Friday 21st April 2017 - Beginner’s Night: Focal Lengths, Focal Ratios and Fields of View

8pm Friday 21st April we have our first "Beginner’s Nights", aiming to help those who are new to astronomy and would like to learn more!

Welcome to the first of our Beginner’s Nights, where we will begin to explore some of the basics of the practical side of amateur astronomy. When we describe telescopes, the first feature we usually state is its aperture, and the second is either its focal length or its focal ratio. These two figures will give us a good picture of how the telescope is likely to perform and what problems it might present. If it’s all gobbledygook to you, then you need to come along and find out what it all means as we explore the importance of focal lengths in both visual and mathematical terms, and present some “rules of thumb” that might help you decide which telescope you buy next.

Friday 14th April 2017 - Two Astronomy Video Lectures

At 8pm this Friday we will be having two different science videos for your enjoyment and education:


Cosmos: A Space Time Oddysey, Ep 5 - Deeper, Deeper, Deeper Still.


A brief supper, followed by two parallel streams of either:


Alex Filippenko: Understanding the Universe, Ep 73 - Searching for Distant Galaxies.   The finite speed of light allows observers to look back in time and see the unfolding history of the Universe.  This lecture shows how astronomers search for distant galaxies to compare with better understood, nearer galaxies.

Supper, discussions in cabin, observing.   Or:


Visual observing through the telescopes (weather permitting).


If you have a telescope and would like to know how to use it, or alternatively, would like to show it off to us, please bring it along.

Members' Night is on every Friday night commencing at 8PM sharp (doors open 7:30PM). Guests are always welcome.

Friday 7th April 2017 - Sky For The Month with Perry Vlahos

8pm Friday 7th April we have Perry Vlahos to show us what's in the sky this April!

The king of the planets, Jupiter, has returned to our skies and we're very near opposition, making it a perfect time to view this gas giant with naked eye, binoculars and telescopes. Perry Vlahos will give the "Sky for the Month" presentation this week telling you the best times to view Jove, as well as some of the highlights of this apparition. Have you seen Jupiter with only two moons or the Galilean moons all in a straight line on one side of Jupiter? Or an eclipse by a moon crossing the disk of the planet and casting a perfect black shadow on the surface of the mighty planet? You'll find out when all of this is happening and just what 'opposition' actually means, as well as looking through the MBO telescopes. Don't miss this always entertaining and educational presentation, which will also include other highlights worth viewing in the April skies.

Members' Night is on every Friday night commencing at 8PM (doors open 7:30PM) with supper following the nights activities. Guests of members are always welcome!


Please consider the neighbours and drive in and out quietly using low beam only, or better still, parking lights.

Friday 31st March 2017 - Stephanie Bernard - Looking for the First Galaxies in the Universe

8pm this Friday 31st March we have Stephanie Bernard from The University of Melbourne speaking to us about "Looking for the First Galaxies in the Universe"!

There are many fundamental, unanswered questions about the young Universe, such as: how and when did the first galaxies form? How are they connected to galaxies like our Milky Way? I’ll talk about what we know about the first stars and galaxies to form in the Universe, our search for galaxies in the first 5-10% of the Universe’s history using the dual power of the Hubble and Spitzer space telescopes, and what we hope to see in the future with the new James Webb Space Telescope.

Members' Night is on every Friday night commencing at 8PM (doors open 7:30PM). Guests of members are always welcome.


Please consider the neighbours and drive in and out quietly using low beam only, or better still, parking lights.
