Originally posted by Painter I’ve been searching for any information on what the difference is between setting the astrotracer function on the K3 III with the OGPS-1 to Type one or Type 2 but can’t find anything. Anyone know how the two behave?
Type 1
Tracks and captures celestial bodies in B mode using the Shake Reduction function.
Type 2
Tracks and captures celestial bodies with settings suitable for starscape photography in B mode using the Shake Reduction function.
I've yet to try it, but I suspect it does "exactly what it says on the tin", which, unfortunately, possibly only makes sense if you've used an earlier (KP or K-70) Pentax for the same job.
These had a specific "Astrophoto" setting, (not to be confused with the "Astrotracer" function), designed to retain the original colour of the stars and enhance the nature of the blackness of the sky whilst retaining most detail … probably "Type 2" in "K-3iii speak". Useful for making "Star-trail" pictures or movies, ("StarStream"), for which there was also a separate setting which was used without the O-GPS1 module.
It'll be interesting to see if these Modes on the K-3iii will actually work without the O-GPS1 fitted, thereby giving the functionality of the earlier models.
Unfortunately, without a tilting screen, I'd anticipate the K-3iii won't be as easy to use, especially for high elevation shots.
Oh for a clear moonless night with no wind
