it is way too big

pheew, ok I am mixing up several techniques, therefore I understand it can be confusing. let's recap 1) the 10mm 2.8 would be the nicest solution for a simple single shot image. I agree 2) 24mm 1.4 would give without any doubt much more light (it's true that I can expose for only 15 seconds...

hmm ok, it is still a viable solution...many people use it for large night landscapes in place of using a torch: knowing this, would you still go for the 10mm?

well I was implying a double stacked exposure....which is pretty normal in most of the cases (not all, especially if you use a torch, but most)

well for stars photo ultra fast can be a big difference, no?

if you had to choose a lens for stars photography, what would you go for, a 10mm 2.8 or a 24mm 1.4 (and then stitch more photos)?

good observation :)

don't worry, my reasoning was slightly different, but not sure if it was correct. As you said I was more worried about the more distant stars, which if missing could make the frame a little bit emptier. I'd like to shoot something like this...

well a 10mm covers a huge amount of area and the number of pixels on the sensor is fixed...that means that small stars could get lost (but it helps for the trails ;))

the question is if on a 16mp I will loose too much detail (stars not visibile anymore)

Thank you very much for the answer. How come you say the pace was not simple? Another question, with 1.5x crop factor and a 16mp sensor, what focal length would you suggest to use?

it seems to be related to the wide angle distortion....

oh, wow, I did not know about this rule and I am also not sure if I understand it. What is the physical explanation of it? (never mind this question, I am already reading this: http://photo.stackexchange.com/questions/30263/what-is-the-rule-of-600-in-astrophotography) Anyway now I am looking...

Hi, my first attempt of night shots: https://plus.google.com/u/0/photos/105257085260231047119/albums/5919896921865608241 There is something I am missing there, so I am looking for advices. First: this is the INTECH Science Centre - Planetarium, as I suspected the quality of the sky...

I am waiting october to go, hoping it won't be too cold, since the sunset will be visible then.
