Here is the place to talk about all those equipment(Telescope, Mounts, Eyepieces, etc...) you have. Not sure which scope/eyepiece is best for you? Trash it out here!
Apparently one of the functions of Pentax O-GPS1 GPS Unit is it can act as:
ASTROTRACER for effortless astronomical photography
When mounted on the PENTAX K-5 or K-r camera body, the O-GPS1 also offers the advanced ASTROTRACER function,** which couples the unit with the camera’s SR (Shake Reduction) system for the effortless tracing and photographing of celestial bodies. The unit calculates the movement of stars, planets, and other bodies using the latitude obtained from GPS data and the camera’s alignment data (horizontal and vertical inclinations and aspect) obtained from its magnetic and acceleration sensors, then shifts the camera’s image sensor in synchronization with the movement of the objects.*** As the result, stars and other bodies are captured as solid points rather than blurry streaks, even during extended exposures. It also makes astronomical photography much simpler, as it requires only a tripod and eliminates the need for an additional accessory such as an equatorial telescope.
** This function is available only when the O-GPS1 is mounted on a PENTAX digital SLR camera body equipped with a magnet-driven SR system.
*** The duration of ASTROTRACER operation may vary depending on photographic conditions.
If exposures of 4 to 5 minutes are possible mounted on a camera tripod then what are we doing with EQ mount. Makes a greater grab and go imager.
Anybody owns a Pentax DSLR and got good contact with the Pentax distributor.
Peter Lee (tan14.com) sells the GPS accessory. It's about S$300.
Sometimes I am tempted to get a used K-r and the GPS accessory and see how it works out.. but I unloaded all my Pentax gear a year ago (almost exactly).
Kindly ensure the below setting are set:
slow shutter speed noise reduction (off)
high ISO NR (off)
High ISO noise reduction starting sensitivity level (ISO 3200)
Done. =)
