Here is my latest. Mid Dec I added to data I collected in Aug and only now processed them.

This one is 4:25 hours and needs more luminance and some more red or Ha.
One point I may make generally speaking now- with DSLR images, often the images are very "short" exposures. By that I mean less than a hour.
Almost any object will look great with enough exposure. A rough rule of thumb is a minimum of 2 hours total.
DSLRs have the ISO setting so you can adjust the sensitivity whereas CCD cameras that gain is set by the manufacturer. This means you can artificially crank up the camera and it can invite you to take less exposure time than is really required.
With DSLRs one rule of thumb is to set your sub-exposure time to below where the sky glow becomes intrusive. If you live in a light polluted area (most would) then an light pollution filter helps. You can even do Ha with a DSLR although it requires a 2 inch screw on type (more expensive).
ISO 800 is often quoted as a good sensitivity. I always used 1600 or 3200.
Another thing that might help with DSLR imaging and this may be a more advanced technique. To take a short exposure for the stars only and longer for the main object. Photoshop allows you to remove the stars from one image and blend in the stars from another. DSLR images often have white stars with no colour. This is the most obvious difference between DSLR and CCD images. The CCD camera can expose longer without spilling over than most DSLRs (although the Caon 5D has lower noise and higher almost everything than an STL11).
The new breed DSLRs are now 14 bit and extremely low noise (Canon's at least - not sure about the Nikon's). The gap is narrowing especially now CCD cameras have a range of one shot colour cameras available and seem to be increasing in popularity. Apogee Ascent series are a lot cheaper and closer in price to DSLR top range and Sbig is bringing out a 10.5mp CCD camera shortly that is supposed to be fairly "cheap".
For autoguiding there are heaps of options now. The Orion Starshoot, the Meade DSI, the Celestron Neximage, The ToUcam (modified) and a hot one is the QHY 1.3mp CMOS chipped autoguiding camera which is US$245. That's a real bargain and use it with PHD guiding software (free). It may or may not need a Shoestring Astronomy adapter for your mount depending on what you are using.
Cheers,
Greg.
