RGB and Narrowban data Testing

Original RGB-image from 2007 RGB + Natural color narrowband data 50%/50% RGB + HST-narrowband. Mixed 40% as luminance/60%HST + star color 100% from RGB - -

I found an older RGB-image of Elephant's Trunk Nebula, from year 2007.

It's imaged with a UHC-s filter. this filter gives real Star colors. Camera was a single shot QHY8 cooled astro camera.

Exposures for RGB image:

Meade LX200 Gps 12"@f6.3 with a UHC-s filter, 5x900s only.

-

I have combined this RGB image to a reacently imaged narrowband data.

Interesting looking combination, softer look and real Star colors.
