Re: [APML] Hyper times...

Jim and Bobby,

Thanks for the info, I will be putting a list together from the archives
shortly and I will give the URL at that time...  I used to do 2415 and no
other, but alas, I think I am going to sell off my Hyper Chamber and go
CCD...  I got quite carried away with Hypering back 10 years ago, and ended
up with a full sized welding cylinder of forming gas...  Used most of it
too...  :)  I live in Oregon and it rains a LOT here, so 95% of the time I
was testing...  I still have the Densitometers, Vac pumps, and my homebrew
Hyper chamber...  See December 1989 S&T for a photo of it.  It's a bit
larger than the Lumacon version, in fact you can put 3 or 4 of the 300
chambers inside this one...  :)

If you do look up the picture the gauge is 2 inch diameter...  Anyway, I
will be starting over again, and am now doing all the homework to catch up
and get going under CCD and not film this time.  But I will use the chamber
one or two more times before selling it off...

Thanks to both of you for the information, and it's good to see Hypering is
not dead!
