Out with the old and in with the new.

Happy New Year everyone.  It is still new although I a bit am late with my greeting.
I am quite exited, I have recently upgraded my old six inch with a newer eight inch and I am very pleased with it. Once mounted, it knows exactly where to point and even talks to me. Should I want to look at Uranus, it simply whirls around and finds the exact location all by itself.

I hope no one got the wrong impression about what I am saying, it is of course a new Meade telescope with Light Switch technology. That means, it finds out exactly where it is by GPS and then finds a few stars it knows should be visible and quite quickly it is all set for me to do a bit of amateur astronomy. The only trouble is it has rained solidly ever since it arrived. Whatever happened to all those clear frosty January nights we once knew?
I bought my old six inch telescope over seventeen years ago and whilst it was a state of the art design of 1668, which is still used virtually unchanged to this day. That one was huge, being around four foot long with a massive support and counterbalance to keep it aligned. It came in a coffin sized wooden box, which took care of all the storage space in one of our built in wardrobes when not in use.

My new one is more compact being a much more modern Schmidt - Cassegrain design and whilst it has a larger optical mirror, it is much smaller in every other respect and will allow some clothes to be hung in the wardrobe as well as keeping the telescope out of the way when I am not using it. The old one required a lot of preparation and guesswork to find and view anything in the night sky, but was brilliant for looking at the moon in close detail. With my new one I hope to be able to see more deep space objects such as galaxies and so on. Obviously nothing I can afford to buy can compete with what is constantly being seen by modern professional observatories, but it is still awe inspiring to look at the sky through something a bit more powerful than a pair of binoculars.

Happy New Year everyone!


I am back after a longish Christmas break with grandchildren and great grandchildren, well ‘great grandchild’ singular.
An enjoyable time, but getting a little time to one’s self for more than a few minutes at a stretch is not always easy. Not without burning the midnight oil and anyway, much of that is taken up with chatting, TV viewing ‘essential’ Christmas TV and movies and playing the new board games distributed amongst the family’s presents, so a busy time all round with no time to blog. We also went to the local Panto, to see Little Red Riding Hood.
So here we are back in January again with the new number 2013 to signify the next twelve months on our calendar. The Earth has made one more circuit of the sun and we are, you may think, back in the same place we were last January.
 Of course in actual fact we are nowhere near the same place, having travelled somewhere in the region of a staggering 22 billion km, or if you prefer, 13.7 billion miles during 2012. 

The sun is moving along with the rest of the galaxy (the Milky Way) and all the closest group of galaxies around us, lickety-split in the direction of the constellations Hydra and Centaurus. We are not travelling towards them, they just happen to be on that side of our local sky in the direction we are moving. This mega collection of galaxies, stars and planets we belong to are falling towards an even bigger collection of stars and galaxies, somewhere beyond the Virgo cluster, sometimes known as the Great Attractor because of the powerful gravitational pull it exerts on everything around it, including us. 
Do not worry, it will be billions of years before we arrive even at the Virgo cluster. Almost certainly the Earth will have ceased to exist, long before then, let alone the ephemeral species of anthropoid we call mankind who have inhabited this planet for only a tiny fraction of time so far.

So happy New Year and may we all travel in peace for a change, after all, the universe is a big and extremely hostile place and we really ought to be working together for our continued future, not squabbling amongst ourselves over issues that become completely insignificant when set against the backdrop of the awe inspiring and unimaginably vast universe we live in.
