There was a time when no colour planetary camera could approach the sensitivity and detail that can be captured by a mono camera with filters. The world is changing and the newest generation of colour CMOS planetary cameras are closing the gap. Using the same kit apart from the cameras I've scaled these images to match each other in size to compare the detail captured. On the left is 20minutes derotated of the colour camera, on the right just 5 minutes derotated of the mono camera. I have matched the mono as far as posible to the colour of the colour camera as that is a more accurate representation of the colour of Mars.
For the moment mono still wins on detail recored but the colour may give a smoother more accurately toned image. In both the whitish clouds round both Olympus Mons and the Tharsis mountains can just about be seen on the right hand side.
I am still working on the best way to process the colour camera images so I may update this comparison in due course.

M27 is the first planetary nebula ever discovered. Charles Messier discovered it in 1764. William Herschel invented the name "Planetary Nebula" around 1784 because he found them to resemble his newly discovered planet, Uranus.

M97. The Owl planetary nebula is about 3.7 arcminutes across in our sky but is actually 0.91 light years in diameter. It lies about 2600 light years distant. The central star has shed its outer layers which glow either red (hydrogen) or green-blue (oxygen) lit by the intense UV light of the remnant white dwarf star in the centre. Eventually, the star will cool and the gas will expand until the nebula fades away. It estimated that the nebula is about 6000 years old based on its size and expansion rate. Our own Sun may eventually suffer a similar fate.
A gravitational effect has formed a constrained tube of gas near the star before it expands into a sphere. We are looking down at about 45 degrees to the axis of the tube, these effects produce an "owl face" from our perspective.
Barred spiral galaxy M108 is about 45 million light years away and is almost edge on from our perspective. It’s 8.7 x 2.2 arcminutes diameter in our sky. It lacks a prominent core or bulge but has numerous dark dust lanes. It’s possible to see
a small yellow core at its centre (yellow or red stars tend to be old and mature) brownish dust lanes, pink hydrogen alpha zones and two bright blue "stellar associations” of young intensely bright stars at this magnification.
A Type II supernovae was observed here in 1969.

This planetary nebula has a very unusual shape.
The central star is moving, and this causes the ejected material to pile up in one direction. This part is brighter.

had a go at putting an orb in a spin, got a good orb a good spin but may need to lower the angle of the camera as it was about 20 feet up looking down on it, and you lose the top of the orb.
This painting is based on the mural i did in India in January 2017.
It was about the motion of celestial bodies in the Universe.
This painting is about Earth motion.

Here is a view of an ancient planetary nebula in the constellation Cassiopeia and known by several names including Sharpless 2-200 and The Bear Claw Nebula. It was discovered in the early 1980’s by examining the 1960’s Palomar Observatory Sky Survey. You can read more about the discovery in an article titled “A newly discovered nearby planetary nebula of old age” by Authors: Weinberger, R., Dengel, J., Hartl, H., & Sabbadin, F.

A small faint planetary nebula can be found near the centre of M22. Planetary nebulae located within globular clusters are very rare.
The Helix nebula is an example of what our sun may look like once it has run out of fuel (hydrogen). As a star runs out of hydrogen it starts to expand and eject its layers. Says wiki, "The Helix Nebula is an example of a planetary nebula, formed by an intermediate to low-mass star, which sheds its outer layers near the end of its evolution.
The remnant central stellar core, known as the central star (CS) of the planetary nebula, is destined to become a white dwarf star. The observed glow of the central star is so energetic that it causes the previously expelled gases to brightly fluoresce. Yet this star's size is only about 2.5 % that of our sun and possibly of its original.
This particular nebula is one of the closest ones to us at around 650 light years. The object has been given numerous nick names such as "The eye of God" or "The eye of Sauron"
I took this very close to a full moon but got better results than I thought. It's basically in Hubble palette with some blend modifications (Red - 50% Sii and Ha; Green - 15 Ha and 85 Oiii; Blue - all Oiii) to make it look RGBish. Stars are so so as there was very little exposure (3 min per filter). Acquisition is about 3 hours of combined SHO taken from Chile with a 10 inch Astrograph and a ZWO ASI 6200 (bin2). Thanks for looking.
This eerie, dark structure, resembling an imaginary sea serpent's head, is a column of cool molecular hydrogen gas (two atoms of hydrogen in each molecule) and dust that is an incubator for new stars. The stars are embedded inside finger-like protrusions extending from the top of the nebula. Each "fingertip" is somewhat larger than our own solar system. The pillar is slowly eroding away by the ultraviolet light from nearby hot stars, a process called "photoevaporation." As it does, small globules of especially dense gas buried within the cloud is uncovered. These globules have been dubbed "EGGs" -- an acronym for "Evaporating Gaseous Globules." The shadows of the EGGs protect gas behind them, resulting in the finger-like structures at the top of the cloud. Forming inside at least some of the EGGs are embryonic stars -- stars that abruptly stop growing when the EGGs are uncovered and they are separated from the larger reservoir of gas from which they were drawing mass. Eventually the stars emerge, as the EGGs themselves succumb to photoevaporation. The stellar EGGS are found, appropriately enough, in the "Eagle Nebula" (also called M16 -- the 16th object in Charles Messier's 18th century catalog of "fuzzy" permanent objects in the sky), a nearby star-forming region 7,000 light-years away in the constellation Serpens. The picture was taken on April 1, 1995 with the Hubble Space Telescope Wide Field and Planetary Camera 2. The color image is constructed from three separate images taken in the light of emission from different types of atoms. Red shows emission from singly-ionized sulfur atoms. Green shows emission from hydrogen. Blue shows light emitted by doubly-ionized oxygen atoms.

Being nearly the largest vessel in the fleet holding position at a planetary defense station, the Horizon Is a combat ready vessel ready to deploy smaller vessels to defend the UIP's. (United Interstellar Planets) It among many other vessels hold the defenses from all Aliens and Humans looking to destroy them. The Horizon was first put into service in 2186 as the very first of its design and structure. Since that time the Horizon has fended off 7 attacks on the Planets. This is a vessel that will go down fighting!

The Police Striker is one of the most common ships in the Confederacy Galactic Police Force. It mostly patrols the outskirts of major Cities and Industrial areas. Always ready to strike at suspicious activity. Antigrav engines keeps it in the air while the quad thrusters gives it it's deadly speed. The wings are mainly for stabilization but can also be used for tight twists and turns. The Striker can fly in zero g but performs best in an atmosphere.

The Planetary Mining Rover is a mass produced rover used extensively throughout the galaxy. The equipped dual drilling arms are capable of breaking through some of the toughest materials known to man. A cargo compartment in the rear of the rover enables the P.M.R. to transport materials back to base.
Narrowband image with Hydrogen alpha filter of the planetary nebula nearest to Earth.
In this image, nuclear fusion has ceased in the central star as the available fuel has run out and the outer layers of the star have been shrugged off.
Gases in the envelope layers glow under the glare of the intense UV light radiating from the White Dwarf remnant of the central star.
Its thought that the NE outer rim (lower right) is glowing more brightly as it encounters interstellar gas and the friction of the collision causes heating.
Within the "eye" of the nebula are hundreds of "comet" shaped features that all point back to the central star - astronomers are uncertain if these represent gas outflows or UV photodissociation of gas.
The central star exploded 10600 years ago - as worked out by reversing the gas flow velocities.

With the public release of some of the initial JWST images it is possible to download and process the raw data yourself.
Images were made at six infrared wavelengths and so the choice of mapping these images into an RGB colour space is left up to the end user.
In this I've tried to bring out the detail in the regions of this planetary nebula, formed as a star throws off its outer layers.
