Participant’s Name _________________________ Categories for the competition: Manual Telescope Electronically Aided Telescope Binocular Astrophotography (best photo) (if you expect to compete in more than one category please fill-out a sheet for each) ** There are four objects on this list that may be beyond the reach of beginning astronomers or basic telescopes. Therefore, we have marked these objects with an * and provided alternate replacements for you just below the designated entry. We will use the primary objects to break a tie if that’s needed.

Flaming Star the Flaming Star Nebula (IC 405) in the Constellation Auriga Is a Surprisingly Colorful and Dramatic Emission/Reflection Nebula
WESTCHESTER AMATEUR ASTRONOMERS January 2016 Image Copyright: Mauri Rosenthal Flaming Star The Flaming Star Nebula (IC 405) in the constellation Auriga is a surprisingly colorful and dramatic emission/reflection nebula. In This Issue . The most prominent star in the image is the variable blue dwarf AE pg. 2 Events For January Aurigae, burning with sufficient intensity to knock electrons off pg. 3 Almanac the hydrogen molecules found in a cloud 5 light years across, pg. 4 Vivian Towers which in turn emit red light. The bluish gray area is not from ion- pg. 5 The Radio Sky ized Oxygen (as found in the Veil Nebula); rather it is mostly a pg. 11 Kepler cloud of carbon dust, which reflects the blue light from the nearby pg. 12 President’s Report star. The result is an emission/reflection nebula 1500 light years distant and accessible from the suburbs with a small telescope. Mauri Rosenthal imaged this from his backyard in Scarsdale with a guided Questar 3.5” telescope over two nights in November using CLS (broadband) and H-alpha (narrowband) filters.

August 2012 of You Know I Went to the Astronomical League Conference (Alcon) in Chicago at the Beginning of July with My Grandmother
BACKBACK BAYBAY observerobserver The Official Newsletter of the Back Bay Amateur Astronomers P.O. Box 9877, Virginia Beach, VA 23450-9877 Looking Up! Hello again! This month I actually have a story EPHEMERALS to tell, instead of just random ramblings. As most august 2012 of you know I went to the Astronomical League Conference (ALCon) in Chicago at the beginning of July with my grandmother. It was great. Not quite 08/24, 7:00 pm as good as last year, seeing as I had to pay for it Night Hike and they didn’t give me a check and a plaque this Northwest River Park year (last year I won the Horkheimer Youth award, which paid for my trip), but it was still a lot of fun, and very educational. I met a lot of cool 08/24, 8:00 pm people and definitely learned something. The Garden Stars whole trip was a big story, but a few events stand Norfolk Botanical Gardens out the most in my memory, and they’re all connected to some extent. 08/28, 7:00 pm Boardwalk Astronomy It all started on the day we got there. ALCon is Near 24th St Stage an annual four day conference usually in the VA Beach Oceanfront beginning of July. This year, the day we got there was July fourth. After checking in, taking a nap and 09/06, 7:30 pm dining, we decided to participate in the observing BBAA Monthly Meeting event outside the hotel. It was in a parking lot with lights, and fireworks, but there was a large moon TCC Campus and Saturn was up, so we went for it. -
Possible Groupings of Irregular (Orion) Variables
POSSIBLE GROUPINGS OF IRREGULAR (ORION) VARIABLES M. V. DOLIDZE Abastumani Observatory, Abastumani, Georgia, U.S.S.R. Abstract. New groupings of Ha-emission stars connected with young clusters, asso ciations and nebulae are considered to be possible regions of clusterings of irregular (Orion-type) variables. They are listed in Table I and an example, No. 19, is shown in Figure 1. Finding charts of individual stars and more detailed data will be given in two forth coming papers in the Bulletins of the Abastumani Astrophysical Observatory.

The list was compiled Featured content by Sir Patrick Caldwell-Moore, better known as Patrick Moore, as a complement to the Messier Catalogue. Current events The Messier Catalogue is used frequently by amateur astronomers as a list of interesting deep-sky objects for observations, but Moore noted that the list did not include Random article many of the sky's brightest deep-sky objects, including the Hyades, the Double Cluster (NGC 869 and NGC 884), and NGC 253. Moreover, Moore observed that the Donate to Wikipedia Messier Catalogue, which was compiled based on observations in the Northern Hemisphere, excluded bright deep-sky objects visible in the Southern Hemisphere such [1][2] Interaction as Omega Centauri, Centaurus A, the Jewel Box, and 47 Tucanae. He quickly compiled a list of 109 objects (to match the number of objects in the Messier [3] Help Catalogue) and published it in Sky & Telescope in December 1995. About Wikipedia Since its publication, the catalogue has grown in popularity and usage within the amateur astronomical community. Small compilation errors in the original 1995 version Community portal of the list have since been corrected. Unusually, Moore used one of his surnames to name the list, and the catalogue adopts "C" numbers to rename objects with more Recent changes common designations.[4] Contact Wikipedia As stated above, the list was compiled from objects already identified by professional astronomers and commonly observed by amateur astronomers. -

Imaging Van Den Bergh Objects
Deep-sky observing Explore the sky’s spooky reflection nebulae vdB 14 You’ll need a big scope and a dark sky to explore the van den Bergh catalog’s challenging objects. text and images by Thomas V. Davis vdB 15 eflection nebulae are the unsung sapphires of the sky. These vast R glowing regions represent clouds of dust and cold hydrogen scattered throughout the Milky Way. Reflection nebulae mainly glow with subtle blue light because of scattering — the prin- ciple that gives us our blue daytime sky. Unlike the better-known red emission nebulae, stars associated with reflection nebulae are not near enough or hot enough to cause the nebula’s gas to ion- ize. Ionization is what gives hydrogen that characteristic red color. The star in a reflection nebula merely illuminates sur- rounding dust and gas. Many catalogs containing bright emis- sion nebulae and fascinating planetary nebulae exist. Conversely, there’s only one major catalog of reflection nebulae. The Iris Nebula (NGC 7023) also carries the designation van den Bergh (vdB) 139. This beauti- ful, flower-like cloud of gas and dust sits in Cepheus.
