2 weeks ago, I ordered
Baader Astro Solar Film from Baader Planetarium. My main purpose was to observe Venus transit on 5-6th June 2012. It arrived as a A4 size sheet of solar filter placed in a hard envelope. I built the filter as explained
here but the resulting filter looked rudimentary because of my lack of hand skill. Next morning i could not wait to take trial shots with the filter and found out that although the filter does not look promising, the image quality was nice. For example, following picture was taken on 11th February 2012 morning and you can see 2 close sunspot sharing same sunspot number.

Sony DSC-H1, fl:432mm (35mm equivalent), f/5.6, 1/500s, ISO 64, ND5 Solar filter |
The sunspots seen on the picture are smaller than Venus' size during transit so it seems that i can take Venus transit shots with this filter if weather permits. This year Sun is quite active so i wish i can take better sunspot shots this year.
