President’s Message – Mar 2022

Posted by as President's Message

What is it that links our community together? Every year, we recognize a few members of the Victoria Centre and present them awards of appreciation and excellence. We announced the recipients at the Annual General Meeting. I had the pleasure last week of driving around Victoria handing out their framed certificates. I enjoyed seeing these stellar members of our community in their home settings. It is one of the great privileges of being president. Everyone was proud and delighted, and often surprised at the recognition. We are far greater than the sum of our parts. These members have gone an extra length to make our community stronger and more active. Thank-you!

Awardees (clockwise from top left): John McDonald, Chris Purse, Alec Lee, Bruce Lane, Barbara Lane, Cameron Burton.

We have a wide range of backgrounds and interests. We spend our time with a variety of aspects spanning the range of amateur astronomy. I particularly like the feeling of connection with people around the world and throughout time. Some are interested to produce the best image of an astronomical object. Some are keen to know their way around the constellations.

There is a huge hunger for astronomical knowledge out there in the bigger public. This was made very clear this last week with front page articles and television features about our friend and astro- buddy Sid Sidhu; on the occasion of having an asteroid named after him. Sid has been central to our public outreach and society in- reach activities over a period of decades!

What is it that links our community together is that the wonders of the sky fill us with awe and with pleasure.

Look Up,
Randy Enkin (email)

Video transcript of the meeting

Deborah Lokhost presented to us about the Dragonfly Telephoto Array. She is an Instrument Science Research Associate at the NRC Herzberg Astronomy and Astrophysics Research Centre in Victoria, BC. During her PhD in the Department of Astronomy and Astrophysics at the University of Toronto, she worked with the Dragonfly Telephoto Array to observe and study galaxies. She designed an upgrade to Dragonfly and built a pathfinder telescope based on this design which she then used to study gas in the surroundings of galaxies. She is currently leading the construction of a full-scale upgrade to the telescope which has the ultimate goal of imaging gas in the “cosmic web” of dark matter.

Dragonfly Telephoto Array

  • Reasons for Dragonfly
    • Large galaxies with low luminosity (surface brightness)
    • Light scattering is the main problem
    • Reflecting telescopes don’t help, since they scatter light
    • Refractors have a limit in size
  • Design
    • Canon using nano coatings to reduce light scatter for their long telephoto lenses
    • Using 48 Canon EF 400mm f/2.8L – split between two Paramounts/observatories
    • Mexico Skies Observatory – site
    • Astroplanner – mission planning and execution
    • Been in operation for 6 years
    • Comparison between Dragonfly and Sloan Digital Sky Survey
    • Diffraction Limited SBIG CCD cameras
    • Intel stick computers talk to a master computer for data collection
    • Filter 1/2 G and 1/2 R (Sloan clone)
  • Science
    • Main target is galaxies
    • What is Dark Matter? 90% of the Milky Way is Dark Matter
    • Dark Matter first detected by Vera Rubin
    • Ultra Diffuse Galaxies – new discovery by Dragonfly team
    • Looking for Globular Clusters in these ultra diffuse galaxies
    • First field images – Coma Berenice cluster of galaxies
    • NGC 1052 diffuse galaxies – very little Dark Matter – unusual!
    • Modified Newtonian Galaxy – alternate theory to Dark Matter
  • What about outside galaxies? – Deborah’s main study
    • Detecting faint gas emissions using ultra-narrowband filters
    • Simulated Ha observations from EAGLE cosmological simulation that should be possible using Dragonfly
    • Mounting the ultra-narrowband filters in front of the lenses would improve the result, and tilting the filter improves performance
    • Discovered a new Ha shell around M81/M82
    • 0.8nm filters will be used on new array
    • 30 new lenses to start with for testing and fine tuning

President’s Message – Feb 2022

Posted by as President's Message

Randy Enkin

A colleague recently told me that my family name, Enkin, in Japanese literally means “near-far” (遠近). One sense of the Japanese word “enkin” is “perspective”; another is “bifocal glasses”. My colleague flatteringly suggested that if we could get some of our other colleagues to spend time wearing Enkin glasses, we could probably quickly achieve consensus regarding a scientific controversy that we have been involved in for the last 30 years.

One of the joys of astronomy is using our knowledge of what is near to help us understand what is far. For me, my training as a geologist gives me a fair amount of knowledge concerning how the earth works and this informs my way at looking at astronomical objects. In my Astro Café presentations, I try to help the rest of you to see my perspective on various astronomical topics.

Everybody in the Victoria Centre has something important to contribute. You all have your personal interests and experiences, which informs what you see and understand in our common interest of astronomy. It would be wonderful to hear more of you at the Astro Café. I am quite sure our wonderful SkyNews editor would love to receive more articles for this newsletter! Presentations do not have to be polished, nor original. Your perspective is what we value. In my experience, I see that we are a particularly patient and accepting audience.

So, put on some Enkin glasses. Take joy in what you see and share it with our community. We will all learn to see your subject with a new perspective, and we will gain a better appreciation of each other.
Thank you all for accepting and supporting me through my first year as President of the Victoria Centre. It is an honour to be part of this long-running institution. I look forward to year two, with lots more activities – sometimes even in person! I look forward to getting to know more of you and sharing our mutual appreciation of the wonders of the sky.

Look Up,
Randy Enkin, President@Victoria.RASC.ca
