Back to nebulaes, galaxies are so tough from our polluted sky...
A grand total of 14h : 8h HA and 3h SII & OIII. A record for us !
HA with 20mn exposures, 10mn for sulfur and oxygen.
Still using the Tak FS60 and the Atik314L+ loaded with Astrodon 5nm filters. And still from our balcony 10 kms from the Eiffel tower with the LX90 as a mount.
Most of the exposures have been done under a strong wind but goot seeing. Some field rotation on the first HA batch as well, i corrected the alignment with PoleAlignMax in between.
Layers are HSO.
One of my best i think !
