We played through the final 3 games of a CoraQuest campaign today. It was fun ! A nice progression of power - in the end we just smashed through the simple mobs and the bosses. Maybe we have do dial up the difficulty the next time.

With the rail done my #optics #microscopy project is going into the next phase meaning new problems.
I want to use a beam splitter to direct some light to a guide camera (small Basler Cam on the side). However astigmatism from the 50/50 mirror is so bad that I don't get a usable image.
Help?!

My first try at large format printing from macro photography.
Turned out nice, now I need to find a good place for it.

My project comes together, slowly. The #WeMacro focus stacking rail can be controlled by #micro-manager with an adapted mm custom Arduino.
Next step will be triggering the Sony alpha camera - likely via a TTL pin and not directly from software.

It's nice to receive stuff from Thorlabs. Even if it's just some thread adapters. Thank you!

I just found Jay's adapt-o-matic for custom 3D printable thread adapters.
It works surprisingly well and treads engage on the first try.
I am not ready to trust them on load bearing connections but for the m42-sm1 to connect a camera it's a time (and money) saver.

Der eigentliche Skandal ist ja, dass in einem Naturschutzgebiet überhaupt Torf abgebaut werden darf. Ganz legal, mit dem Segen des grünen Umweltministers. #MoorMussNass

800 Lkw-Ladungen Torf fehlen: Niedersachsen verklagt Konzern auf 4,5 Millionen Euro
Das Land Niedersachsen klagt gegen ein emsländisches Unternehmen und fordert Schadenersatz in Höhe von 4,5 Millionen Euro. Es wirft dem Großkonzern unter anderem vor, zu viel Torf abgebaut zu haben.

How to get into nature.
A question for microsky.
I want to build a custom horizontal setup and am thinking of mounting a prior xy stage vertically.
Is this an obviously dumb move and it will break?

This it what it looks in practice. It is boring and I should go to bed but I am still missing 2 positions so I post here #macrophotography #lichen

Up and down we go.
It would be nice to automate this - I have not yet found a good way to synchronize a prior stage and the wemacro rail.
Its semi-manual at the moment.

Stack and stitch works surprisingly well on macro...

Stacking with raw and 4-pixel shift. The images blow my mind - the process, shooting, stacking and developing from raw, is slow - - Probably not what I will be doing regularly.
Lichen people: Do you have ideas how to use such images to add value?

Tetracladium setigerum #AquaticHyphomycetes in a foam sample from Hannover.
The melting snow filled a drainage ditch which runs to the Mittellandkanal with a small waterfall. Lots of foam for a nice sample.

Yesterday was my first experience with AI slop contaminating my search to the extent that I was not able to resolve my question (in the time I had).
I was looking for a naan bread recipe and found only incoherent, implausible or recipes lacking a ingredient list - but with many "beautiful" words.

I haven't been #lichen posting for a while and now I am back with a question (I should not touch sterile crusts…)
This one is from silicous boulders in a small forest creek 480m asl.
Grey areolare crust with prominent green deliminated soralia. K-, C-, KC-, P-. UV white-ish.
