Saturn is nearing Opposition, and is looking good all night long now…So go out and look it low in the South, Saturn is only ~ 21 degrees above my Southern Horizon in Dayton, Ohio, but still looks great in a telescope.
Here is another Shot this time Close-up of Saturn with the (11th magnitude Icy Geyser moon) Enceladus ,captured on 06-09-2017 from my backyard Observatory in Dayton, Ohio.
I used a Televue 5x Barlow & QHY5IIL Cmos Camera attached to my old orange tube C8, testing the magnification limits of my little 8 inch diameter scope.
The exposure times were longer than usual through RGB filters, as Saturn got very dim when magnifying that much with the 5x Barlow. I can only do this on nights of decent stable seeing, but it was cool to see it fill my screen.
Not bad for being so low on the Horizon and for an object that is 1.275 billion km or ~ 792 million miles away.
Saturn rises after dark in the South East each night, but is at its highest point in the South by about 2:00am …look for that bright Yellow Star due South.
I hope we get many more stable seeing nights during this Saturn Observing Season!
Saturn nearing Opposition…
Seeing was half way decent last night..060917..after 1:00am I captured some close-ups of Saturn near Opposition
…a few more days to Opposition, but you can see the shadow of the Rings on the front of Saturn’s Cloud-tops,
…and also the Shadow of Saturn’s Disk laying across the rings directly behind the top of the disk giving it the “cat ears” look!
When Planetary imaging you have two basic options…shoot with a single shot color Camera, or Shoot with a monochrome(B&W) camera and use a Filter wheel with three primary colors Red, Green, & Blue to combine them later for a full color image. I happen to prefer the Monochrome & Filter wheel, simply because it is a little better at resolving the finer details, but it is more work than with a single shot color camera.
The Best steady seeing I’ve experienced in a while here in the Midwest, the More stable it is the more details I can pull out of the image, hopefully we get more steady nights like this.

Saturn Near opposition 06-09-2017
BTW Saturn is rising low in the Southeast after Dark. Don’t forget to look at Jupiter high in the South right at Dark too!
Sinus Iridum aka the “Bay of Rainbows” is a plain of basaltic lava in the Northwestern portion of Mare Imbrium on Earth’s moon.
It is surrounded by the rugged Mountain Range known as Montes Jura.
Sinus Iridum was formed from the remains of a large impact crater, which was then flooded with basaltic lava, inundating the “sea” wall.
The Bay of Rainbows spans 236km or 146.64 miles across.
If you were to drive across the Bay of Rainbows at 60mph, (assuming no crater sized potholes, LOL!!) it would take ~ 2 hours and 26 minutes.
Roughly the distance from Dayton, Ohio to Versailles, Kentucky, or Dayton, Ohio to Nashville, Indiana.
This bay and the surrounding mountains is considered one of the most beautiful features on the Moon, and is a favorite among lunar observers.
It is one of the features on the Moon that can be seen with the unaided eye.

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.
Caldwell 38 or NGC-4565 Edge on Spiral Galaxy, shining at magnitude 10.4,it is located at 30 to 50 million light years away in the direction of the constellation of Coma Berenices. Nick named the “Needle” Galaxy due its thin edge on profile. It was discovered by Sir William Herschel in 1785.
The central bulge of NGC-4565 is thought to have about 240 globular star clusters hovering around it, far more than our own Milky Way Galaxy.
The really cool thing is that if we were to back away from our own Milky Way galaxy and go about 50 million light years out and then look back we would look similar to this galaxy. The NGC4565 Galaxy is even more luminous that Andromeda, but is about 25 times more distant.
The smaller spiral galaxy to the upper left is NGC-4562, and there are several other little galaxies visible in the background as well.
NGC-4565 Certainly is one of my favorites to look at in my telescopes.
I captured this image from my backyard in the city of Dayton, Ohio with my Celestron 6 inch Newtonian Telescope, & ZWO ASI 174MM Cooled monochrome Cmos Camera with a 2 hour exposure.
Closest Approach of Comet 41P/Tuttle–Giacobini–Kresák at Magnitude 8.6 in the Constellation of Draco.
Comet 41P is still visible in Binoculars from a dark location, it is heading for Perihelion on the 12th of April.
On April 1st – 2nd, the comet passed by Earth at a distance of about 13 million miles (0.14 astronomical units), or 55 times the distance from Earth to the moon; An unusually closer approach for this Jupiter-family comet. Comets are frozen balls of Ice, Gas, & Dust that start to sublimate when heated by the sunlight as they approach the inner solar system.
The green color is the Comet P41 Spewing C2 Diatomic Carbon which glows green when lit by the sun in the Vacuum of Space!
Here is my shot of Comet 41P as it passed within 13 arc minutes of 4.58 Magnitude Star 10 Draconis, & 4.7 Magnitude Double Star WDS HJ 3342 (WDS = Washington Double star Catalog)
Taken with my Homemade 16 inch Diameter Newtonian Telescope and a Canon 6D DSLR,

The Draco Galaxy Triplet, 100 Million Light Years Away in the Constellation of Draco!
If you explore the wide field image you will see several other distant NGC & PGC galaxies.
The Draco Triplet from Top to bottom are NGC-5985 Seyfert type Face on Spiral Galaxy, NGC-5982 Elliptical Galaxy, & NGC-5981 Edge on Spiral Galaxy.

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.

Andromeda & Triangulum Constellations with Spirals! We are looking through all those Milky Way Stars to see our nearby sister Galaxies in the background.
The Milky Way’s Sister Galaxies M31 Andromeda Spiral Galaxy & M33 Spiral Galaxy in Triangulum, also visible are NGC752 Open Cluster, & M34 Open Cluster, on The far left edge in Cassiopeia are the Double Clusters & NGC-281 Pacman Nebula in Cassiopeia. Included is my Illustrated version to help you identify what is in the FOV.

M57 The Ring Nebula in Lyra.
The nebula disk has an angular size of 1.5 × 1 arc-minutes, making it too small to be resolved with 10×50 binoculars, so it is best
viewed with a telescope and under some magnification. I find that 100x works well..
M57 is an example of the class of planetary nebulae known as bipolar nebulae. The star at the Center is Blowing off its Outer atmosphere!
This will be the fate of our Sun in a few billion more years.
I processed this image to show structure in the nebula…
