I am looking for a lightweight compact scope to use from inside my house I have been looking at quite a few and the lightest one I've found that comes inside my budget of £500 is the Kowa TSN 501/502 it says it weighs 415 grams. I have never used any Kowa products. My "outside" scope is an old Spacemaster from the 1990s which was fine till I developed arthritis in my thumbs, now its awkward to handle. I've had several different scopes over the past ten years but that was before the arthritis. I own a pair of Opticron Discovery 8 x 42 which after five mins I find heavy but obviously can put them down after couple of mins. I want to be able to see the wee birds end of garden more easily so thought a compact scope might be the answer, maybe it isn't am sure if anyone reads my thread they will say. I have looked at Opticron, Hawke, Vortex etc but they seem heavier than the Kowa. I do have a Velbon Ultra Luxi SF tripod but would prefer to hold the scope in my hand, maybe I'm expecting too much at my age and poor health. Any advice will be very welcome, thanks.
