It's attached with a 46 mm to RMS thread (0.800"-36, so named because Royal Microscopical Society boffins made it a microscope objective standard in 1858) step down ring from Joy's Optics. Most objectives use RMS so stepping rings are easy to source, though 46 mm anything tends to be trickier than 52+ mm.How is it attached?
I've not heard of anyone faking microscope objectives, though presumably it's been done. If my copy's a fake whoever did it also copied its near apochromaticity and ability to resolve submicron structures, so I think I don't care.Is it real?
Thank you, great work !
Not sure these are moss colonies either. Would need more pixels to tell if they're something else or just really pushing setae.Irish tribbles, fresh off our roof.
You are correct, the growth is on a rose hip.Hi Harvey, are you sure that's moss rather than a moss gall from Diplolepis rosae or a similar wasp? Looking at full resolution on flickr I'm not seeing structures which look like the desiccated, spirally arranged leaves which would be expected of a moss colony. (Also, the mosses I know all dessicate to yellow-green, dark brown, or black rather than light brown.)
For comparison, here's a quick (handheld, not focus stacked, and low-ish magnification) snap of a couple of the branch colonies across the street from work.

Dew or captured fog. Hard to tell at that colony's particular location, though from the perspective of maintaining exohydry it's kind of an ambiguous distinction.Are those dew drops on the filaments?
For those disinclined to watch videos this is a self-promotional link to a Panasonic G9 autofocus evaluation relevant to Ralf's animal detect thread but unrelated to this thread. The halophytic mosses Bryum capilare and Didymodon rigidulus might be present adjacent to Moss Landing in Elkhorn Slough but are not shown in the video and are absent from the local species list (Elkhorn is usually described as an estuary rather than a swamp, consistent with its limited number of trees, and Moss Landing gets its name from a wealthy man rather than a botanical source).
Thanks for that info. I did some online prep before going out. And the info you have is a great addition.For those disinclined to watch videos this is a self-promotional link to a Panasonic G9 autofocus evaluation relevant to Ralf's animal detect thread but unrelated to this thread.

I suppose it's time for me to note this thread's posting recommendations again.
