ALL Aerosols are TOTALLY banned on or near the observing field at all Snake Valley Astronomy Camps.
Has been that way for a few years now.
This was brought about because some Aerogard was carried by a breeze onto an attendee's Takahashi telescope. The chemicals had eaten into the optics coating.
Shipped off to Japan and $5000 later the scope was repaired!
It is a good idea NOT to use aerosols ANYWHERE NEAR your gear.
Roll-on obviously can be used near your gear. Just be careful around eyes and fingers.
