This is the coolest thing i have ever seen - GPS for Pentax DSLRs

Pentax to announce a new GPS unit for DSLR cameras (O-GPS1) | Photo Rumors
and
Re: Pentax adds GPS unit with Astrotracer: Pentax SLR Talk Forum: Digital Photography Review

OK, at first glance it looks like your standard GPS unit.

BUT:
Astrotracer for astrophotography
The O-GPS1offers the advanced PENTAX original Astrotracer function,* which works with the PENTAX Shake Reduction (SR) system on select cameras for tracking and photographing 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, the unit shifts the camera’s image sensor in synchronization with the movement of the object(s). As a result, stars and other bodies are captured as solid points rather than blurry streaks, even during extended exposures. The unit also simplifies astrophotography by requiring only a tripod and eliminating the need for additional accessories 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.



SO COOL

I have never done any astrophotography, but that does sound really cool.

Agreed. It is pretty cool, probably wouldn't use it myself but interesting concept.

Astrotracer is interesting - I wonder how well it would work for longer lenses to capture those distant galaxies and nebulae.

Or even on the nearer side of thing, the moon shots.

The moon is so bright, you really don't need super long exposures like you do with deep sky objects.

autotracer would be cool, would that be where it shifts the sensor for you to achieve perfect panning shots of racing cars everytime? Sorry couldn't resist.

True, but i'd think anywhere under 1/100 shutter my "pixel peeping" would see the movement of the moon especially when using longer lenses & or TC's. This could possibly counter this. Although I will admit I am relatively new to shooting the moon and might (reads: most likely) just be finding misguided applications of the technology. You know like Windows Vista UAC.

Wow. What an innovation Pentax! You really did something with this...
I wouldn't have much use for the astrophotography side of it, but the GPS would be nice...

A full moon is very bright, even in long lenses. I've never tried to photograph it, but in my telescopes, it's too bright to view without a filter to knock down the brightness.

But it's those long exposures of the deep sky that astrophotographers can get, that will take your breath away.

It's funny someone in the other forum made a thread about this idea of using SR to track stars. And now Pentax made it possible. I only hope it will support the K-x.

Unfortunately, according to the press release, the device works only on the latest generation of cameras (K-5, K-r, 645D).

Further, as far as I can tell right now from what's been released, the Astrotrace function will only work with bodies featuring the newer SR system (i.e. k-r and k-5, and not the 645D, which does not have in-body stabilization).

It seems to me Pentax is now really leveraging the benefits of a floating sensor. First it was composition adjustment for tripod use, now rotating the sensor to track stars. Nice!

I wonder what else they can do with this technology.

It's a really neat idea, however the maximum travel of the sensor will limit, to some extend, the exposure time. anything over about a minute will probably be too much. Still, that's pretty neat!
