I guess the picture below says it all !! RMS values of 0.30″ and 0.26″. The mount was setup in the garden that same night, using PoleMaster to align (one 7-minute session). The PHD2 Guidelog mentions a pole error of 0,5′ I guess that is 30″. Not bad for spending 7 minutes on aligning. Works like a charm.
This is no doubt rather good guiding. I’m happy with this result: a good combination of the ASI290MM smaller pixels and the old Soligor “free” 400mm F 6.3 DSLR telelens (I got it as a gift from a neighbour who found it on a flee market).
To prepare for the clear nights to come, I made use of a brief clearance between clouds to test the polar alignement. I connected the ASI174 to the Esprit f=840mm and let PHD2 guide for 4 minutes. The Polar Alignement stabilized on 4 arc minutes
Is that good enough?
And the result of the next night: the PHD2 Guidelog analysed with PECPREP
