You'll have to deal with reciprocity failure, otherwise known as the Schwarzschild effect. You'll also be limited to lower sensitivities (ISO) with most readily available film than with most digital cameras. With film you won't have any hot pixels, but faster film is grainier than slower film. Unless you're willing to invest in a fairly expensive sidereal ...


No, digital will be still better than film, because of its higher sensitivity and ease of use. All serious astronomy work moved to digital even before amateur dslr cameras appeared. Dead or hot pixels are usually not a problem because they can be eliminated during the processing - unlike regular photography, astrophotography is almost always a result of ...


The problem with film is that it's sensitivity reduces with the reduction of power of light source. This means that if you need exposure time x to get a satisfactory photograph, the light source with small power (i.e., magnitudes dimmer than day sky) y, you will need much more than N*x exposure time if you decide to photograph the same light source with ...
