Hello btschumi, The third one is definitely Difflugia corona. The collar of the other two look more like Difflugia lithoplites. Ferry Siemensma writes in his arcella.nl : "not seldom together with Difflugia corona and Difflugia capreolata." How big were your specimen? Greetings, Hans PS Interesting,...

Hello,

Re: How much touchup is "legal"?

Hello btschumy,
there really is a lot of debris in your first image.
In your example I would prefer a cut-out enlargement of the main object and a moderate touch-up the background to emphazise the main motive.
To me your second image definitely received too much touch-up.

Re: focusable photo relay lens... anyone use these can give advice?

@bilben:
My camera on my trinocular is attached via something similar to this
http://www.ebay.com/itm/CANON-DSLR-SLR- ... 0770947923
I believe this is a combination of an adapter to the proprietary lens mount of a DSLR and a housing for an ocular. Without any optics, just tubes.

Could be a very deformed Arcella, one of the larger species (discoides, megastoma, artocrea). Only a guess.
