Hello everyone.
The CDK17 and AOX have been working well in Chile and two nights ago the seeing was quite spectacular.

The thumbnail attached is 3 x 30 min exposures of NGC 6164 through a 3nm Ha filter (full moon), and each of these 3 frames had a good population of stars with an FWHM of less than 1 arcsecond (typically around 0.98).

CDK Subscription is open for anyone interested.
