Here’s the reason I’ m always banging on the drum when I talk to the group about safety when viewing the sun.
Just to show you how quickly and easily things can go very badly wrong with solar observing, I set my scope up the other day to look at the sun and couldn’t understand why I was seeing nothing at first, then I started getting some images
When I removed my Hydrogen Alpha filter later , I realised that I had actually left the dust cap on, hence why I was not seeing anything. As you can see, the sun sorted that out for me very quickly!
And I’m supposed to know what I’m doing !!!!
