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!
Just want to share an image of M8, I took recently.
This is my new attempt to improve data on my images. I have taken on two different nights the data for H-a and RGB. The H-a image was taken on 16th May 2009 using my Canon 300D (mod) and Baader Ha filter. A total of 16 images with 300 seconds exposure are the process with IRIS. Only R channel data is saved.
On 4th June 2009, I used my Canon 350D unmod camera to take the RGB data. The reason behind this is that my 300D has been mod, but I don't have IR blocking filter. So, using unmod camera, I hope to get a better star size and colour. Because of the Moon, the exposure is only 60sec long with a total of 30 images.
Both data were combined in PS. Both photos taken using Mak-Newt 190 on EQ6 GOTO mount. Autoguided with guidedog and autoexposure with DSLR control.

Thanks for the nice comment. I'm sorry I missed out the mount info. I am using EQ6 goto mount. I am using a cheap 80mm achromat refractor of 600mm for guiding. The scope is rated at 1000mm @ F5.1. The image has been cropped and reduced 50% for smaller file size.
