Astro Photography

Since 2021 I’ve discovered a new hobby: Astro Photography.
It all started by getting a present from my daughters. A book called “Kijk omhoog” (Look Up) from Frank Deboosere.
After reading it, the urge to by a telescope grew. Knowing in advance I would take pictures I bought the equipment suitable to start with it.
the learning curve is steep, but once you get to know the scope and the settings, including all that is need to get a good picture (lights, darks, bias, flats, stacking,…), it’s a lot of fun.

Sii = (Ha*1.024390243902439)
R=.4*Ha + .6*S
G=.4*Oiii + .3*Ha + .3*S
B=Oiii

Sii = (Ha*1.024390243902439)
R=.4*Ha + .6*Sii
G=.4*OIII + .3*Ha + .3*Sii
B=OIII

R=Ha
G=OIII*.8+Ha*.2
B=OIII*.85+Ha*.15

R=Ha*0.76 + Sii*.24
G=OIII
B=OIII+.85+Ha*.15
