Description

A new version of my last shot of NGC891 : I slightly improved the image for a maximum zoom on the small details

--------------------------
I am happy to post this new shot composed of 2 different setups, the RGB come from my fisrt newton 10'' from the summer 2018, and the luminance from my new setup with the 12''newton .
The 8th of October in the evening, I just started the night as usual with some SHO subs because of the moon , and it shows good FWHM, so I decided to modifiy completly my schedule and shoot this very nice galaxy, after the moonset !
I had only time to shoot new Luminance but it was worth it ....

From Lacerta Newton 300/1200
56 Light subs @180s (gain 0 and -20°c )

From Lacerta Newton 250/1000 from summer 2018
15 Red subs @180s (gain 139 and -20°c )
15 Green subs @180s (gain 139 and -20°c )
15 Blue subs @180s (gain 139 and -20°c )
