The PENTAX O-GPS2 GPS Module records and embeds latitude, longitude, altitude data at the time of shooting into image files. It can now also parse information from GLONASS and Galileo systems, on top of the US standard GPS and Japanese QZSS. When mounted on the corresponding PENTAX DSLR cameras body, the O-GPS2 also offers the advanced ASTROTRACER function, which couples the unit with the camera's SR (Shake Reduction) system for the effortless tracing and photography of celestial bodies. The unit calculates the movement of stars, planets, and other bodies using the latitude obtained from the location 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. It also makes astrophotography much simpler, as it requires only a tripod and eliminates the need for an additional accessory such as an equatorial telescope.

Ricoh O-GPS2 Reviews
Works as stated
Taking photos of stars without some form if Astro tracer limits your tume exposure to about 10 seconds. More than that results in star trails. The Pentax astrotracer allows you to take exposures of up to 5 minutes without seeing star trails. Being able to take longer exposures also opens up the ability to take shots with much loser ISO and/or smaller apertures. The attached photo was a minute and a half exposure. Takes under a minute to do the precision calibration and it is ready to go. Super easy, great results. Also inserts GPS data into photo exif data.

I just started into astrophotography and this seems to work very well. I am very pleased with the photos I am able to take because of this addition to my Pentax K 70. This is an affordable way to get started with astrophotography.
