- a few weeks ago I posted about my purchase of a dept. store telescope
- (you know the kind, 200billion power, plastic everything, etc). I got
- a lot of responses and some really good information, I want to thank
- those of you who responded (more than once in some cases). Thanks!
- anyway, the scope has gone back to the store accompanied with the
- requisite complaints about the poor quality and the danger of the
- sun filter.
-
- my wife and I have since read through a couple of astronomy mags and
- a book or two, added a little cash to the pool and started down a new
- and hopefully better path. we found a local business that had a fairly
- good inventory of celestron scopes and binoculars, and other various
- brands of binoculars. the celestron binoculars that they had in stock
- were either the very small (35mm) sport type or the very large "comet
- chaser" things (>$800). they had a good stock of 7/10/16x50s in minolta,
- pentax, and a couple other brands. after a while we narrowed it down to
- two, a 10x50 minolta and a 16x50 pentax. the 16x50's were significantly
- lighter than the 10x50's surprisingly enough, but did magnify the jitter
- considerably. both appeared to have excellent optics. all reflections
- from lenses were a rich green or blue and there was no obvious deformation
- of things at the edges. since we have a large camera tripod and can easily
- attach the binoc's to the tripod, we opted for the 16x50's (although
- Mrs. Santa winced a little at the >$300 final bill :)
-
- the binocs appear to work quite well, they bring out so many stars that
- it takes me a couple of tries to locate anything in particular, I get
- lost seeing so much through them (I almost need a finderscope for the
- binoc's :).
-
- I guess my only concern is, should we have opted for the heavier 10x50's
- instead? if so, why? the 16's have a 3 degree field of view (narrow, I
- realize) compared to the 5 degree (?) of the 10's. the 16's are a little
- jittery when locating things, but once aligned on the tripod a good
- stable image is available. I'm hoping that the optics have had the attention
- they need for good 16x magnification, and tend to belive so given the
- large price jump as compared to the 10's (10's were typically in the $100
- through $200 range).
