I have the older Kowa 663 that I’m looking to replace. I use the fixed 30x eyepiece over the variable because the 30x is a wide angle and so much clearer. I find myself consistently wanted more zoom with clearer picture. I’d love the new fluorite Kowa, but just can’t afford it. Would like to come in at 2k or less. Any spotter be a good UPGRADE? More zoom, better glass, better variable eyepiece?
