Nice clear sky this afternoon, so I got the Meade 70mm with mylar filter out, cleaned of the dust,its not been used for quite a while and had a look at the Sun, not to much activity going on only a small cluster of four small spots in a line at about the two o clock position, still nice to see them all the same. Have left the scope out and will have a go at Venus and the Moon later and see what else turns up cloud cover permitting.

I use a optical grade mylar filter, this blocks out 99.999% of the Suns light and gives a black and white image like in Robs picture and will only pick out the sunspots or eclipses, It can be bought in sheets from most astronomy outlets or as ready made up filters to fit to a telescope, for viewing the Suns surface details or prominence's you need a Hydrogen Alpha filters or a specialist solar scope, these will give a red image.
