DeviantART is counting down to its 100 millionth deviation! Join in on the fun and take a look back at some of the most noteworthy deviations we've seen along the way. The deviant who uploads the 100 millionth deviation could win a special prize, too. Hurry, we're going to hit the 100 million mark soon!

Thank you for your comments and compliment!
The reason why I didn't bother with software noise reduction on this particular resolution was that once applied, it was distracting and basically affecting the image in a negative manner. The noise reduction was acting like JPG artifacts.
Perhaps if I had shot in RAW in a larger resolution and had the on-camera noise reduction turned on, there may have been a more favourable result.
Still, I'm just starting out in this field of photography, and as time progresses (and if the clouds ever clear from Sydney!), I'll give it another shot.
I'm considering having my EOS-350D modified, but something tells me not to do it. I may just save up and purchase a second-hand 350D or a new 20Da/5D and use them for astrophotography and leave the 350D for terrestrial shooting.
Regards,

That is correct; dark frames are typically captured with either the lens cap on the lens of the camera, the body cap on the camera, or if the telescope is T-mounted to a telescope, then the telescope's lens cap on.
I believe you are correct in stating that because there is minute imperfections in rotation, the noise has been amplified. This is easily noticed in the lower half of the image whereby noise is repeating in a uniformly curved pattern.
I will be a lot more careful next time, and use a proper alignment and registration tool.
Cheers for the heads up.
