Thanls Gabriel,
Really appreciate how you share your experience !
Try astrophotography using my 36" Fullum alt/az is a target for future and with your explainations it becomes clearer what to do.
And the ressource is really great !
I'm currently in the gear ratio tracking improvement phase, which you pointed out to be a must have before thinking of astrophoto.
When you say "the unguided performance seems to be about 2.0-2.5 arc seconds RMS" I believe this error of 2.0-2.5 arc seconds is for a amount of time, right ?
Per seconds ?
For example you measured that the unguided star was drifting in the field for 20' in 10 min and so 20*60=1200 arc second in 10min so? 1200/(10*60)=2 arc seconds / s, right ?
Just curious what accuracy you achieved to compare with my actual precision of tracking.
Regards
Rapha?l
