NGC 6888 in H-alpha and O-III light.



This was hard to process...
I have problems to have images calibrated with Flats, Bias and Darks, so much extra work there to have images balanced.
-
O-III, ionized Oxygen, really add forms to this image.
I will shoot S-II, even though there is much that in the Crescent itself.
I'll like to make this image to HST-palette as well.
- Camera QHY9, Optics Meade LX200 GPS 12" forced to @ f4.65 Guiding with SXV-AO active optics unit 11Hz Filter Baader H-alpha 7nm
H-alpha 4.5h 20min subs
O-III 2h 40min 20 min subs

A new project, NGC 6888

I have started a new project with the NGC 6888.
So far there is 4,5h of H-alpha.
Image going to be a three band narrowband image, I have allready 4,5h O-III light for this.

M27 in two palettes

Natural colors
In a Hubble palette, S-II=Red, H-a=Green and O-III=Blue -

I was able to shoot data for other channels and more lights for H-alpha, last night.
Same data than H-alpha version in last post.
Additional two hours for H-a, now 4,5h together,
6x600s, binned 2x2, for O-III and 2x600s, binned 3x3, for S-II.
-
More information about the target HERE.

O-III channel is very strong. Note. there is interesting looking shadow at three a clock position.
Hint of an other shadow can be seen in a nine a clock position too.
