I can DIY an iPhone mount to digiscope some vapor trails and steel hits out at 400-1200 yds. Ive also started to look at the Redfield 60mm and 80mm Rampage scopes. There is about $100 difference between the 60 and 80mm Redfields. I would be willing to spend $350 max on a spotter, but only if the $350 scope was THAT much better than the $200 models. Any advice to share?
