Subject: Moon phases and a thin crescent
|
Since the middle of July I found myself trying to capture more and more waning Moon phases from the last quarter Moon on the 17th. I've done this before (actually a much longer sequence which can be seen at http://www.digitalsky.org.uk/moonview5.html ). I do have a capture for the 18th but seeing was poor and the result rather messes up the sequence - I might have another go at it later. Anyway here's the full sequence capture up to a very difficult thin crescent on the 23rd July which was hampered with criss-crossing clouds. http://www.digitalsky.org.uk/l2006/lunarphases_july_2006-fullsize.jpg Now, I thought the 23rd would be the end of the story, however... This morning (24th) I got up early and took a look into the north-east. I was somewhat surprised to see lots of clouds around. I decided to hang on and keep an eye on what was happening. I knew the Moon was in there somewhere but I couldn't see any stars to find my way around. I saw Venus and decided to set up my telescope in my front garden, just in case. At 04h00m UT I was tired and on the verge of giving up. I still couldn't see stars but could see things around me in the garden very clearly as the dawn was advancing fast. Suddenly, between two thick cloud banks, I picked up a thin white line in my binoculars and sprang into action... A few tense moments when I had to move the telescope to avoid a lamp post and a few snips at a straggly bush in the front garden (which now has a rectangular section taken out of it!) and I had the incredibly faint crescent in my finder. Moments later, there it was on my computer screen - a sight as beautiful as any I've ever seen in the sky. Small distant birds were flying across the giant crescent - an awesome sight. Here's the end result... http://www.digitalsky.org.uk/l2006/2006-07-24_04-13-14_flat.jpg -- Pete http://www.digitalsky.org.uk

Your particular nasty habit of mixing moon phases with planetary phases is sub-geocentric and ultimately destructive. Changes in orbital orientation between planets in common heliocentric motion shout out that changing phases indicate heliocentric motion,dwelling on phases with a Ra/Dec system is lethal to the information carried by changes in orbital orientation and recognition of the Earth's orbital orientation changes in accordance with Keplerian geometry and motion - "When you speak of the components of motions, you speak of something which is only imagination, and which does not exist in reality; for nothing performs the circuits in the sky except the body ofthe planet itself [Nihil enim in coelo circuit praeter ipsum corpusplanetae]; [there is] no orb [nullus orbis], no epicycle [nullus epicyclus];you, who have been initiated into Tychonian astronomy should know that. Now, if we adhere to the fundamental claim that noth-ing moves except the body of the planet, the question then arises:what is the path traced out by the circumvolution of this body[linea corpor=E8 circumeunte" KEPLER The Newtonian mutations of Copernican heliocentricity are far worse than the Tychonic mutations,it gives rise to people who are unapologetic about their sub-geocentric celestial sphere.concepts.Unable to use orbital orientations,celestial phases join the horror show which passes itself off as astronomy.
