WHATS UP FOR SEPTEMBER 2018

CLOSE MARS Image Credit & Copyright: D. Peach, V. Suc, Chilescope team

Still bright in evening skies, Mars was just past opposition and closest to Earth on July 31, a mere 57.6 million kilometers away. Captured only a week later, this remarkable image shows the Red Planet's disk near its maximum size in earthbound telescopes, but still less than 1/74th the apparent diameter of a Full Moon. Broad regional surface shadings are starting to reappear in the tantalizing view as the latest planet-wide dust storm subsides. With the bright south polar cap at the bottom, the Valles Marineris extends along the center of the disk. Just below it lies the roughly circular Solis Lacus region sometimes known as the Eye of Mars. In a line, three prominent dark spots left of center are the volcanic Tharsis Montes.

COMET Taken by Noel Keating on August 31, 2018 @ Ballintra, Co Donegal , Ireland

Comet 21P/ Giacobini - Zinner

I have been keeping a close eye on this comet this past few weeks and was hoping it wont disappoint like so many comets before... so far 21P/ G-Z is far from disappointing, its steadily getting brighter and nicely placed in the sky for northern hemisphere viewers.

This Comet is starting to get bright enough now to be able to include it in landscape photographs. This photo is a 30 second exposure tracked and shot with a 55mm kit lens... Now is the time for people to get out a give capturing this awesome Comet ago..

best of luck for anyone trying...

THE NGC 6914 COMPLEX Image Credit & Copyright: Ivan Eder

A study in contrasts, this colorful skyscape features stars, dust, and glowing gas in the vicinity of NGC 6914. The complex of reflection nebulae lies some 6,000 light-years away, toward the high-flying northern constellation Cygnus and the plane of our Milky Way Galaxy. Obscuring interstellar dust clouds appear in silhouette while reddish hydrogen emission nebulae, along with the dusty blue reflection nebulae, fill the cosmic canvas. Ultraviolet radiation from the massive, hot, young stars of the extensive Cygnus OB2 association ionize the region's atomic hydrogen gas, producing the characteristic red glow as protons and electrons recombine. Embedded Cygnus OB2 stars also provide the blue starlight strongly reflected by the dust clouds. The nearly 1 degree wide telescopic field of view spans about 100 light-years at the estimated distance of NGC 6914.

AURORA Taken by Paul Stewart on August 26, 2018 @ Timaru, New Zealand

Even with the full Moon to contend with, the Aurora put on an awesome show.

GLITTER PATH TO THE SUN Taken by Noeleen Lowndes on August 27, 2018 @ North Stradbroke Island QLD Australia

The golden sunset yesterday afternoon on North Stradbroke Island (Minjerribab) was just so beautiful. As the tide was coming in on the beach at Adder Point I was able to capture a pretty glitter path to the Sun, where you can see hundreds of little Suns reflected in the waves and on the water.

There are many ways to enjoy and capture our amazing Star the Sun :-)

Image was taken with a Canon 70D camera and a Tamron 18-400mm lens set at 70mm and F11, the exposure time was 1/500th of a second and ISO 100.

COMET 21P/GIACOBINI-ZINNER Taken by José J. Chambó on August 12, 2018 @ Valencia, Spain

Comet 21P / Giacobini-Zinner photographed on August 12th 2018 grazing the Milky Way border in Cassiopeia more dense of stars (down). The comet has considerably increased its angular size showing a turquoise color with 9 wich wrapping nucleus. Its dust tail reaches 40 lenght inside within which can be seen a ionic jet more condensed.

Telescope GSO 8 N f/3.8 & Camera Atik 383L+.
12 min. total exposure.

SEA AND SKY GLOWS OVER THE OREGON COAST Image Credit & Copyright: Rudy Montoya

Every step caused the sand to light up blue. That glow was bioluminescence -- a blue radiance that also lights the surf in this surreal scene captured last month at Meyer's Creek Beach in Oregon, USA. Volcanic stacks dot the foreground sea, while a thin fog layer scatters light on the horizon. The rays of light spreading from the left horizon were created by car headlights on the Oregon Coast Highway (US 101), while the orange light on the right horizon emanates from a fishing boat. Visible far in the distance is the band of our Milky Way Galaxy, appearing to rise from a dark rocky outcrop. Sixteen images were added together to bring up the background Milky Way and to reduce noise.
