Dew at Redstone Observing Site
The image below was captured with my new Orion ST120 (a 120mm achro) on an evening where I experienced dew for the first time anywhere near Las Vegas. You’ll notice the affects of the dew on the image like the diffraction spike on Alnitak, the secondary reflection near the center, and the general fuzziness of the image. I was impressed that the ST120 could even pulled down the Horsehead under these conditions. Can’t wait to get back out to Redstone on a night with better conditions.
