Pentax 105SDP (Apo telescope, 670mm fl, f/6.38) with a 2x power mate giving 1340mm f/12. Unguided, 3 second exposure with an ATIK 383L but downsized to 800x600 from 8MP. Used a Baader neodymium filter:
Usually planets are too bright for the 383 as it's designed for longer exposures. This was so early in in the phase at it didn't saturate.
Jupiter, unguided using same scope & 2x with just an ATIK Titan (650x450 resolution) for high frame rate (~17fps, 1/10,000 sec exp) giving ~700 frames stacked in registax 5.1. Again, a neodymium filter. Cropped at native res:
