M 76, the "Little Dumbbell Nebula"
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.
The "Little Dumbbell", Messier catalog number 76, also known as NGC 650/651, the "Barbell Nebula or the "Cork Nebula". This bipolar planetary nebula locates in constellation Perseus.
Distance is about 2500 light years and average dimension is 1.23 light years across.
Smallish apparent dimensions, 2,7 x 1,8 arcmin, makes this target difficult to image.
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.

IC 63 as an animated 3D
Animations are made by creating artificial parallax to an image. Then two images are animated together by using conversion web service, Start3D. There can be some artifacts in images, due the experimental nature of this work! The volumetric models are based on some known facts and an artistic impression.
Please, let the images load for few seconds to see them animated!

IC 63 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.
