I’ve had the STS for a while and just recently traded for an ATS. It does take a few minutes to learn how to get on target with the ATS but it’s far and away more comfortable to glass with. Also when using a Phoneskope setup the angled holds the phone better and is easier to use than the STS. A used Swarovski is what I’d recommend you look for. Just make sure the seller calls in and clears the serial number and you can register it in your name.
For those of you with the 25-50W. Is it that much better than the 20-60 eye piece? I’ve never used one but have been considering it.
