Re: [APML] Canon D20a pictures

Hi,

As I know, 20Da has less noise than 20D.  
Its H-alpha response is better than the original 20D, but still about 50% less 
than a modified 20D.

If I'm rich enough, I will buy a 20Da and remove its IR-blocking filter.
Then this is probably the best astro DSLR you can get.

Cheers,

Wei-Hao
