  1. Excellent responses all! Thanks guys. While I'll acquire a barlow, I may only use it as a last resort (after experimentation).
  2. Generally speaking is there any advantage in using a 10mm focal length eyepiece over using a 2X barlow with a 20mm EP? I'd like a wide angle EP, but will the barlow destroy that WA view (or even create the WA view for a narrow angle EP)?
  3. Nightfisher, When you say "way behind" are you suggesting not as good, and if so in what regard do they suffer? In other words what are the primary acceptance criteria for a barlow, and which do the "cheapies" lack? Thanks
  4. It works for me, but I had to switch languages.
  5. Thanks guys. I would have gone out and tested it myself, but we are so clouded over right now it was not worth the effort of getting it all set... And I knew you guys would come through for me!
  6. Please excuse the newbie question, but if I should insert a 2X Barlow in my light path (assume I'm going to use the same eyepiece I was already using - say a 10mm for simplicity's sake) will I need to be extending the focus (backing the eyepiece out) or compressing it (moving it in) from where that 10mm eyepiece was previously focused?
  7. This seems like a GREAT thread, and I have just started reading it!! I have two scopes (1) Celestron 6" AVX Refractor, and (2) Orion ED80T CF, so my EP kit will range from 6 to about 25 (along with a 2X Barlow) if I understand correctly. I bought a set of Celestron EPs recently and envelop this range so I think I am good to go. Thanks Warthog!
  8. I'm Tom, a newbie both on this forum as well as in astronomy. I'm a systems engineer and consultant to NASA/GSFC and DARPA and space-based hardware suppliers. My specialty is Reliability Engineering and deal primarily with spacecraft buses (rather than instruments) including the Compton Gamma Ray Observatory (GRO), the Extreme Ultra-Violet Explorer (EUVE), the Upper Atmosphere Research Satellite (UARS), the Hubble Space Telescope (HST), the SOlar Dynamics Observatory (SDO), and most recently the Joint Polar Satellite System (JPSS). I have yet to buy a telescope and will rely on the NASA/GSFC Astronomy Clubs resources until I can figure out what I want to buy and use. But first I have a lot to learn about the celestial environment and the way we Earthlings find things with in it. I'll be anxious to see what you all have to say and show.
  9. I am glad to find this forum. As a raw beginner in astronomy, but having supported NASA for over 30 years, I'd say I am playing catch-up for this characteristic to NASA functions. My role at NASA has long been as a spacecraft bus designer and analyst (including HST, GRO, SDO, et al), and very rarely involved with the instrument and scientific investigative side of things. I've always had an interest in astronomy and also photography, but up until now the photography alone won out in getting the attention. Now I'm anxious to explore a new photographic endeavor and enjoy viewing the universe at the same time. I also notice that the Beginners Forums here are multiples - that is better than I have ever seen on any other forum (of any kind). I'm looking forward to learning from you all. Tom
