But I think you're wrong in assuming there is a physical process behind most of them. You really need to use a good planetarium programme to check the distances to the stars. You'll see they are often hundreds of lightyears apart. Attached is a chart of a string of stars in Cygnus I found very conspicuous and enjoyable in my 8,5x44 a while ago. I've labelled the stars with their distance per the Hipparcos catalogue. -------------------- Mark Leica 8x20; Vixen 8x42; Swift 8.5x44, 10x50 and 20x80; TS 7x50; Orion 15x63 WO Megrez II 80 FD + Baader 90° T2 Amici Post Extras       Entire thread Subject Posted by Posted on Star lines, curves, and spirals refractory 08/09/06 06:32 PM Re: Star lines, curves, and spirals EdZ   08/09/06 07:15 PM Re: Star lines, curves, and spirals rushintuit   08/10/06 12:48 AM Re: Star lines, curves, and spirals Glassthrower   08/09/06 09:01 PM Re: Star lines, curves, and spirals refractory   08/10/06 12:48 AM Re: Star lines, curves, and spirals EdZ   08/10/06 07:39 AM Re: Star lines, curves, and spirals Art Fritzson   08/10/06 10:42 AM Re: Star lines, curves, and spirals Mark9473   08/10/06 11:38 AM Re: Star lines, curves, and spirals refractory   08/10/06 02:01 PM Re: Star lines, curves, and spirals Mark9473   08/10/06 04:02 PM Re: Star lines, curves, and spirals KennyJ   08/10/06 04:21 PM Re: Star lines, curves, and spirals refractory   08/10/06 09:39 PM Re: Star lines, curves, and spirals Art Fritzson   08/10/06 02:50 PM Extra information 9 registered and 28 anonymous users are browsing this forum.
