Here's a picture I did yesterday using Stellarmate with my AZ-GTI working in ALT-AZ, Nikon D5100, and SkyWatcher 127 MAK, just one exposure of 30 seconds:
I used Synscan driver - just launched Synscan Pro app, did a one-star alignment with a star nearby the Orion nebulae, then goto Orion nebulae and alignment using Stellarmate astrometry.
Look how well defined the stars are, given that this is a somewhat long exposure and that it was in ALT-AZ, and that I only have done a one-star alignment.
I think if I repeat and align over 3 or 4 nearby stars before goto Orion, I could probably get even more dot-like stars and definition at even longer exposure times.
Of course, this opens the door wide-open to shorter exposure astrophotography, I did 10-second exposures, and then the stars were perfect dots.
This speaks volumes about how awesome the AZ-GTI is (especially given its price). This quality might not be enough for professional astrophotography (I think it might, if perfected a little) but it definitely is enough for EAA!
If only the AZ-GTI driver could do the same the Synscan Pro app do, then we would not need that app as an intermediary and we could start even faster: just turn on AZ-GTI, do alignment-sync using astrometry, boom, ready to start working.
Let me know your thoughts,
