    I have just become the owner of an ex-demo Kowa 883 having used a Kowa 823 for the last 22 years. I really, really like it does make me realise how good the 823 was, the 883 is a little bit brighter and a smidgeon better resolution but the step up is fairly small, perhaps my 823 was a cherry...

    Which bird have you wanted to claim but couldnt

    I was at Dungeness in August a few years a go, I got onto a falcon at some distance, it was small dark and quickly moving away from me and it felt very good for Eleonora's Falcon but poor views for 30 seconds meant I didn't do anything about it. Then a couple of days later one was seen and...

    Opticron IS 50

    I have a one with a 20x eyepiece, I use a kowa tsn 823 as my main scope and whilst the opticron can't compare in terms of brightness, contrast etc. It is a useful second scope and the image is pretty good as long as light conditions aren't too challenging
