Top is the most recent, middle was imaged in May, and bottom was my 1st ever DSO photo in Feb 2012. Only thing that's changed is that I now shoot with a Canon 60Da instead of 5Dmii, I also guide via PHD (and since I started astrophotography I've done a fair whack of research and spent time outside)
Interesting, finally after some 6 months of ownership I have finally got an image out of the C8, not entirely its fault(bad workman always blames his tools etc) but the weather here has been really bad or I've had work commitments.
The framing is completely off on this but I just wanted some exposures in the bag and to test the polar realignment feature of the new V3.32 synscan handset, seems to have worked ok in this instance.
Not too happy with the image quality, think I may have been spoilt with the L series lenses Ive used in the past, could be that collimation has something to do with it too, vignettes and CA's at the extremes so cropped in a little. Still testing.. Worthy of note is that I didnt use any LP filter with this image as I figured the area in the sky I was focusing on was so small there would be less noticeable LP than in larger areas..

Celestron C11 Edge HD, ASI290MM, enlarged 15 percent in Photoshop in post processing. Best is to look at the full size image here in order not to miss the fine detail.
Canon 5D3 with Celestron CGEM 1100HD and 0.7x reducer. Stack of 21 images at ISO 800 and at 10 minutes exposure, each with dark frame. Manual Guiding with Celestron off-axis guider and Orion's 12.5mm illuminated reticle eye piece.
The very dim surface brightness, haze and the 5D3 IR filter all combined to make it very difficult to get the H II region without noise. Still, the seeing was the best yet so the stars are fairly pin-point. The 0.7x reducer is both very good and very heavy (big chuck on glass!). Very little coma in the corners, some small amount of chromatic abberation (but that is correctable in software).
The cocoon is is about 12 arc-min across (about 1/3 size of the moon) and is both a reflective and emissive region being driven by the young star (100k years) in the middle. The darker blotches surrounding it (areas of fewer stars) are the result of dust, part of a dark lane that surrounds the nebula.
Celestron CGEM 1100HD, Canon 5D3 using EF 70-200mm/f2.8L IS II set at 200mm (scope mounted)at ISO 400 and f2.8.
25 images were taken at 5 minutes per with dark frames for each. Images were stacked using DeepSkyStacker (which found over 65,000 stars in each image!) and then post-processed in GIMP. With 25 images that reduces noise by a factor of five (~2 stops or equivelent ISO of around 100 starting with 400). At 200 mm the area covered was considerably more than the Nebula so about 1/4th of the image was used. Even at that, the lens did a terrific job in capturing the detail. Additional noise reduction in the darker areas was achieved by converting the final image from RGB to YUV and then Gaussian filtering the U/V channels then converting back to RGB.
You can see why they call it "The North America Nebula" - top-center down to center looks like the North American Continent (gulf of mexico and all!). To it's right is the Pelican Nebula (IC 5070).
I used the telescope to do tracking while the scope-mounted camera and lens did the photographing. I had brought along my Canon 60A so I could take this without the IR filter of the 5D3 but forgot the adapter to connect the timer into the 60A (the two cameras use different plugs... thanks Canon!). The reason the IR filter is important is because the reds are H II regions and they emit close to IR frequencies (656 nm) - the 5D3 IR filter reduces them by a factor of 6! The 60A is specially designed to not reduce these reds (by much anyway).

-60mins total exposure; 4x100s 4x300s 4x500s sub exposures. Could use at least 12 or more 300s exposures to bring out greater detail in the nebula. Highly cropped, very slight histogram stretch (Photo has been replaced).
Definitely my best work to date. Really happy with the results, light-polluted Honolulu or not! I did get some 900 second subs too, but didn't include them because of severe vignetting from the target setting over the city. But man those 900s subs were really pretty! More detail in one of those subs than this whole stack here. Need to start taking flats too...

This is my Celstron C90 MAK on the Celestron Tripod, with an Olympus TG-2 digital camera being held by the Celestron holder. I wanted to experiment with astro-photography and this was an inexpensive (relatively) way to get in. The telescope, tripod, and camera holder were about $300 all in. Seems to do a pretty good job right off the bat, however I expect things to improve as I work out the details in the set-up.
