ahh the old varying index of refraction with temperature trick. I would have never thought such things could have a big affect on the image quality. Those mirrors must be extremely well shaped.
Bird: Your telescope looks brillant, I'm very impressed! How long did it take to build? Have you measured the hotside of the Peltiers? It looks like getting the heat out of the Al plate on the hotside will be a restriction in the heat flows. Peltiers can be great coolers but you HAVE to get the heat away from them VERY efficiently. This is where all those cheap powered eskies fall down. In a good system the hotside should be 5 to 10 C above ambient to get the most out of the peltiers.
Iceman:
I found this forum from a magazine, Sky & Telescope I think it was called. I tried to google for an Aussie astromony forum but never found The forum.
Now I'll tell you want sort of telescope I have but you have to promise not to laugh. My telescope, purchased at great expense, cost me a whopping $76 for a 76mm reflector from **** Smiths. (you promised!) Hey for $76 you cant go too far wrong and when I was able to see Saturns rings it blew me away, by far exceeding my expectations of the telescope. I have however seen speed boats that are more stable. Once I have read these forums a little more and I have a better idea of what I want I will be asking some questions about what to get as my first real telescope.
Cheers
Brett
