Teesmouth Bird Club

Looking to purchase spotting scope and would like members views on good make/size and where to buy?
Have tried Zeiss 65mm and was impressed by clarity. Is there a significant difference with a 80/85 mm?
May have a go at digiscoping in the future.

1st: It has to be the Wren. A bird with attitude. Always close-by.
2nd: Kestrel. Hangs around while a sort out my camera settings
3rd: Blackbird. For me, the best song!
