Scanning the Milky Way: Identifying High Energy Sources in our Galaxy

NGC 6388 – X-ray and Visible Composite Image. X-ray: NASA/CXC/IASF Palermo/M.Del Santo et al; Optical: NASA/STScI

How different are the stars we see in the night sky? How do we know their size, temperature, distance, and whether these are just ‘normal’ stars or more exotic light emitters? In this talk, I will be discussing parts of my research dedicated to identifying the most interesting stellar objects in our galaxy. First, we will overview the types of stars we expect to see in the galaxy and how we identify aspects like their temperature, distance and size as astronomers. Then we will introduce how binary star systems greatly alter the ‘expected’ behaviour of stellar properties and end with the role of these system’s in uncovering the Milky Way’s past.

How to Use A Telescope

Do you need help using your telescope? It’s a common complaint among first-time telescope owners: “I’ve got this new telescope and I can’t see a thing through it”. The aim of this Astro Café is to help you get the most out of your new telescope.

Bring your telescope to this Astro Café and experts from the RASC will help you learn how to use it. Let us show you how to make the most out of your telescope. Discover how to properly set up your telescope, how to find objects in the sky, what accessories would be useful to you and how to take care of your telescope.

This Astro Café starts later in the evening, so that if skies are clear, we can head outside and we will have the Moon and Jupiter as bright targets to view through your telescope.

My Personal Five-Year Chase of NLC/Searching for NLC with Airport Cameras

My Personal Five-Year Chase of NLC/Searching for NLC with Airport Cameras

Presented by RASC members Mike Noble and Mark Zalcik.

Noctilucent clouds (NLC) are a sky-high phenomenon best-suited for observing right here in northern Alberta. The ideal dates to look for them are mid June to mid July, so come and celebrate the start of NLC peak season on June 23! The evening kicks off with a brief overview of NLC. Next, learn about Mike Noble’s earnest NLC-searching regimen, driving to many sites to catch NLC displays with his bevy of cameras. Then find out about searching for NLC on images generated at numerous airports across the country. If the weather looks good, stick around for evening twilight and we’ll collectively scan the sky for these mysterious clouds. The terrain just north of the community hall drops off into the Sturgeon River valley, yielding a nice flat horizon to view the NLC. See you there!

7:00 PM – 9:00 PM

Windsor Park Community League Hall
11840 87 Ave

FREE Members only event.

Presented by RASC member Jay Lavender.

Technology continues to advance the capabilities of the amateur astronomer, and as a result so has it progressed the concomitant of solar observing. We will discuss some of the methods from simple to complex for safely observing the Sun as well as the amazing variety of passband filters currently available to the amateur solar astronomer. We will then wade into a little greater detail about the Sun itself and some of the solar phenomenon and features of interest to the solar observer. If we have clear skies following our discussion, please join me for some Hydrogen-alpha and Ca II K solar observing. Hope to see you there!
