That's pretty cool, I was thinking of trying the same thing with my A300/2.8 and 1.7AF TC on the K5 and possibly testing the astro tracking on the GPS unit, light pollution here isn't great for night viewing though. -- Rob Studdert (Digital Image Studio) Tel: +61-418-166-870 UTC +10 Hours Gmail, eBay, Skype, Twitter, Facebook, Picasa: distudio -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Saturn's bright, you don't need tracking and light pollution shouldn't be a big problem. I shot at ISO 100, f/8 set on lens (so f/11 effective), 1/4 second. I don't think you want to go much longer than that without tracking, but there's obviously plenty of room to speed up ISO and aperture from what I shot. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

OK, that suits my set-up fine, the A300/2.8 + AF1.7TC combo work best close to wide open so my shutter speed even at ISO 80 should be near or faster than 1/4 sec, thanks for the info.
