Jupiter & 3 Moons

Jupiter with 3 moons Europa, Io, & Ganymede, The GRS (Great Red Spot) was getting ready to go around the Limb, the 4th Moon Callisto was way off the field of view!

The Great Red Spot (GRS) is a persistent anticyclonic storm, 22° south of Jupiter’s equator. observations from Earth establish a minimum storm lifetime of 350 years.

The GRS winds speeds top out at about 400mph.. and is 2 to 3 times the size of the Earth!

I tested out the ZWO 224MC single shot color camera on my 8inch SCT to see what it can do, …Seeing was okay at prime focus, but any magnification you could see the Earth’s atmosphere boiling. so will try to Barlow it up on the next night of stable seeing.

Jupiter near Spica in Virgo!

Take a look at the Planet Jupiter above Spica…Jupiter is the Brightest point of light in this image, shining at -2.0 magnitude.

If you look due South at 6:30am to 7:00am over the next few weeks you will see The Planet Jupiter above the Brightest Star in Virgo – Spica.

Over the next few months the pair stay nearby each other.  This can be easily seen, even in the city., so go take a look!

It was so nice to See Jupiter near Spica in Virgo early this morning (12-27-2016) looking due South over my neighborhood in Dayton, Ohio. Visible are the Constellations of Virgo, Libra, Corvus, & Crater.

I was pleasantly surprised at how transparently clear it was all the way to the southern Horizon this morning.  I could see a couple of the Stars in the Southern constellation of Centaurus, usually they are buried in the Light pollution & muck on the Horizon, but were clearly visible.

I also included an illustrated version to help you ID the Planet Jupiter along with the constellations and their brighter stars.

Jupiter on 04-18-2016

Jove the Gas Giant Planet!
Jupiter is the fifth planet from the Sun and the largest in the Solar System.
It is a giant planet with a mass one-thousandth that of the Sun, but two and a half times that of all the other planets in the Solar System combined.
Basically you can fit all the planets into Jupiter at the same time with lots of room to spare.

Jupiter rotates every 9 hours &  56 minutes, that is roughly a 10 hours day compared to our 24 hour day here on Earth.
It takes Jupiter 11.86 years to orbit the Sun once, compared to 365 days it takes Earth to orbit our Sun once.
Currently it is 442.8 million miles from Earth…this changes constantly as both Earth and Jupiter orbit the Sun.

Jupiter’s Atmosphere is the largest planetary atmosphere in the Solar System.
It is mostly made up of molecular hydrogen and helium in roughly solar proportions; other chemical compounds are present only in small amounts and include methane, ammonia, hydrogen sulfide and water.

You can find Jupiter with just your eyes nearly straight over head around 10:00pm, it will be the brightest thing straight over head, so go out and take a look tonight, you can even see its clouds bands & 4 Galilean moons with a pair of Binoculars or small telescope held steady or placed on a tripod.

I captured this image of Jupiter on 04-18-2016 centered on (17th 10:26pm EST)  02:26 U.T., We finally got a good night of stable seeing 7/10 from my backyard Observatory in Dayton, Ohio. I was able to crank the magnification up a bit, by using the 3x barlow.  I used my 8 inch diameter(old Orange tube C8) SCT telescope, 3x Cemax Barlow & and a QHY5IIL Mono CCD camera, Astronomik RGB Filters, IFW Filter wheel, Registax6 2400 RGB frames stacked & wavelets, MaximDL for RGB Alignment, Adobe CS 2015 final processing.

I’m happy with the cloud top details…considering we don’t get the greatest seeing here in the Midwest!
I did notice that the Great Red Spot is not so Red anymore, more like Salmon colored Spot…but it still was cool to see some detail within the GRS & cloud top details!

To learn more about Jupiter’s Atmosphere take a read about here…

6 Planets Align & Moon

Everyone is talking about the 5 Planets Aligning in the Morning sky,
But I Captured 6 Planets!!! You have to count the Earth too! LOL!!! Earth provides us this perfect view of the Planets Aligning along the Ecliptic..
The Moon joined these Planets at Dawn last Saturday Morning 01-30-2016 at 6:13am E.S.T. from just outside of Warrenton, Virginia. I included the Earth #6 in this slightly cropped fish-eye Lens shot. Canon 6D DSLR & 8mm Fish-eye Lens, ISO 800, 8 second exposure. Just before the clouds started interfering…

I included an illustrated view to help you all ID them, as well as 3 of the brightest stars. you may also recognize the Constellations of Scorpius, Virgo, Libra, and Corvus are easily visible too. Mercury is a challenge as you have to catch it just before dawn gets too bright! You can see Mercury, Venus, Saturn, Mars, & Jupiter with your eyes only, no telescope needed, just use my diagram to help you find them over the next week or so. Look between 6:00am and 6:45am.

Note: depending when you look the next 2 weeks, the moon will not be there or may not be in the same place, as it moves 12 degrees every day.

Venus & Jupiter Rising!

Venus & Jupiter Rising! A really Low Morning Conjunction Urban Style!!! Jupiter is at Top, Venus Below! All kinds of obstacles when you live in a city, but I still try! If I waited until they cleared all the Obstacles then it would be daylight and not show up very well again the bright blue sky! Canon 6D & 70mm lens, F7.1, ISO 1250, 0.80 second exposure. From my Backyard in Dayton, Ohio on 08-19-2014.

Magical Twilight & Starry Skies in Alaska!

There is something magical about Twilight in Alaska….It made for some very interesting shots!
I must have taken over 50 of these types of shot each night..killing time until it got dark and as we waited for
Magnetic Midnight to roll around(~1:30am) when the Aurora got really super active here in Alaska.

Here we are at 2880 ft. Altitude with super dry cold air after Sunset into Twilight, the blue sky mixed
with the stars & planets, fading daylight/Civil twilight ~9:30pm into Nautical twilight (~10:30pm) then into
Astronomical twilight by about 11:30pm. It did not get real dark here until after midnight…each night.

Here we have the Stars of the Constellation of Orion on the Horizon, between the trees…We have the Pleiades & Hyades Stars Cluster to the right, and to the Left we have bright Star Arcturus  and at the top of the Frame we have the bright Planet Jupiter!!! There is enough light from twilight to keep the snow illuminated for a nice foreground and excellent tree Silhouettes!
