I was very pleasantly surprised to get this from only 6 subs as the clouds rolled in as per usual!   Orion, the horsehead and the flame by John Phelan, on FlickrՕFlickr

If your using the Skywatcher Star Adventurer, would you have gotten the same results if you shot one long exposure and used the tracking mechanism. Who's mom kidding, I don't see any electricity in there.

Thanks, Tim Thank you. For now I have only managed a maximum of two minute single exposures without star trailing at 200mm, if I can get to three minute exposures I'll be delighted, that will be down to exact polar alignment and perfect balancing. To get ten minute exposures you are getting into serious money for a good German equatorial mount! ՕFlickr

I looked at your "Heart and Soul Nebulae", another great picture by the way, and saw that you used the Skywatcher Tracker and a total of 71 shots, Is it save for me to assume that even using the Tracker you will still need to take a series of "short" shots and stack them as opposed to one "long" single exposure. Who's mom kidding, I don't see any electricity in there.

The others were calibration frames. Stacking shots improves the signal to noise ratio so you end up with a less noisy image, corrects vignetting etc. Before I really got into this I bought a book called Making every photon count, I highly recommend it, it explains in laymans terms everything you need to know, there are also some great forums out there like stargazerslounge and cloudy nights that have a wealth of knowledge on them as does here, but the are specialized to astro stuff ՕFlickr
