Description

NGC7331 and friends

4430x1.5sec L for the core
108x600sec L for the rest
5x600 R/G/B using baader RGB filters
9x600 Baader HA

Equipment:

CEM70
C11 SCT
Starizona 0.63x reducer
ASI 294MM pro
ASI 174MM pro guiding
Omegon OAG


The processing involved stacking 4400 1.5 sec images using DSS to capture the details in the core of the galaxy. The resulting image was sharpened, processed and blended with the long exposure luminance. The HA was really tricky to process, the core of this galaxy emits a lot of light in the Ha wavelength and it was making everything look orange.

I love this target, it's so rich in details it's a pleasure to capture and process
