VIdeo frame of ISS taken through an 8″ Dobsonian by Nathan
  • ISS photo – Nathan Hellner-Mestelman
    • Used a iPhone mount using a 30-min video slow motion through a 5mm  eyepiece, 2.5x Barlow and 8″ Dob (1,200mm f/l), so about 600x magnification, 2-3 arc secs 
  • Astronomy Day on May 15th – Randy Enkin & Lauri Roche
    • We were so fortunate to have a clear sky for this online event
    • Reviewed all the presenters and thanked everyone
  • Spectroscopy – Tom Field
    • Intro by David Lee
    • 70-80% of astronomical research is done with spectroscopy
    • Rspec-Astro.com – spectroscopy software for amateur astronomers
    • Bunsen invented his burner to burn elements to see their component spectra
    • Emission and absorption lines in spectrum
    • “The Computers” Annie Jump Cannon – they created categories for spectral plate analysis
    • Equipment to use for capturing spectrum
      • Star Analyser Grating – US$195
      • Other adapters and gear available
      • A slit instead of a grating, which yields more resolution, but costs more and requires better technique
    • Compared spectra of 8 different stars – Torsten Hansen
    • Doing science
      • Graph the results
      • Spectroscopy is more immune to light pollution than traditional astrophotography, so urban observing works
      • Wolf-Rayet stars (WR140) – shows this late-stage star with carbon-rich spectra
      • Spectra can be measured of: planets, comets, meteors, the Sun, Supernova, stars
      • Measuring Doppler Shift, or is it red/blue shift?
      • Extended objects like nebulae need a slit instead of a grating
      • Black Hole? no, but the accretion disk emits light
      • Calculating red shift
    • Spectroscopy can reinforce other observational skills
    • Distance between sensor and grating needs to be precisely setup
    • Emission versus absorption lines
    • Can use other grating, since RSpec can calibrate to other grating resolutions. RSpec grating uses 100 lines/mm which is easy to use, and yields brighter spectra.
    • Calibrate on a known star, then study other objects

Notices

  • There is no Astro Cafe next Monday due to the Victoria Day holiday. The next Astro Cafe is scheduled for May 31st.
  • If anyone would like to lead a citizen science group, please contact David Lee
  • Total Lunar Eclipse is coming up on May 26th

50th Anniversary of Apollo 11

Posted by as Events, Special Events

July 20th marks the 50th Anniversary of the Apollo 11 Moon Landing. Due to media attention a desire to take a closer look at the Moon may grow as this date approaches. Unfortunately the Moon will not rise until 11:14PM on the anniversary of the landing. As a result the International Astronomical Union is organizing a global lunar observing event on July 12th called “On the Moon Again”. Between 8PM and 11PM on Friday July 12th, members of the Victoria Centre of RASC will set up telescopes in Oak Bay at the Cattle Point Dark Sky Urban Star Park. If weather permits they will be happy to share views of the Moon with you.

Apollo 11 astronauts on the Moon

Victoria Centre telescopes will also be in position at the Dominion Astrophysical Observatory every Saturday evening in July from 7:15PM to 10:45PM for weekly Star Parties. These events, co-hosted with The Friends of the DAO, will include the following Moon related lectures:

July 6th: The Voyages of Apollo by Dr. Philip Stooke
July 13th: “Explore the Moon: My 50-Year, 30-Year, and 1-Year Projects” by Randy Enkin
July 20th: The Apollo Moon Walk by Dr. Chris Gainor
July 27th: Through the Knowledge Network: Space Suite Apollo and Space Suite IV

In addition to the above programs these Star Parties also include tours of the historic Plaskett Telescope, the Centre of the Universe Museum and Planetarium shows. Obtain free tickets to the Saturday Star Parties at the Dominion Astrophysical Observatory.

During the week of the July 20th the Friends of the DAO will hold the following additional lectures on Apollo at the Dominion Astrophysical Observatory, starting shortly after 7:00 PM.:

Tuesday July 16: Canada’s Contributions to Apollo by Dr. Chris Gainor

Wednesday July 17: Apollo in the Age of Aquarius by Dr. Dennis Crabtree

Thursday July 18: The Voyages of Apollo by Dr. Philip Stooke

The Centre of the Universe at the DAO will also be open to the public from 10 AM to 3 PM on Tuesday July 16 through Friday July 19.

Here is more detailed information of the scheduled Saturday Star Party lectures at the DAO:

July 6th 2019 – 8:30pm repeats at 9:30pm
The Voyages of Apollo
Dr. Philip Stooke

Abstract: A summary of the Apollo Program including its origins, steps along the way to the Moon, the choice of landing sites and a pictorial look at each mission.

Bio: Phil Stooke is a planetary scientist and cartographer with a PhD from UVic. He taught in the Centre for Planetary Science and Exploration at Western University in London, Ontario until his recent retirement. He has published The International Atlas of Lunar Exploration and similar books on Mars, and is currently revising his lunar atlas.

July 13th 2019 – 8:30pm repeats at 9:30pm
“Explore the Moon: My 50-Year, 30-Year, and 1-Year Projects”
Randy Enkin

Abstract: In 1969, at age 8, the Apollo missions motivated me to become an astronomer. Very quickly I mastered the subject, but then over the following 50 years I mostly found out how little I know. In this presentation, I will present my 30-year time series of lunar phase observations, and my lunar sketches from the past year which earned me the Royal Astronomical Society of Canada “Explore the Moon Observing Certificate” (https://www.rasc.ca/observing/explore-the-moon-observing-certificate). And you will be introduced to “Enkin’s Daily Moon” where images of the moon explore “the passage of time, illumination, the feminine, and world unity”. (https://www.facebook.com/EnkinsDailyMoon/)

Bio: Randy Enkin did not become a professional astronomer. He is a Research Scientist at the Geological Survey of Canada, working on earthquakes. He is an enthusiastic member of the Victoria Centre of the Royal Astronomical Society of Canada.

July 20th 2019 – 7:45pm to 10:45pm
The Apollo 11 Moonwalk with Dr. Chris Gainor

Abstract: This presentation will show the entire Apollo 11 moonwalk as it was televised on the evening of July 20, 1969, along with descriptive slides. Chris Gainor will discuss the flight of Apollo 11, the symbolic aspects of the first walk on another celestial body, and the scientific work carried out by astronauts Neil Armstrong and Buzz Aldrin on the lunar surface. The presentation will begin shortly before 8 p.m., just as it did in real time in 1969, and will continue for the two hours and 40 minutes of this historic event.

Bio: Chris Gainor is a historian specializing in the history of space flight and aeronautics. He has five published books and is currently writing a history of the Hubble Space Telescope for NASA. He is President of the Royal Astronomical Society of Canada.

July 27th 2019 – 8:30pm to 10:45pm
Through the Knowledge Network: Space Suite IV and Space Suite Apollo

Producers – Imagine Create Media
Space Suite IV
A series of 10 short films that explore the infinite wonders of our universe and our interactions with the cosmos.
Space Suite Apollo
Trace the history of NASA’s Lunar missions from Mercury to Gemini, to the Apollo Missions that ultimately landed a man on the moon. Set to the music of Johann Sebastian Bach, Space Suite Apollo gives viewers an unflinching look at the raw footage that continues to capture the world’s imagination.
