Astro Aperture requirements using astrotracer (milkyway photos)

It is possible to achieve decent results with Astrotracer, however I've found what other posters here have noted. Calibration can be hit or miss. Here in Hawaii, some of the lava fields have high iron content, making it almost impossible to get a calibration as a result of poor compass function. I've even found moving 10-15 feet can make the difference between obtaining a Calibrated screen or Failure.

I've also found highly touted ultrawides, such as the Samyang 14mm 2.8 to have soft corners and coma tails at 2.8, requiring stopping down 3.5 - 4 to obtain adequate sharpness.

All in all, my IOptron Skytrackers functions much better than the Astrotracer function.
