Comparison on C5
I'm just wondering what is the difference between a standard C5 astro scope
OTA and that of their spotting scope version? Are they exactly the same? As far as I know, they are the same. More modern versions are apt to have "better" coatings, but that's about it. The coatings are no less valuable in a spotting scope, which is also used in low-light. Robert B NY |
