Now the Council has cut off the water supply and filled in the pool, so I have been looking for another source, and a wall underneath a railway bridge looked interesting. September 2017īrown slime on rocks is one of the classic sources of live diatoms, and until recently a water feature in a local park had some interesting specimens. I also posted it on the Ferns, lichens and mosses group on Facebook, and received some nice comments. Olympus Zuiko Auto-Macro Lens 38mm f/2.8, used at f/4, magnification 5× on sensor of Canon EOS 5D Mark II, illumination from 2 desk lamps It was taken just before the deadline and I didn’t take the time to diffuse the lighting. I submitted 3 photos for a Barnard Award, and was surprised that the one of fern sori received a certificate at the Annual Exhibition of Microscopy. The workshop for Arkwright Scholars was another busy day with a dozen enthusiastic and very bright sixth-formers, and I still have to write a report on it. I must find the time to finish the presentation. Graham Matthews and I ran a workshop on image processing and I didn’t have time to finish my Powerpoint presentation so I showed some things live. I am going to be very busy with my other life ( pesticide nomenclature) for the next year or so, and I am struggling to find the time for Quekett matters. I have made a little progress on my Powerpoint on image processing. My Olympus SZ4045 stereomicroscope was the ideal tool for this job, with the 0.62× supplementary objective to give a wide enough field of view. I only used a microscope once this month, when the strap on my wife’s wristwatch came off.
