NWMC Farewell
In these last few months we'll visit many of the churches for the last time, and that will be difficult. We have so much enjoyed this work and these people. It's been enriching for us to make friends all over Alberta. We've stayed in a lot of different homes, experienced wonderful hospitality, come to love the various churches and feel like they are all a family. It's been a wonderful way to finish off almost 40 years of ministry.
We had our first church on Vancouver Island in 1972, 40 years ago. However, we did take 3 years off for a "semi-retirement" in Keremeos which turned out not to be retirement at all. But God is good, and called us to ministry again with NWMC and we have felt that the work with this family of churches has been a gift from God to us.

Orion the Hunter
Rigel at the bottom is the brightest star and is the 6th brightest star in the sky. It is the left foot of Orion (think of him as facing you).
Betelguese at the top left is a massive red supergiant star nearing the end of its life. When it explodes it will even be visible during the day. It is the right shoulder of Orion and is the 8th brightest star in the sky.
Bellatrix is the other shoulder and is the 22nd brightest star.
Saiph is Orion's right foot and is a similar size and strength as Rigel but appears much fainter since its light is mostly emitted in the ultraviolet region of the spectrum which the human eye cannot see.
Meissa forms Orion's head.

Looking for Orion's belt is the easiest way to find Orion in the sky. It is most visible in January around 9 p.m. and is not visible in the summer.
Alnitak, the eastern (left) star in the belt is 100,000 time brighter than the sun and is 800 light years away. It is actually a triple star.
Alnilam is the centre star in the belt and is nearly twice as far from the sun as the other two but its luminosity makes it nearly equal in magnitude. It is 1340 light years away and is 375,000 times more luminous than the sun.
Mintaka is the westernmost star in the belt and is a double star; the two orbit each other every 5.73 days. It is 915 light years away and is 90,000 times more luminous than the sun.
The sword of Orion are multiple stars called the Orion Nebula and the Trapezium. Using binoculars you can see its clouds of stars, luminous gas and dust.

Colored Stars
So I checked out Mr. Google and discovered that stars do indeed have colors according to their temperature. Blue, blue-white and white are the hottest stars and yellow, orange and red are the coolest. Blue is about 25x hotter than red.
This picture shows some of the different colors. You may need to double-click on it to see them better.
And it is true that our eyes do not perceive the colors when we look at the night sky. The reasons vary and are somewhat technical, but a simplistic reason would be that we do not see color at night. At night our pupils dilate to let dim light in and the resulting large aperture degrades image quality. Our eyes take about half an hour at night to reach maximum sensitivity.
Taking pictures of the night sky is a challenge I'm still working on. If you photograph on an automatic setting the stars won't show. If you keep the shutter open too long, the stars will have tails because of their movement. After reading up a bit and experimenting I discovered that you have to focus manually and I increased the ISO to 1600 in these pictures.
I took these pictures at 4 a.m.! I wouldn't be doing that if it was -30! We've had such beautiful weather and it was relatively warm, although when I went back to bed it took me a long time to warm up! Even though it's dark in the evening the stars don't show up brightly until the middle of the night. Especially in town.
Now I'd like to get a beginner's book on stars so I can identify more!

Jess and Darrell made us a new sign and clock combo which we have put up in our entryway.
