I have latest firmware (tested last night), and still fairly abysmal frame acceptance rate. Probably about 25% of time spent on object. This is probably my main gripe with the scope now - the effectiveness of the time. Too many frames lost. Also, that it were possible to change dither to be by time rather than every 5 frames... perhaps also tuning about the sensitivity of throwing out poor frames... or weighted stacking - so lower quality frames get lower impact on the final stack... Anyway, I hope this is all corrected in a near-term software update.
Also: I wish it were possible to also have 5 second exposures (for objects with plenty of stars, such as open or globular clusters like M46 or M35, etc.). Also for planetary nebula (like that in M46).
And you guys did an amazing job with this game-changing device.
(I have 10+ other telescopes - but none set up in 2 minutes and tear down in 1...)
