A Full Moon…

Away in Wales at the moment and regretting not bringing a scope (this wold have been so much better); but here’s a picture of tonight’s full moon taken through a 300mm zoom lens. A bit of a crop, but no other editing- the reddish colour is a reflection of the sunset.

Looks good through the 12×70 binoculars as well!

Polarising objectives for LOMO Polam P-113

Another ebay bargain – 7 pristine polarising LOMO objectives – scary ordering these as posted from Russia and I wondered if they would turn up…..

But when they did, each lens was carefully wrapped in a small piece of bubble wrap and the whole box carefully packed in another box – subtlety unlike the Americans who I have found wrap everything in a solar system’s worth of bubble wrap!!!!

Bright field vs. crossed polarisation views of microscope slide of material from LRO pot pond 28/5/2018

I used the centrifuge to concentrate down material from “open water” in the pot pond (i.e. not near edge or bottom or plants) and views the result in the LOMO Polam P-113 microscope, by bright field & crossed polarisation.

Note that such open water samples do not contain diatoms – which are famously birefringent.
