What's In the Sky - January 2019

January kicks off the New Year with wonderful sights for backyard astronomers to enjoy with friends and family. Don't forget to bundle up on clear, cold evenings as you explore the sparkling night sky. Here are a few of Orion Telescopes and Binoculars highlights for January 2019 stargazers...

Quadrantid Meteor Shower

The Quadrantid Meteor Shower will be the first substantial meteor shower of 2019. You'll want to be outside late in the night on January 3, and before dawn on January 4. Those of you in the more northerly latitudes should get some great views, especially with the dark skies as we approach the New Moon on January 6.

New Moon

The nights around January 5 will be the best nights for observations due to the dark skies resulting from the New Moon. Bundle up, grab a telescope and your astrophotography gear and get out there to view and image those elusive fainter deep sky objects.

Total Lunar Eclipse

January 20 — 21 will be your opportunity to witness a Lunar Eclipse. Provided your skies are clear, observers in North and South America and western parts of Europe and Africa should have visibility of a Total Lunar Eclipse. While those of you in Central and eastern Africa, Europe, and Asia won't see a Total Eclipse, you will still see a Partial Eclipse of the Moon.

The conjunction of Venus and Jupiter

Get up early (before sunrise) on January 22 to catch the conjunction of Venus and Jupiter. These 2 bright celestial bodies will appear within 2.5 degrees of each other so make sure you don't miss the view.

January Challenge Object

Just west of Rigel, the bright blue/white star that marks the western "knee" of Orion, lies the Witch Head Nebula (IC 2118), in the neighboring constellation Eridanus. The Witch Head is a reflection nebula that shines from reflected light off of Rigel, like the reflection nebula in the Pleiades, M45. You don't need a big telescope; a wide field of view, low power, and a dark sky are needed to see this challenging nebula. (Hint: Don't use filters)

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.

Featured Deep-Sky Object - NGC 2403

It's been a while since we profiled a deep-sky object on our blog, as we have been working hard on getting our affiliate remote robotic telescope, ATEO-2, operational for educational and public use. As Insight Observatory's Project Developer, Michael Petrasko, was preparing a list of deep-sky wonders to possibly image with a class using the Astronomical Telescopes for Educational Outreach, ATEO-1, and ATEO-2, he came across an interesting galaxy in the inconspicuous constellation of Camelopardalis that may be of interest.

The constellation contains no bright stars, but some interesting galaxies wait for observers that happen to point their instruments in this part of the sky. One of these galaxies is NGC 2403, the showpiece of Camelopardalis. NGC 2403 (also known as Caldwell 7) is an intermediate spiral galaxy. NGC 2403 is an outlying member of the M81 Group and is approximately 8 million light-years from Earth. The object has a striking similarity to M33, The Triangulum Galaxy being about 50,000 light-years in diameter and containing numerous star-forming H II regions. The northern spiral arm connects it to the star-forming region NGC 2404.

NGC 2403 can be seen easily as a large hazy spot in 10x50 binoculars, and a telescope will show a bright elliptical haze surrounded by a faint outer halo. A definite degree of mottling becomes apparent with larger telescopes, the effect of dust scattered throughout the spiral arms.

Anyone can image this galaxy and other deep-sky wonders by signing up for an account on Insight Observatory's online ATEO Portal or by using our Public Image Request (PIR) form.

ATEO-2 Doubles Up!

Insight Observatory's affiliate telescope ATEO-2 (owned by SkyPi Remote Observatory) which was originally set up solely with a Williams Optics 5" f/7 refractor now has a companion. The staff at SkyPi Remote Observatory has installed a Celestron 11" Schmidt-Cassegrain Telescope (ATEO-2B) to the same mounting system in the observatory. The 11" SCT is planned to be used primarily for remote planetary imaging. The crew at SkyPi has also been working tirelessly, testing and fine-tuning the mounting system as well as making modifications to the observatory, designated as Omega that houses ATEO-2. The Williams Optics 5" refractor (ATEO-2A) imaging system is now back in operation after it needed to be disassembled to add its companion, the Celestron 11".

The planetary imaging system will be equipped with an Optec Focuser and Celestron Skyris 236C Color CMOS Camera. The timeline for the availability of this imaging setup is planned for February 2019. However, being that the 5" refractor is now available, John Evelan, managing partner at SkyPi Remote Observatory, has thoroughly tested the imaging system from his home in Mesa, Arizona. John acquired some imaging data of M38 and NGC 1907 open clusters in the constellation Auriga on the night of December 5th, 2018. This data was taken with the Starlight Xpress SXVR-M25C color CCD camera that replaced the ATIK 490EX Color camera that was originally installed on the refractor. Although the ATIK performed well, we collectively agreed the wider field of view on the SXVR-M25C would be more impressive.

ATEO-2 will be accessible on the ATEO Portal in the near future, however, it is now available via Insight Observatory's Public Image Request Form (PIR) and Educational Image Request Form (EIR) for gathering astronomical images from the classroom.
