It's a combination of good Ha data and poor RGB data, or poor Oiii data. RGB was taken a few days ago, under bright moon.
I thought about processing Ha/Oiii in the usual hubble palatte color, but I decided to go this way because, it's supposed to be a heart.
Thanks all for viewing! Advice and suggestions are very welcomed.
astro-tech x0.8 ff/fr
nikon d5300 full-spectrum
idas lps d1 48mm
baader 2" 7nm ha
baader 2" 8.5nm oiii
ha: 5 hr with 10 min subs
oiii: 4 hr with 10 min subs
rgb: 4 hr with 3 min subs
@ ISO 200, FL 384mm, f/4.8
all done in Pixinsight other than final color touch
color was tweaked in Photoshop
L = 0.3 * ha + 0.7 * l
R = iif( ha>r, 0.8*ha + 0.2*r, 0.5*ha + 0.5*r)
G = g
B = b
- Ha/Oiii (made starless versions of each when blending for color)
L = ha
R = 0.3 * oiii + 0.7 * ha
G = ha
B = oiii + 0.15 * ha (this should have been 0.85 * oiii + 0.15 * ha. This mistake was the reason why the bright parts are blown out white)
I honestly like the HaRGB the best. Although the bi-color imaging with Oiii filter is interesting, shooting Oiii with a DSLR is just not fun... It requires extreme processing, which is stressful.
Although shooting RGB is troublesome here, Ha data is always so good regardless of the moon, light pollution, so HaRGB often turns out alright. (plus I really like the natural and colorful stars!)
