This will be my first post here on CN.
A fellow whose pictures(when he posts) and 'scopes always impress me enormously is Harald Paleske.It's a surprise to me that nobody else has brought him to attention.
His site is:

It's in German.The pictures tell their own tale,but if you ache for a translation,Google 'languages' or somesuch will cough up an approximation.
