Filters for the sun

I’ve been asked what filters I use for Solar imaging.  I just use a sheet of Baader Solar film (grade 5.0) in a homemade filter holder – made from a piece of plastic ventilation pipe!  I normally use just this filter.  It is suitable for visual observing but I have a personal rule of never looking at the Sun with my eyes, safe filters or not!  One silly mistake and the Sun will blind you.  I only ever use a camera.

I do have a green filter but have found that I get just as good an image without it.

Summer Holiday Sun!!

Today we had clear blue skies and quite decent seeing for once.  Quite a string of AR's across the southern hemisphere – hopefully some of them will develop over the next few days.

I had to wait all day for a clear patch and then it was only enough for 52 frames!  Stacked 43 of them for this image.  An interesting new big spot has appeared - upper left!
