Technical details – Canon 400D with 200mm lens, 50×30 second exposures @ ISO1600. Dark subtraction, flat field application, registration, stacking and processing in IRIS. Total exposure time 25 minutes.
Great image I did the same one Monday night for a good image stacked with only 78 seconds total exposure and I know how low this one is, so difficult to capture. If you haven't already try taking out the colour then adjsut B & C.
Very nicely resolved image. You need to keep an eye on the histogram as it appears you may have clipped the blue at least.
Colour balance could also do with some tweaking. Try a re-process bearing in mind the histogram.
Great job with the 200mm lense well done
This image would no doubt have been cropped from the original and probably resized. The amount of capture data considering could well produce this image. IMO
Something not quite right here....your sure you did not leave a zero off the focal length???
I've seen/taken enough images of omega to know even Canon L series glass doesn't give that sort of scale resolution.....
I'm sorry, it was a 200mm lens. It was on a 400D with the smaller-than-full-frame sensor so the effective focal length was 320mm. Maybe that would explain the resolution? My image is cropped to about 70%.
Peter I see what you mean. That is very strange. I have no explanation for it. I took my image in April 2007. All my filenames are labelled 200mm. You're making me feel like I'm in trouble for something. Is it possible that I took the images at the prime focus of my Celestron C8 and forgot. I can't believe that, as my PF attempts are always terribly trailed. I don't know what to say.
