Venus Black Drop Effect

Blogged by Aurélie Le Fort-Beunink on June 12, 2012 and tagged with Sample Images, Sun, Venus Transit.

I use an Astrophysics 130mm refractor with an F4.5 field flattener on a Losmandy G-11 mount. My solar filter was Baader Planetarium Astro Solar safety film (visual). For the closeup shots, I used a Powermate 2.5x barlow in front of the camera. The camera is a DMK 41AU02.AS. For image processing, I first used AVI Splitter to trim 400-500 frames or so out of the master shot. Next, I stacked those frames using Autostakkert2. For the final process, I used Photoshop CS2 to adjust the levels and sharpen the picture using unsharp mask.
