This is the Mullard Radio Astronomy Observatory, this was captured at sunset and then photmatrix was used to bring out the details of the highlights and then pushed through a b\w filter to get the b\w effect. This is my first try at a b/w picture.
I also took a color version of this which can be viewed HERE

For my first stacked star trail I headed to the Mullard Radio Astronomy Observatory outside Cambridge to capture this fantastic One Mile Telescope with the backdrop of the moving stars.
200 x 30 second exposures at f.4, ISO 400 on my Canon 70d with the 18-55mm lens. Shot in RAW and stacked with StarStaX.
Based on US AN/ARC-52 aircraft communication radio. The valves shown are, L-R, pentode 5654, then two 6J4 triodes. right hand one is a Mullard equivalent M8248 to a 6J4. Incredibly there are also two subminature leaded-wire valves in the enclosure behind: 6021 double triode, and pentode 5840.
Circuit seen on the website of Koos Bouwknegt: www.vintageavionics.nl/index_bestanden/PTR175_.htm Also the valve museum : www.r-type.org/search.php
The circuit uses 15 crystals to provide a selectable set of stable fundimental frequencies, then harmonic products of these as well, providing more outputs still on select. I suspect but yet to understand if this is for a Wadley Loop anti-frequency-drift system.
Last night's epic visit to shoot The One Mile Telescope near Cambridge. The clouds weren't on the agenda but I made the most of what I could get. I spent more time shooting timelapse than I did still images.
The One-Mile Telescope at the Mullard Radio Astronomy Observatory (MRAO), Cambridge, UK is an array of radio telescopes (two fixed and one moveable).
This is 38 minutes' worth of 30 second exposures. I binned quite a few frames due to the cloudy sky.

This is single antenna of the One-Mile Telescope at Mullard Radio Astronomy Observatory (MRAO), Cambridgeshire. I’ve taken this back in December of 2014 onto our last trip prior Christmas. After that I’ve spent here few more nights but it’s been a while since my last visit and I hope to pay a visit later this year.
I haven’t done much of PP work on this and I even didn’t remove airplane trails because it doesn’t really bother me here. Also in the last 48hrs I’ve had only couple of hours nap due to night out shooting but this will be a story for some other time.
Technically: 134x30s taken with Canon EOS 5DmII and EF 17-40 f/4 L at 17mm, ISO 1600 wide open with CWB.

A scene I stumbled across whilst shooting. This is one of the radio telescopes at the Mullard Radio Astronomy Observatory outside Cambridge.

Looking up to the bleak sky through a long disused telescope. Maybe there's life out there? Or maybe there's snow! :P
for Macro Mondays Back in the Day. My father-in-law was an electrical engineer and we have the rustiest old "chest" with many of the above (plus Mullard etc) valves belonging to him. They intrigue me - the fine wires, components, shapes inside the still sparkling (when polished!) glass tubes. HMM EVERYONE

Closing up with the Skyvan over the Mullard Radio Astronomy Observatory, just to the South West of Cambridge.
In the back room of "Black Mouse House" a suitcase full of old valves, vintage radios and amongst the various bits and bobs something a little blue...
