New solar filter

[Paulb3098]

Made myself a larger solar filter, baader film, two pieces of 3mm card and a 12" embroidery ring from hobbie craft. Sharp knife and lots of masking tape. Last effort was only 2" so the large aperture makes a real difference to the quality when viewing, took a picture with my phone will post some web cam shots later:hello2:
