Re: The Moon through binoculars

I have the Helios, Voyager, zoom 10X-25X42mm monocular. It's very good for general purpose and astronomy. It also functions as a microscope with its minimum focal distance of 25 inches. The Voyager can be attached to a grip or tripod. It's good to see insects, especially butterflies, in intricate de...

Re: The Moon through binoculars

The man who uttered that was Pascal in 1833 or thereabouts. Ironically, it was at the same time that Fraunhofer was making his first solar observations.

Re: The Moon through binoculars

When the book was published, it was a Newtonian universe, the galaxies were regarded as clouds of gas in our galaxy, and the Sun was burning like a piece of coal, not nuclear, etc. The author would have been astonished to know what astrophysics has revealed about the Universe since then.

Re: The UFO files

I've checked in Webster's Stella and they use the same "Aerial" as in the English dictionary. As you know, some Americanisms are spelt differently. Yes, I know what an Ariel is here.

Re: The UFO files

Ariel might be the American ( Webster's ) spelling. In the "Tempest", Ariel is a spirit of the air.

The UFO files

The US Congress has ordered the intelligence agencies to reveal all that they know about UFO activities. Congress's directive has given less than 180 days for the Office of Naval Intelligence the Unidentified Ariel Phenomena Task Force and the FBI to give detailed analyses of UFO data that they hold...

Re: Beast from the East.

If it's any consolation Brian, whatever Nature throws at us, she's equipped us with a brain that, given enough time and resources, can solve or, at least, moderate these problems.

Another Beast from the East?

According to the Guardian there's a high possibility of another "beast from the East" in the middle of next week, due to a threatening sudden stratospheric warming. Along with Covid-19, it would finish off more of the old folk. Heartless as she might seem to be, Nature insists on staying h...

Re: Earth to get a mini moon ..

I was forgetting about the La Grange points. There are concentrations of interplanetary dust and possibly a few old rocks of some discription at Earth's La Grange points.
Jupiter has a million Trojan asteroids at its La Grange points.

Scottish aurora

A brilliant auroral display was shown on BBC News this morning. The display was imaged in Elgin Murray. Is it a consequence of the recent solar filament ejection?

Re: Jan 8th Bright CME

I saw it this morning Jeff on space weather and wondered what the effect would have been if it was face on to the Earth. Would it be the same effect as a mass coronal ejection, knocking out power grids,etc?

Re: Nebulae in Auriga

A super image in a rich star field. We can only wonder which stars seen on the faces of the nebulae are in front and which are behind the nebulous clouds. Either way, the stars give a strong 3D effect.

Re: Observing with 66mm William Optics and 2” Eyepiece

I've found that the best finder is a laser pen attached to the 'scope ( including on my binocular mirror mount ) and used responsibly. Most pen diodes wilt in cold weather, but a heating band would solve this.

Re: Observing with 66mm William Optics and 2” Eyepiece

It's surprising how effective a small refractor can be. As you say Jeff, an EQ can be awkward, but one way to ease the problem is to mark the ground so that the tripod legs are always placed in the right position in the observing place. I use a small EQ when I observe the Sun with the 70mm modded PS...

Re: Book publishers cease publication

A great deal of modern housing doesn't have the fireplace, so there would be nowhere to have a fire indoors. Another example of over-dependancy on a single source. In this instance, electricity.
