Eyes on the Sky: Two double stars for moonlit nights

www.eyesonthesky.com With a full moon approaching, turn your telescope towards two different double stars instead of fainter deep sky objects. Eta Cassiopeiae and Gamma Delphini are worthwhile objects to seek out and see what colors you can see in these autumn doubles. See what's up in the night sky every week with "Eyes on the Sky" videos, astronomy made easy.

Sir plz can u Make a Video about how to clean the dust that has been collected on the primary mirror of a telescope plz ??

[@julianpetit4180]

Compressed air is your friend sir

[@Eyesonthesky]

First, consider not doing anything. Even very bad looking dusty mirrors still perform very well compared to scratched ones. Short of that, remove the mirror from the cell. Soak in water with a TINY bit of detergent for about an hour. Then rinse with lots and lots and lots of water. Do not touch / scrub / wipe the surface at all! Finish by rinsing it with distilled water. Then leave the mirror on it's side to drain excess water droplets until it dries, and return it to the tube. It may not appear "pristine" but again, a somewhat dull looking mirror is still better than one with lots of micro-scratches from rubbing or wiping.
