- OK, it was an impulse purchase: I bought a Pentax 10x50 pair of
- binoculars. I was a virgin astronomer--totally novice. One
- night this past weekend, I went outside and lay on the ground
- and, with the 10x50 Pentax binocs, LOOKED UP! Geeeese! Lots MORE
- stars than I could see with the naked eye; but they jumped all over.
- I couldn't really hold the binocs still enough, even using a technique
- for handholding that I learned from sci.astro--move hands to eyepieces
- and rest against your face. No moon at that time, so I was content
- to look at jumping stars AND what I think was a satellite as it passed
- over. That was neat... I do have some questions.
-
- Is the Pentax a good binoc to use? It cost $150 at local discout store.
- The specs on it say that it has a 6.5 degree field of view; is that
- suitable?
- The specs say it has a "relative brightness" of 25; what IS "relative
- brightness"? Is "25" appropriate?
- In their literature they have an 8xsomething that has a relative
- brightness of 50? Is that better for astronomy viewing?
-
- At this point, I probably am going to return the 10x50's for the 8xsomethings
- so I can hold it still, and have a clear image. Advice would be appreciated.
-
- BTW, re my "first experience" -- it didn't hurt, I do want to do it
- again, but I see I need to learn somethings to make it better, and
- I hope you all will still respect me...
