The moon is a clipped planchet
....never mind a harsh mistress...
**Yawn** Its 5:40am local (Sydney) and the moon is eclipsing. She looks just like a mint error, settling into the misty haze over Sydney this morning. Here's a shot taken about 25 minutes ago: http://mendosus.com/jpg/eclipse-5-5-04.jpg Pretty average quality photo, but she's sinking fast into the murk. Whaddy'a reckon? AU58? -- Jeff R. |

An update, FWIW:
http://mendosus.com/eclipse.html The moon's about to set - the sun's about to rise, so this is the best I can do. Lousy photos, but nice toning - and the moon is just about to be dipped (not in thiourea - in the horizon) -- Jeff R. |

I was advised that the moon would appear to have a crimson / orange colour to it due to `earthlight'....but sadly, it was all just a bit grey. Then again, maybe the thick cloud cover here had something to do with that.....never saw the firkin moon at all all evening. :-) Ian |

I did much better 4 years ago: http://faxmentis.org/html/science12.html and again 3 years ago: http://faxmentis.org/html/science30a.html but I didn't bother setting up the 'scope or getting out the proper cameras this time, 'cause it was so low in the sky. -- Jeff R. |

The umbral shadow has now gone at 11.25, but definitely traces of the penumbra are visible in a distinct dulling at the top. [back on topic] Why are UK clipped planchets so rare?

Nah, I would say just VF, look how grainy and worn the edges appear, yep, definitely only VF. Winde |

Nice photography there matey! and again 3 years ago: http://faxmentis.org/html/science30a.html nice again but where's the toning? It's looking like it's been dipped....or (gasp)..dremmeled! :-) but I didn't bother setting up the 'scope or getting out the proper cameras this time, 'cause it was so low in the sky. why is that? atmospherics / light polution / too short a cycle to bother with / other?

It's looking like it's been dipped....or (gasp)..dremmeled! :-) Coupl'a factors at work here. The first set (science12) was taken with a webcam mounted on a 200mm f.l. lens. At low light the webcam got a bit noisy. This was a total eclipse, and it did (as you can see!) exhibit substantial reddening (izzat a word?) The second set (science30a) was taken with a 35mm camera at the prime focus of a 1000mm f.l. telescope (f/8.3), using Elite Chrome transparency film. (Not afocal - no eyepiece used). This film is well known to be excellent at reproducing accurate colours at low light. Those "dipped" colours are pretty accurate - note that the one at maximum eclipse shows a faint tinge of red at the darkest bit. I was exposing the frame for the body of the moon - which washed out the reddish dark bit. No whizzing required. but I didn't bother setting up the 'scope or getting out the proper cameras this time, 'cause it was so low in the sky. why is that? atmospherics / light polution / too short a cycle to bother with / other? The first two certainly. Dirty atmosphere close to the horizon. I live in the suburbs, and the sky is pretty bright. Yuk. Pragmatically: *None* of my 35mm cameras are currently operational! Its so long since I've used them (I've gone digital) that they all have flat batteries! The mechanical ones (no batteries req'd) I couldn't use 'cause I don't have the lenses handy anymore. I couldn't use the webcam, 'cause the laptop has been pinched. :-( Plus - I just couldn't be bothered dragging the big heavy telescope 10km to work, where I could have found a clear horizon to the west. Not at 5 in the a.m. (yawwwnn) So - I just pointed the Mavica (at full telephoto) at the moon and hoped for the best. Very average results, but heck - it proved that I saw it, and I *have* already captured a total lunar eclipse nicely. Plus - I'm getting old and losing enthusiasm.... Other interests, too. I wonder how many folks saw the half-eclipsed moon and thought: "hmmmm. Clipped planchet." Did I mention? I'm going senile, too. Now, what was the question again? -- Jeff R. (I think) |

The umbral shadow has now gone at 11.25, but definitely traces of the penumbra are visible in a distinct dulling at the top. I couldn't discern the penumbral shadow at all, due to a combination of sleepy eyes (stumbling out of bed at 4am) and a light hazy cloud cover. I have to say, though, that the sight of the fully eclipsed moon - glowing crimson and so dark that it doesn't wash out the stars - is nothing short of magnificent (and *spooky*!) [back on topic] Why are UK clipped planchets so rare? Good quality control at the Royal Mint, no doubt. Same here in Aussie. Mind you, I suspect that the astronomical (back off-topic!) mintage figures in the US could have something to do with this, too. -- Jeff R. -- Tony Clayton or Coins of the UK : http://www.tclayton.demon.co.uk/coins.html Values of Coins of the UK : http://www.tclayton.demon.co.uk/values/coins.html Metals used in Coins : http://www.tclayton.demon.co.uk/metal.html Sent using RISC OS on an Acorn Strong Arm RiscPC ...
