Sh2-188 as an anaglyph Red/Cyan 3D
You'll need Red/Cyan Eyeglasses to be able to see this image right.
Note, if you have a Red and Blue filters, you can use them! Red goes to Left eye.

Jones 1, an extreme dim planetary Nebula, project finalized
Jones1
Natural color composition from the emission of ionized elements, R=80%Hydrogen, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.
PK 104-29.1, Jones1, a Planetary Nebula in constellation Pegasus.
O-III emission dominates the scene, hence the Bluish color. There is some faint H-alpha emission in a nebula and very dim "blob" of Hydrogen alpha emission just under the nebula. There was no trace of S-II emission.
North is Up and East is Left.
A very hot Central star can be seen as Blue at the center of the Nebula. (Middle one of the Three stars)

I must say, this was the most difficult target ever, due the extremely low surface brightness. I did use my "Tone Mapping" method to dig out all the information. This is one of the dimmest Planetary Nebulae.
There is very few images and information of this nebula around.

Technical details:
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack.
Levels, curves and color combine in PS CS3.
Telescope, Meade LX200 GPS 12" @ f5
Camera, QHY9 Guiding, SXV-AO @ 3Hz
Image Scale, 0,75 arcseconds/pixel
Exposures
H-alpha 9x1200s, binned 1x1
H-alpha 6x1200s, binned 3x3
O-III 16x1200s, binned 1x1
O-III 6x1200s, binned 3x3
Sh2-188, project finalized
New lights added. 12x600s Luminance data with an IDAS LP filter.
The resulting image shows more stars due the broadband component. L + H-a + O-III + S-II are composed to a Luminance channel.
Sharpless object 188
Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.
Sh2-188, PNG128.0-4.1, in constellation Cassiopeia. An asymmetrical planetary nebula was first photographed in 1965, it thought to be a Supernova remnant due its crescent like shape, now it's known to be a Planetary Nebula. Distance from Oulu, Finland, is ~850 light years. Apparent diameter is ~5 arcmin.
There is not too many images of this Planetary Nebula around. I made a HST-palette composition out of ionized elements, H-a, O-III and S-II, I haven't never seen this one presented like that!
I used a special technique of mine to dig out all the information, this is a extremely dim target.
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
