Well, dark matter - an invention without foundation? Age of the Universe changing? Etc. Etc. We're still swimming through mud, barely seeing where we're going. But one thing I'm certain of from my own observations. The passage of time is NOT fixed! As I get older it passes quicker and quicker. Peter...

Any use of regulators, even those built in to 'power tanks' to give multiple outputs will waste energy. But another option is to use rechargeable AA batteries. 6 by 1.2 volt AA batteries of 2000 mAH or so capacity would do the job nicely. You'd need a suitable holder for them. Alternatively a 6 volt...

As far as the accuracy of the end result is concerned, there's little or no difference between a red dot finder and a laser pointer for aligning a telescope. BUT there are times when a crick in the neck is guaranteed when using a red dot finder, whereas a laser pointer (held switched on by a suitabl...

The chances of the same comet being hit by two asteroids within 115 years must be immeasurably tiny. Probably Astronomically unlikely. I'll grant you that if the comet only visits us once every 115 years. But does anyone know the period of this comet? - if it's only a few years, then that considera...

A few brief breaks in the clouds shortly after midnight on Friday 26th. in NE England. Still a lot of thin cloud, but I grabbed my binocs and enjoyed the amazing view of the round fuzzball with its bright core. Then before the clouds closed in again I mounted my Canon 350D on a tripod, roughly point...

There is now a much sturdier tripod supplied with the EQ5. See a setup on Ian King's site at http://www.iankingimaging.com/show_prod ... &offset=20
