Since then, amateur astrophotography has considerably evolved. First with the webcam revolution : with those cheap small cameras, you can film planets at a high rate to freeze turbulence, select the best among tens or hundreds of frames of the film and then composit them to create a high resolution image. Finished with silver halide photographs of planets, most of them blurred by turbulence, ending their carrer in the dust bin. Farewell to completely wasted 24 x 36 films...
Then appeared DSLR's cameras, some of them specially modified for astronomy. With their huge chips, they allow taking wide field images, even if they still suffer the flaws of non-cooled devices.
