This is the setup for another test on my PST Etalon (No 4)
It was another cloudy and turbulent day. Blue skies in the opposite direction.
This is what I caught:

Nice work, Alfred. This is actually a good reference image for when I try a close-up with my PST etalon.

Good result. Etalon looks slightly red to me.

Hi Mark,
I struggle with setting a "right tilt". Hence I am not surprised if it was off-band. Can you teach me how to tell that the etalon has been tuned beyond 656.28nm into the red?
Thanks.
Alfred
