Way out yonder some 40 to 50 million light years away in the constellation of Canes Venetici is a pair of interacting galaxies sometimes referred to as "The Cocoon". These two mis-shaped blobs of star stuff have already made their closest approach to each other and are now parting ways. Between them stretches a trail of stars that spans some 24,000 light years as they face each other showing off their numerous star-forming regions. But where there is life
There is death. Let's put our finger right on the pulse of a supernova.
Its in my favourite constellation! Canes Venetici... nice and a simple one. :)x

What's 10 million light years between friends? ;D

:laugh:

It's a lovely constellation full of wonderful objects such as the WHIRLPOOL GALAXY (http://en.wikipedia.org/wiki/Whirlpool_Galaxy) and the globular cluster Messier 3 (http://www.gioldasis.com/gallery/v/Clusters/Messier+3+-+Globular+Cluster.jpg.html)
-
indeed, just why its my favourite.. .also a constellation that's two stars always keeps me happy!
-
And if you can find the Plough, you can find Canes Venaciti and it's deep sky treasures.
-
yep, nice and simple really. I always have fun pointing that one out - especially to newcomers.
And Clive, seriously using the plough... doesn't Mr Jag just use his GPS telescope?
-
I'm used to star hopping and find it very satisfying. :P
-
yeah I can appreciate that... nothing like finding the object on your own.
-
My Meade ETX computer is one of the very early ones and it's not very good anyway. I think they've improved dramatically over the years.
-
yep indeed they have.
I assume yours doesn't have GPS? The newer ones do and they are pretty cool.
-
No mine doesn't have GPS. I have to get fixes on 3 stars which is easy enough to do but the system isn't good enough to get a requested object in the field of view. Just outside maybe. :laugh: This was a well-known problem with the early systems and is what prompted the MIGHTY WEASNER (http://www.weasner.com/etx/menu.html) website to start up. Have you used the GPS system? I don't think anyone at our society has one.
-
I've used one before (a few times, mostly people who have bought a telescope just cause and got a real expensive one cause they thought they had to) - was fantastic but not much better than the modern 3star alignment methods. The real solution is to get a fixed observatory though.
Oh and that looks like a useful site!

For ETX owners it's the Bible. 8-)
