This is a difficult one for me as the un-focal-reduced ED80 is a little slow, but the Ha helps. Added 35% Ha to the red channel to give it a boost, as well as using it for luminance.

North-American and Pelican nebula imaged on the night of September 2, during a few hours of nautical/astronomic twilight in Tromsø. I opted for "mono" 12nm-filter as there was still a lot blue in the Arctic autumn twilight night sky. Seeing conditions were unusually stable compared to the usual turbulent atmosphere on the coast of northern Norway. Auroral activity was also quite low.

This is my first successful attempt at astrophotography! The first night was a bust, but I learned what not to do. I'm impressed this is even possible with just an (unmodified) dSLR, a fast lens, a tripod, and special software to process a number of images! The entrance to the park area of Tuttle Creek Lake is reasonably dark and shielded from the lights of Manhattan.
I am currently using Deep Sky Stacker, a free program, to process the individual images. It is critical that the stars do not have star trails, otherwise there tends to be problems precisely registering the images so that they align perfectly. I am using the highest ISO that gathers actual data as opposed to just adding noise. This is dependent on the camera model; it seems to be ISO 1600 for the Canon T2i. Prefer a fast prime lens to a zoom lens, especially when no kind of tracking is available. I used other ISO speeds in an attempt to gather more color information.
Be sure to turn off the display when you are taking pictures. The display will add extra heat to the inside of the camera, which will needlessly add extra heat to the CMOS sensor. For a CCD based sensor the noise doubles for every 6C (10.8F) increase in temperature. I don't know if these numbers conform exactly to a CMOS based sensor, but the principle still applies. While running technical tests on the Canon T2i by shooting a series of dark pictures, I found that the sensor noticeably heats up and produces far more noise. With a comparable set of darks with the display turned on, the sensor heated up even faster and produced a corresponding amount of extra noise. As a side note, with all things being equal and with a camera that isn't temperature controlled, it is better to take astrophotographic pictures while it is cooler outside for essentially the same reason. The cooler ambient temperatures keep the CMOS sensor cooler, which keeps the amount of noise down.
I found the Magic Lantern firmware to be immensely helpful in correctly focusing my lens in live preview and also providing an intervalometer. Focusing with the live preview is helpful, but it is best to take test pictures and compare them on a laptop before you get too far. It is just too hard to tell for sure if the focus is perfect on the LCD screen of the camera. It is better to spend more time upfront than to come back and find that all of your pictures are out of focus.
In the 151 image stack there were 3 sets of images. In each set there were about 50 light frames, 20 dark frames, and 100 bias frames. The dark and bias frames help to greatly reduce the noise in the image. I used photoshop to bring out as much detail and color as possible without emphasizing the noise too much.
Comparing visible stars to the catalog in Stellarium, it appears that the faintest recognizable star is around 13.7 apparent magnitude in the 151 stacked image versus 10.8 apparent magnitude in the single non-stacked image. [Apparent Magnitude]
I initially thought that 14x times more light was being picked up in the stacked image. (2.512 ^ (13.7 - 10.8) = 14.46) because the faintest recognizable star went from 10.8 to 13.7 apparent magnitude when comparing the single image to the stacked image. I'm not 100% sure any more. I previously thought that light was being gathered in a non-linear fashion with multiple exposures. A discussion on the Deep Sky Stacker Yahoo group, claims that an additional amount of exposure worth of light isn't being gathered in the stacking process. Instead, they say stacking greatly improves the signal in the resultant image, such that the faintest recorded stars are visible above the noise. The faint stars are in all of the exposures, but they are buried in noise. And additionally Blair MacDonald mentions that "In order to be detectable in the image a single star must be about 3 standard deviations above the noise floor."
However, I'm not convinced that no additional exposure worth of light is being added during the stacking process. In an exchange with someone else he says that "… a modern SLR is truly sensitive enough to capture and digitize individual photons. The read noise is generally between 2-20 equivalent photons, so that definitely gets in the way, because the light source you're trying to measure itself has noise (Poisson distribution). But yes, you can stack almost infinitely dim sub-exposures to get a result. The extra time required goes up dramatically at some point, because the read noise accumulates, but it is possible. This is why, all things being equal, longer exposures are better. But most of the time all things are not equal."--anonymous. If cameras are that sensitive, I can see how given enough sub-exposures and stacking, a periodic photon source at a particular pixel that only shows up in every x sub-exposures could still be translated into a luminosity value above zero.
To my knowledge everyone is recommending a certain number of sub-exposures to deal with practical issues, such as noise and tracking issues over very long exposures. John Smith released a couple of papers that are useful in determining the number of sub-exposures in imaging a particular deep sky object. I have created a spread sheet based on his work that should be useful to others getting started with astrophotography. You put in an initial sub-exposure time and total exposure time and it updates two tables. One table shows different options for keeping the same SNR but adjusting the number of subs-exposures and individual exposure times. The other table shows how SNR changes by keeping the total exposure time constant, but varying the number of subs-exposures and the individual exposure times. You can find it here. You should be able to open the spreadsheet either in Open Office or Excel.
There are some options for choosing the number of sub-exposures, but there is a practical minimum exposure that is needed to record the object. The practical minimum will depend on a number of factors. Some of them include the background sky luminosity, the camera/sensor being used, and the target object's luminosity. Keep this in mind when looking at the spreadsheet.
On a related note, I went out again and took over 1,400 images of the Orion Nebula with 200 dark frames! The outing was a bit of a bust because the images were slightly out of focus and had star trails. Despite the problems, I processed them as a massive stack with sigma clipping in Deep Sky Stacker. The image was virtually noise free and it appeared that there was slightly more exposure, but not by a huge amount given the number of pictures. The faintest recognizable star may have been about .5 magnitude dimmer in the 1,400 image stack. Maybe if it had been more in focus, there would have been a more dramatic improvement?
I am working on building a barn door tracker so that I can take much longer exposures and get images that are not practically possible for me right now. Being limited to 1 to 2 seconds at 85mm is very restrictive! It will use an Arduino and a stepper motor for automated tracking. From what I have read, I should be able to get 15x as long exposures (or more) before star trails show up.
In the process of learning more about lenses and astrophotography, I found out that chromatic aberration can be particularly problematic with the use of lenses. Most photographers are more familiar with the variety known as lateral chromatic aberration. But a special kind of chromatic aberration known as longitudinal chromatic aberration (or axial color), shows up as colored fringing that completely incircles objects such as stars. This is caused by the lens being unable to focus all wave lengths of visible light at the same point. My 85mm lens is not apochromatic and thus exhibits this flaw. I have gone back and replaced the original image that I uploaded with a hand corrected version that attempts to visually minimize the color fringing. Color tends to build up perceived contrast, so I greatly reduced the saturation of color in the purplish fringes and replaced the color with a small amount of random color from the background sky. I feel that this change is a noticeable improvement over the original. If anyone has thoughts on this, I welcome their input.

I was going to have another crack at the horsehead tonight, but the high cloud was still about so I went for this instead (Alnitak doesn't like high cloud). Glad I did really - I've never got so much out of M42. Had to stop at 35 minutes because the clouds rolled in, but I had planned for 90 minutes - shame. First process, slightly hurried. I'll do it again when I get the chance.
