DSLR astrophotography untrackedWith DSLRs and standard camera lenses astrophotography is on the verge of a new epoch, where tracking is no longer mandatory. After a series of experiments we are now able to present a tried and tested workflow that guarantees great images of star fields. The basic idea of the method is actually quite simple: Shoot a lot of similar exposures at very high ISO ratings and keep the single exposures so short that no tracking is needed. In a stacking program the individual frames can then be digitally combined to create a final picture that shows faint details and is free of the noise that comes with the high ISO setting. As the sample image below shows, the results are quite astounding.
