Standard warning for random readers:  it is very dangerous to look directly at the sun, especially through binoculars or telescope – permanent blindness is the likely outcome.  NEVER do this unless you have a solar filter or solar scope bought from an approved astronomy dealer, and have the advice of experienced astronomers.

Safety first:  Take out the Baader filter; examine it indoors; examine it outdoors; put on 5 inch telescope and look at the ground; aim at sky and look for holes; aim at sun and look with bad eye; finally look with good eye.

Through the skeins of cirrus the disc of the sun showed several active areas of spots, plus one on the limb.  I watched peacefully for a while, swapping eyepieces and Barlow in and out.  Eventually I tried to document what I saw by snapping down the 9mm eyepiece with my little hand-held Canon Powershot.  One or two were reasonable; but don’t show the details of the monochrome disc floating in the eyepiece.

  1. Nice photo! 🙂 I’ve taken photos of the Moon with a digital camera held up to the eyepiece… if I got a filter, I’m sure I could do the same with the Sun… hmmmmmm… now you’ve got me thinking…

    • I find it more difficult to get a good image of sunspots than of the Moon, with this primitive technique. Of course a ‘proper’ filter is very pricey -that’s why I used the Baader solar film, but as you can probably tell I feel a little nervous about it as the film looks so fine and flimsy (though obviously very effective).

      • I don’t know what my old eyepiece filter was made of – it came with the telescope when I was 13 so it was quite a number of moons ago now LOL It was a “proper” filter though… don’t think it was welder’s glass! LOL
