Hi All, Just a short note to let anyone that might be interested in making the trip to Australia to observe from 17 May 2009 to 29 May 2009 that the Ozsky 2009...
... This was the southern sky experience I went on this past March, and I highly recommend it, having no connection to it except as a happy "customer". Anne...
... I joined Ann and her gang along with Dave Kriege of Obsession in the Spring of 2005 and had a wonderful time. Imagine several Obsession dobs of 18', 20" ...
Hi All, I have a stock Orion 12" newt/dobs with the mirror well collimated. I was wondering what magnification ep would be at the max range of this scope.I...
Carol, It attaches to the focuser and lets you focus without touching scope. It has a fast and fine focus setting for fine tuning image views at high power....
Under most circumstances, due to the atmoshere, about a 5mm would be it. That's a little over 300x. Doug ... -- A good day to Golf is a better day to Fish ...
Thanks to everyone for their valuable suggestions. Lunsford, thanks and if I go with 90mm refractor, what will I be able to view. Will it limit me to...
... I'm coming to this discussion late, but I would _not_ recommend a 90mm refractor as a beginner's instrument. The aperture is too small to resolve much...

... I'll strongly disagree with that! The 4.5" (114mm) Orion Starblast and Skyquest are good quality scopes on solid Dob mounts. When collimated, both will...
Does anyone have experience viewing with a home made solar filter made from Baader AstroSolar safety film? I'm looking for a way to make an inexpensive solar...
Why would they say that? F/5 is just fine, lower can be a bit tough for average eyepieces, but otherwise lower than f/5 are fine also. Doug ... -- A good day...
