Mod Sony DSLR

I use a Sony A200 DSLR for astrophotography and had to be content for a while with its limitations. Naturally I wanted to be able to take images of nebulas with that nice red glow. Obviously this meant either buying a dedicated astrocam or modify the camera. First option was too expensive which leaves me the second one. But alas, most DSLR's are Canons. And I couldn't find any articles on moding a Sony. So I found myself on my own in moding this camera. I did a bit of research and I concluded that the Sony A200 sensor is similar to a Canon 350D and so I ordered the appropriate Baader Planetarium filter.

To make the story short I got the sensor off and replaced the original filter with the Baader filter with fantastic results IMO.

Here is a before and after shot and some photos of the camera. The image of Orion in the before shot is about 3 minutes, no darks, no flats, a bit overprocessed to bring out the nebulosity. The after shot is about 1 minute, no darks, no flats. Processed in DSS.
