IC5070 - The Pelican Nebula, 07.10.2004 (21:16 -00:04 UT)
Resolution: 11.24 arcsec/pixel
Object altitude: 59 - 33
Camera: SAC8 + 0.6x Mogg focal reducer
Telescope: 80mm F5 Skywatcher refractor
Result focal ratio: F3
Result focal length: 240mm
Filters: Astronomik H-alpha
Exposure: 65x14s (gain 100%, Hi-Res, Amp Off), mosaic of 6 frames
Capturing: K3CCDTools 2
Processing: K3CCDTools 2, K3APEX, Loreal, iMerge, Corel PhotoPaint
Seeing: lim.magnitude for naked eye ~4, medium transparency, some clouds
Conditions: temperature 10.9C, 60% humidity

Processing:
1, Stacked by K3CCDTools 2 with 16-bit DF (80x14s) and artificial FF
2, Histogram stretching and gamma 2.0 in K3CCDTools 2
3, Rotation (to eliminate wrong polar alignment) in K3APEX
3, Mosaic from 6 result frames created in iMerge
4, "black ghost" on the right side of bright stars were removed by Loreal
5, Final resizing, contrast enhancement and adaptive unsharp mask Corel PhotoPaint.


Colorized version created from the above picture:
1, Grayscale image converted to RGB
2, G and B layers cleared - the result is RGB red colored picture
3, Gamma 2.40 applied to RGB red
4, Grayscale and RGB red version are layered in PhotoPaint and used overlay merge mode

IC5070 - The Pelican Nebula - "Neck" detail

I found the Pelican's neck region very interesting.
The following detailed photo covers the area from the above picture marked by red rectangle.


The detailed photo is magnified 5x in comparison with the whole Pelican photo.

08.10.2004 (21:55 -22:43 UT) + 09.10.2004 (23:18 -23:51 UT)
Resolution: 1.32 arcsec/pixel
Object altitude: 49 / 36
Camera: SAC8
Telescope: 8" F6 Orion Europa Newtonian
Result focal ratio: F6
Result focal length: 1200mm
Filters: Astronomik H-alpha
Exposure: 48x23s + 76x23s (gain 100%, Hi-Res, Amp Off), "mosaic" of 2 frames
Capturing: K3CCDTools 2
Processing: K3CCDTools 2, K3APEX, Loreal, iMerge, Corel PhotoPaint
Seeing: lim.magnitude for naked eye ~4, medium transparency, some clouds
Conditions: temperature ~7C, 58% humidity

I had to stop imaging in 8.10. because clouds covered the whole sky. That's why I finished my imaging a day later.

Processing:
1, Stacked by K3CCDTools 2 with 16-bit DF (80x14s) and artificial FF
2, Histogram stretching and gamma 2.0 in K3CCDTools 2
3, Precise rotation of the frame from 8.10. to fit the frame from 9.10. in K3APEX
3, Mosaic from 2 result frames created in iMerge
4, "black ghost" on the right side of bright stars were removed by Loreal
5, Final resizing, contrast enhancement and adaptive unsharp mask Corel PhotoPaint.

Colorized version created from the above result.
