TV-60 not too badly priced at BINTEL. Suberb 'scope capable of 180x with 2-4 Nagler Zoom and 4.3deg with 24mm Panoptic. All you need is a quality 1.25" diagonal (60deg Everbrite would be nice but check with Tele Vue that it does not take up too much travel). The 'scope is very small 254mm long (OTA). Note there is also a TV-60is but is double the price and aimed for imaging.
