ASI290MM first guiding job

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).

Testing polar alignement

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

The PHD2 Guidelog as seen over almost the entire night, 7hours of guiding

The guidelog in more detail, this is another section of the guiding over 2 minutes

The calibration cross of PHD2 seems pretty much ok
