| Veil Nebula
in RGB/HOT color |
Telescope: |
AP-130 at F/5.4 (700mm)
and AP 600 GoTo Mount with STV on AP Guidescope |
| Exposure: |
ST-10 with CFW-8 and extra filter drawer RGB:
Red = 6 x 6 mins, Green = 6 x 6 mins, Blue = 6 x 10 mins
HOT: Ha Red = 3 x 30mins, OIII Green = 1 x 30 mins, Hb Blue = 1x30 mins
IDAS Narrow-Band
Nebula Filter (NBN-PV48) used in combination with SBIG filters to produce
OIII Green and Hb Blue for HOT color
space image. |

| Normal RGB image used as base HOT color
space as proposed by by Thor Olson was developed using narrow band filters for
Ha, OIII and Hb. The HOT image was then used as a 75% Lum Channel and 68% Screen
Channel for the RGB image. This combination preserved the star colors while
enhancing the
nebula. |
