Re: where I can get both end caps and plugs for 2" diagonals

Plugs are sold by Astroboot, they were made by Astro Engineering. Just checked Feb 6 and I cannot see any 2" plugs, they have 1.25" plugs but they are of little use. http://www.astroboot.co.uk/AstroBoot 1.25" plugs if the link works: http://www.astroboot.co.uk/images/astroboot/dynamic/800w-532h/1396...

Re: where I can get both end caps and plugs for 2" diagonals

Best plugs I have found are from Astroboot. Anodised aluminium were made by Astro Engineering. Generally referred to on Astroboot as "Posh Plugs". Not always available, sometimes not easy to simply locate on the site, but they are good and also look good. Cannot help on the end caps. The 1.25" plugs...

Re: Did meteorites spark life on Earth?

It seems that although the earth appears well suited to life and there is a fair bit of it running aound the surface, the oceans, the atmosphere and just about every nook and cranny possible that somehow it just couldn't have actually originated here. So far Mars, meteors, passing aliens, dust and j...

Re: MARKED lack of any information for people in Wales regar

Likely to depend where in Wales you are, I didn't see a location, equally I didn't search very deeply either. I think one of the universities around Cardiff or Newport holds sessions with a local club. Otherwise this is likely the most direct source for clubs: http://www.astronomyclubs.co.uk/Clubs/C...

Re: Dark matter and dark energy: do they exist?

Dark Energy I am unsure of, I can think of one option to give the increased red shift of early/distant objects. Which is what they use as evidence for DE. Usually "nature" is simple but dark energy is sort of against that principle. Dark matter, there the gravitational evidence of it, or of somethin...

Re: GreeWitch

Yes it seems Neil has decided to call it a day. I was a bit surprised, in one of the bits referring to it, to read that Lee appears to have closed down the Leeds shop they had, would have half expected that to have kept going. However I did aleays notice that the GW wedsite referred mainly to the Ca...

Re: Red sky at night ..

According to the science behind the folklore: "high pressure traps dust and dirt in the atmosphere, which scatters blue light, leaving the red remaining- hence the reddish appearance of the sky," research by meteorologists has revealed. I always thought that the reason was bit simpler, although the...

Re: Skywatching Live Australia

Found it to be fairly poor. Very little on the actual sky and star gazing aspect. Did see some scuba diving on one of the programs? :roll: :roll: Whatever they used as cameras seem to give a washout view. Might be a better option if they returned to basics and went "star gazing". The past 2 or 3 yea...

Re: LUX and the search for dark matter

Would not be too surprised if talk of "dark matter" starts to be played down a little. Been at several talks and the early ones were all about how definite dark matter was. At one where the presenter was saying how CERN/LHC was copying the very very early time of the big bang which they described as...

Re: The public weather-eye

So the Met Office did not actually need a new supercomputer, they needed more data for the old one in order to get better forecasts. I seem to recall them saying that now they will be able to forecast up to 5 days in advance with accuracy. I equally notice that the "accurate" forecasts are only for ...

Re: Laser-pen louts

Sorry, but why is this here? This concerns people that will go and cause a problem if at all possible and has nothing to do with astromony or the astro community. Also has anyone tried getting to within 1300 ft of an aircraft? If it is above you then the aircraft body is in the way, to shine at the ...

Read this previously, just cannot think why they are bothering.

Re: Timeless black holes?

I would say the problem is we have a habit of putting zero's and infinities into anything to do with a black hole and both those cause the mathematics we have constructed around our idea of a black hole to be undefinable. If the singularity is not actually zero size and is therefore not actually inf...
