Review on Astromania Flexible Dew Shield For Telescope Front Outer Diameter From 100-123Mm Diameter - Keep Dew Away And Gives You Clear Observing For The Entire Night by Rob Allen
Great dew shield. Measure the outside diameter of of the front of your scope, not the aperture.
I ordered the shield for a 123mm to 142mm diameter scope for my NexStar 127 SLT going by the aperture of 127mm. Wrong! It was too small. The outside diameter of the scope is 144mm. I ordered the 147mm to 167mm and it fits perfectly. In retrospect, if I had read the description more carefully, I would have seen that the dew shields are sized for the front Outside Diameter of the scope. This is a great dew shield. It fits well, stays in place, blocks extraneous light and prevented the formation of dew on the front plate of my scope when I was using it tonight.
- 17.1 x 7.1 x 0.12 inches
- The shield does not come with a storage case, making it difficult to transport
