Hi guys. A question regarding dew & colours @ night!!!!!!!
Has anyone noticed the difference that colours make, to whether or not, things dew up?
A couple of weeks ago, (when we had good weather), I was set-up next to another member's home made, t'scope, (10" DOB). His is full gloss dark blue & my Meade is the original white. (both Sonotubes).
We were no further than 6 ft. apart, but as the night progressed, his started dewing up & the water was almost running off his tube later on. Mine remained relatively dry, & I do mean dry.
Conditions were exactly the same for both. Had to be........distance involved.
Now everybody knows that it doesn't matter what the colour of your tube is @ night, BUT, it made a difference here. We were both dumbfounded.
This is not the first time I've noticed this. It happens with Meade blue SCT's, Orion black DOB's, unbranded silver DOB,(tin tho!),etc etc.. Gotta be really bad to dew up mine.
Only talking tube here, not E/Pcs or accessories.
Has anyone an explaination?????????
