Still stuck with Elongated stars.

Tonight here is what I did to try to fix the elongated stars in my images following the changes I’ve made on my setup:

1. Tightened the Guider focuser tension screw
2. Made sure everything was well screwed and solid
3. Re-leveled the Pier
4. 3 stars alignment with the CGEM
5. Polar alignment with the CGEM software
6. Lauched PHD Guiding with very good guiding results (i.e. OSC: 0.4, RMS: 0.3)
7. Took a four minute test shot…here is the result…
8. Next steps: revert back to the piggy-back configuration. More to come.
