Originally posted by awscreo Mm, so I'm reading more of the materials from the Clarkvision. A lot of the Uwa vs fast wide lens seems to be less of a problem taking the Astrotracer in consideration. So I'm guessing using the Astrotracer with a fairly long exposure would allow to gather similar amounts of photons as with a 1.4 lens? I can take an exposure with AT off and mask the foreground into the final image to avoid the blur. I don't have a 1.4 lens for now, and bought 14 2.8 with astro in mind, would really like to use it to it's maximum potential.
I am a newbie here but from my understanding, the astrotracer use the possibility given by SR to move the sensor to follow the subject. The total amount of movement permited is quite small as the primary use is really SR and not an astrotracer.
Specialized gear allow to follow the stars for a much longer time, like what typically included in a telescope.
