DAS FOCUS Monthly Newsletter Vol. 57, No. 9, November, 2012 Next Meeting – November 20th, 2012 at 8:00 PM Two Mini-Talks by DAS Members: Harnessing the Full Power of Skytools 3 - Speaker: Doug Norton Winter Observing Gear - Speaker: Fred DeLucia at the Mt. Cuba Astronomical Observatory FROM THE PRESIDENT Bill Hanagan Special 2nd Annual Issue First off, I’d like to thank Greg Lee for his October presentation of “What’s Up” and Mike Cimorosi for his talk and Showcasing the Formidable demonstration on stellar parallax. Thanks also go to Jeff Lawrence for providing refreshments. Because we were running Astro-Photography Talents late, I held my talk on Telescope Collimation for another time. I’d also like to take this opportunity to thank all of of DAS Members! those who have contributed to this special issue of the FOCUS Editor Joe Neuberger FOCUS. Imaging is a major and growing activity in amateur Once again, the response of DAS members has astronomy nationwide and one that several of our members been overwhelming, and the bulk of this month’s issue of the have obviously embraced enthusiastically.

We have members who literally travel the globe in Lee, followed by 2 mini-talks: 1) Harnessing the Full Power order to scratch their itch for recording the heavens and its of Skytools 3, an in-depth guide to getting the most from this majesty. And this month we are treated to a wide variety of observing and astro-photography planning tool, by Doug Norton; their efforts in the feature beginning on page 10. and 2) Winter Observing Gear, a guide to keeping warm and And, as I stated in the October issue’s happy while observing in cold weather, by Fred DeLucia. “Last Word” column, there’s nothing I admire more in this As always, I’d like to remind you to keep thinking club of amateur astronomers than those who experiment about how YOU can contribute to the DAS and how you can with the evolving technologies related to, and place consider- make the DAS a better astronomy club. We’ve had some able resources into the exploration that is the art of modern volunteers step forward, and we’ve received a variety of AstroPhotography. I salute each and every one of the equipment donations, but more volunteers and donations are participants in this month’s endeavor and look forward to always needed. In particular, we still have empty slots featuring more of their efforts in the issues ahead. for about 4 mini-talks in our speaker schedule.

DAS Member Star Parties (MSP’s) Bill Hanagan The DAS MSP held in conjunction with the Fall “No-Frills” Stargaze on October 11-14 was a great star party once again this year and is described in a separate report along with photos beginning on page 5. A week later, on October 20, we held our 10th MSP of the year, this time at the Sawin Observatory. DAS members Mike Cimorosi, Randy Detra, Diana Metzger, and myself were present—and we had a great time! We observed primarily what I consider to be the showpiece objects for this time of year, most notably M13, M92, Albireo, M57, the coat hanger, the Double Cluster in Perseus, M31 and M32, among other objects. Earlier in the day, at around 4 PM, the sky was beset by a heavy haze and thin clouds. But, as forecast, the sky cleared completely by 7:30 PM and remained clear until closing. This is yet another example of how the MSP program, which uses weather forecasts and email for scheduling, has enabled us to hold star parties on clear nights in spite of rather bleak conditions earlier in the day. “GO” has been called for more than 30 potential MSP nights in the last 3 years and we’ve had only two occasions that I can remember when observing was seriously impeded by clouds. And, in one of those cases, we were able to observe many of the showpiece objects in spite of persistent haze and wispy clouds. The moral is this: don’t let a bleak daytime sky convince you not to come out to one of our MSPs. If the MSP supervisor issues a GO, it’s an excellent bet that the sky will actually be clear for the MSP, even if it isn’t already clear. Coming up in November, we’re planning to hold the Fall Messier ½ Marathon MSP on either the weekend of The Messier November 9 / 10, or November 16 / 17. As in years past, the Chart of objects at right are the event will be held at Gus Swartout’s Elk River site south of targets sought Elkton, MD. Gus will be the MSP supervisor for the event.

Inside, you’ll find several opportunities to reach out to the community and share the wonders of the night sky, even from our heavily light- polluted neck of the woods.

  • JANUARY 2016 M78 – NGC-2068 – Bright (Reflection) Nebula in Orion M78 Is a Reflection Nebula That Lies in the Constellation of Orion
    MONTHLY OBSERVER’S CHALLENGE Las Vegas Astronomical Society Compiled by: Roger Ivester, Boiling Springs, North Carolina & Fred Rayworth, Las Vegas, Nevada With special assistance from: Rob Lambert, Las Vegas, Nevada JANUARY 2016 M78 – NGC-2068 – Bright (Reflection) Nebula In Orion M78 is a reflection nebula that lies in the constellation of Orion. It was discovered by Pierre Méchain in 1780. Charles Messier added it to his catalog the same year. It’s part of the same complex nebula cloud that includes the Orion Nebula, M42/43. It lies about 1,600 light-years away and shines at a relatively easy mag. 8.3. It’s easy in most back yard telescopes. What may be a bit more difficult are the surrounding patches of nebulosity that include the strip called NGC-2067, an extremely faint patch called NGC-2064 and a little further away, the faint but large smudge NCG-2071. All four objects can fit within the field of a decent wide-field eyepiece. Observations/Drawings/Photos (Contributors listed in alphabetical order) Glenn Chaple: LVAS Friend and Author from Massachusetts I first saw M78 on January 20, 1977, using a 3-inch f/10 reflector at 30X. I noted that it appeared small with what seemed like a concentrated nucleus. I next viewed it on March 24, 1998, this time with a 3-inch f/6 reflector at 57X (see sketch and notes). Earlier this month, I revisited M78 with my 4.5-inch f/8 reflector and a friend’s 18-inch f/5 reflector. It had an eerie appearance – a pair of mag.
