The Messier 10 minute challenge was done as an experiment so that I could see what quality of image could be obtained using modest scopes (a 10 inch reflector was the largest I used), with a series of relatively short exposures but from a first rate observing site. I had a lot of fun and I learned a good deal about the techniques to use with the different kinds of objects. Of course I would be the first to admit that the "astronomical significance" of the work has not been massive!
One important lesson I did learn was the "law of diminishing returns" operates much the same with astronomical imaging as it does with many other facets of human activity. A twenty minute image was not twice as satisfying to create as a ten minute image nor was it twice as good. In fact in many cases there was little to chose between them so, even with hindsight, I'm glad I didn't go for the multi-hour exposures favoured by some colleagues.
I created an internet forum to showcase these images and I have pleasantly surprised by how many "hits" the site receives.
