How many exposures Robert?

Please can you post a single exposure image version.


44 images used to make that star trail picture at 40second intervals which according to my calculations is 29.3 minutes duration! Not bad for a guess...

Here we go, I have done a little more processing on this one just to pull out a bit more detail, the processing of the star trail batch was slanted towards uniformity for the batch but this one is aimed to get the best (I can) from a specific image.

Same exposure details as the star trails image above.



This is a 100% crop from the same image (one image pixel to one screen pixel), centred on Polaris, same processing.
