CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!
I have been modified my 350D camera long time ago by replace the internal original low pass filter with Baader UV/IR cut filter. Since the modification, no chance for me to test it out due to weather condition.
On Saturday night of Sunday morning, the sky opened for about 30 minutes. However, only not more than 10 minutes to take some test shot. This is because of equipment setup time and focusing time consumed.
Below is the test shot image. I found it is very promising to take nebula image by replacement of the DSLR filter. I added a light pollution filter to reduce artificial light reflection from the atmosphere.

Hi very nice! You managed to bag 2 at one go!......... From what I have experienced, 350D can go up to 5 minutes exposure b4 noise becomes an issue.......
