- In 1986, in preparation for a cruise off the Brazilian coast,
- nominally to see comet Halley, I bought 7 X 50 K-Mart Focal brand
- binoculars for about $50. These rubber encased binoculars gave very
- satisfactory performance until recently. Now they are decollimated, so
- that star images are double. My visual accomodation can fuse bright
- images, in the daytime.
-
- I don't know what the cost is in eyestrain of the decollimated state
- of the glasses, but I want to replace them with a properly collimated
- pair. The question is will a more expensive set be less prone to
- accidental decollimation than a cheap set? The old ones have cost me
- about $8 a year!
-
- Incidentally, the views of the comet were not especially better than I
- had in Ohio, but oh, that Southern Hemisphere sky and the Magellanic
- Clouds!!
