Taken at sunset yesterday with the phone.

Just thought I'd share... cool


120mm Refractor f/5 .

Specially Modified pier mounting ( One of a kind ) made by a very good friend and his crew for this scope.

I built the tripod...I'm STILL not done, Lol.

Cliff,

Just wondering.

Gravity is supposed to be a pretty weak force.

The galaxy M31 is blue shifted and this implies it is coming towards us. One source I read estimates it's approach speed to be 30,000 Kilometer per second.

Now, if all the galaxies are receding from us at an increasing rate, does this imply that Dark Energy is weaker than gravity ?

Just wondering.

p.s. Nice telescope; Shame about the tripod. grin

I broke the other tripod filming one of the PANSTARRS comets, lol. Two of the legs broke back to back one cold winter evening a few years ago...It bloodied me up fairly good...
So I modified a stronger one. wink

M31 is part of a local cluster of galaxies nearby, some suggesting the possibility we have already begun colliding. Because of it's location close to us, it is blueshifting. If it were further out, it most likely wouldn't be appearing blue spectrally.

I enjoy observing faint wisps of dust lanes in M31 wth the scope, along with m32 and 101 galaxies (part of the same local cluster along with our milky way)in the same field of view (fov).

Notice Hal that Cliff avoided your question about dark energy and dark matter. He doesn't have a clue, Lol. rolleyes

A large coronal hole is turning towards Earth. Solar wind from the structure should reach Earth Sept. 28th, 29.

DIMINISHING SOLAR ACTIVITY MAY BRING ICE AGE BY 2030

Quote from article

“There is no strong evidence, that global warming is caused by human activity. The study of deuterium in the Antarctic showed that there were five global warmings and four Ice Ages for the past 400 thousand years. People first appeared on the Earth about 60 thousand years ago. However, even if human activities influence the climate, we can say, that the Sun with the new minimum gives humanity more time or a second chance to reduce their industrial emissions and to prepare, when the Sun will return to normal activity”, Dr Helen Popova summarised.

I don't know what is going on, but October has been running 10 to 15 degrees above normal for Tennessee.

The summer in general has been hot with 90 days above 90 degrees thru the summer.

They do not predict La Nina or El Nino for the winter, but La Nada meaning the winter is neither here nor there, but a true mystery.

Little Gem Nebula shows off its jewel tones

07/11/2016

Copyright ESA/Hubble & NASA; acknowledgement: J. Schmidt (geckzilla.com)
Description

The NASA/ESA Hubble Space Telescope had imaged NGC 6818 before, but it took another look at this planetary nebula, with a new mix of colour filters, to display it in all its beauty. By showing off its stunning turquoise and rose quartz tones in this image, NGC 6818 lives up to its popular name: Little Gem Nebula.

This cloud of gas formed some 3500 years ago when a star like the Sun reached the end of its life and ejected its outer layers into space. As the layers of stellar material spread out from the nucleus – the white stellar remnant at the centre of the image – they ended up acquiring unusual shapes.

NGC 6818 features pinkish knotty filaments and two distinct turquoise layers: a bright, oval inner region and, draped over it like sheer fabric, a spherical outer region.

The central star has a faint stellar companion 150 astronomical units away, or five times the distance between the Sun and Neptune. You can just about make this out: if you zoom in to the centre, you’ll notice the white dot in the middle is not perfectly round, but rather two dots very close together.

With a diameter of just over half a light-year, the planetary nebula itself is about 250 times larger than the binary system. But the nebula material is still close enough to its parent star for the ultraviolet radiation the star releases to ionise the dusty gas and make it glow.

Scientists believe the star also releases a high-speed flow of particles – a stellar wind – that is responsible for the oval shape of the inner region of the nebula. The fast wind sweeps away the slowly moving dusty gas, piercing its inner bubble at the oval ends, seen at the lower left and top right corners of the image.

NGC 6818 is located in the constellation of Sagittarius and is about 6000 light-years from Earth. It was first imaged by the Hubble Space Telescope’s Wide Field Planetary Camera 2 in 1997, and again in 1998 and 2000 using different colour filters to highlight different gases in the nebula.
