What's In The Sky - June 2019

Get ready for summer stargazing! With the weather warming up, June is a great time of year to enjoy relaxing evenings under starry skies with your telescope or astronomy binoculars. Here are a few of Orion Telescopes and Binoculars' top picks for June 2019 stargazing:

Jupiter at Opposition

Jupiter shines brightly in the constellation Ophiuchus during June and will be in opposition to the Sun on June 10. Around the same time is also its closest approach to Earth, making it an ideal time for observation. Use a SkyQuest XT6 PLUS Dobsonian along with the 10mm Plossl eyepiece and Shorty 2x Barlow lens that comes with it to get views of the largest planet in our solar system at 240x magnification! Or, pair it with the Orion StarShoot 1.3mp Solar System V Imaging Camera for an affordable planetary imaging system!

Summer is the Globular Season!

Globular star clusters are densely packed balls of stars that are concentrated toward the center of the Milky Way. June skies offer some of the finest globular cluster viewing opportunities. While you can detect most globular clusters in 50mm or larger binoculars, a moderate to the high-power eyepiece in a 6" or larger telescope offers the best chance to resolve individual stars. In the constellation Hercules, look for M92 and the “Great Cluster” M13. In Scorpius, look for M4 and M80. The constellation Ophiuchus is home to six globulars – M10, M12, M14, M107, M9, and M19. Can you spot them all?

The Virgo Cluster

A treasure trove of galaxies can be explored if you point your 6” or larger telescope toward the Virgo Galaxy Cluster. The Event Horizon radio telescope array released the first image of a black hole in April, of the supermassive black hole in M87. While the black hole might need an Earth-sized radio telescope array to resolve it, the galaxy itself can be viewed with more affordable equipment. Aim your telescope at M87 in the constellation Virgo and start scanning the surrounding night sky. How many galaxies can you see?

Summertime Star Party

Take advantage of the New Moon on June 3rd and the galaxies and globular clusters visible to put on a star party! Not only will the dark skies of the moonless night provide great opportunities to see fainter objects more clearly, but the warm June weather will make it easy to enjoy starry sights all night long with friends and family.

Swirling Spirals

Around 10pm in mid-June, two glorious, face-on spiral galaxies M51 and M101 will both be in a great position for viewing and imaging. Look for M51, the Whirlpool Galaxy, to the southwest of the star Alkaid at the end of the Big Dipper's "handle". Scan the sky to the northeast of Alkaid to find M101, the Pinwheel Galaxy. Under very dark skies, these distant galaxies can barely be detected in smaller telescopes, but a 10" or larger reflector will reveal much more impressive views. If you're viewing from an especially dark location, try to resolve the delicate spiral arms of M51 in a 10" or larger telescope.

Gems of the Summer Triangle By 10pm in mid-northern latitudes, the Summer Triangle, comprising beacon stars Vega (in Lyra), Deneb (in Cygnus), and Altair (in Aquila), will be fully visible above the horizon. Several celestial gems lie within its confines, including the Ring Nebula (M57), the Dumbbell Nebula (M27), open star cluster M29, and the visually challenging Crescent Nebula (NGC 6888). To catch a glimpse of the elusive Crescent, you'll almost certainly need an Orion Oxygen-III Filter in a larger telescope.

Summer Sky Challenge Discovered in 1825 by the German astronomer Friedrich Georg Wilhelm von Struve, NGC 6572 is bright enough to be seen in a humble 60mm refractor telescope from a dark sky site; but it is very, very small! At only 8 arc seconds in size, it takes a lot of magnification to distinguish this from a star. The easiest way to find it is to look in the target area for a green star. NGC 6572 is one of the most intensely colored objects in the night sky. Some say this is green, and some say it is blue; what do you think?

All objects described above can easily be seen with the suggested equipment from a dark sky site, a viewing location some distance away from city lights where light pollution and when bright moonlight does not overpower the stars.

Annual Visit to SkyPi Remote Observatory

Its that time of year again! Insight Observatory Systems Engineer, Muir Evenden and I are onsite at SkyPi Remote Observatory in Pie Town, New Mexico performing annual maintenance and systems upgrades to the Astronomical Telescopes for Educational Outreach (ATEO). Since we installed the 16" f/3.7 astrograph reflector, ATEO-1, exactly two years ago this month, we have been running the remote robotic telescope entirely with a Raspberry Pi. Although the Pi was very dependable to run the entire imaging system, we figured it was time for an upgrade. We successfully installed a Fitlet 2 Mini PC installed with Linux to run the ATEO Portal software that is integrated with The SkyX. With the upgrade in memory to 4GB and the 64GB external USB storage devices, we have noticed a difference in speed performance. The Raspberry Pi will remain in place for redundancy.

Another priority item on the "to-do" list on our visit is the collimation of the telescope's mirrors. The last time we performed this was on our last visit a year ago. Fortunately, we have found it necessary to only perform collimation only once a year so far. However, if collimation needs to be done again before our next visit in 2020, the reliable staff at SkyPi Remote Observatory is there to perform the task if needed in our absence.

Another important task to be completed was by installing a new flat field table in the Gamma observatory where the ATEO-1 imaging system is housed. Muir has been successfully acquiring sky flat fields in the past at twilight using a script he wrote, however, although that method was successful, it can be tricky at times. John Evelan, Managing Member of SkyPi Online Observatory, LLC, was gracious enough to install an LCD backlit flat field table on the observatory wall for our use. Other items on the list of tasks for ATEO-1 completed consisted of adjusting the shutter on the Proline 16803 CCD camera, LRGB, V filter inspection, performing a T-Point adjustment in the SkyX, focusing the guide scope and having a tree-topped that obstructed the southern view from the observatory.

After our chores are completed with ATEO-1, we will be moving on to our affiliate remote robotic telescopes, ATEO-2A and ATEO-2B. We will be working with John, who owns the Williams Optics 5" f/7 refractor, ATEO-2A, and the Celestron 11" f/10, ATEO-2B dedicated planetary telescope. John and his staff at SkyPi have a fully modified Omega observatory where both telescopes are tandemly mounted on a Software Bisque GT1100S mount. We will be working on integrating those two imaging systems into the ATEO Portal as well as Insight Observatory's new "Starbase" dataset library that is currently in development to be released in mid-June 2019.

Total Lunar Eclipse Imaged From ATEO-1

Here is a project Insight Observatory hadn't planned on doing with the 16" f/3.75 Dream Aerospace Systems astrograph reflector telescope (ATEO-1). However, with interest from other Astronomical Telescopes for Educational Outreach (ATEO) users on how the January 20th - 21st total lunar eclipse of the moon would look through this telescope, what was there to lose by spending some time trying to capture the lunar eclipse during totality? Nothing gained if nothing ventured.

Now... If you recall... Insight Observatory's ATEO-1 imaging system is configured primarily as a deep-sky imaging platform, so we didn't know whether the moon would be too bright (even at totality) for its fast f-ratio and fastest CCD camera shutter speed. In addition, the Proline 16803 CCD camera is outfitted with a color filter wheel on a monochrome camera, therefore we had to switch filters quickly between the short Luminance, Red, Green, and Blue (LRGB) exposures.

Would all this come together? The short answer was a surprising yes! Unfortunately, we didn't get a chance to optimize the focus before imaging, but I think our results are entirely satisfactory considering what we knew beforehand.
