Both lenses and mirrors can be flattened by dividing them up into concentric

Nice

Instead of two big mirrors, why not have thousands of small ones around the cylinder that direct their light onto fibre-optic cables? Because these cables are flexible, they can take the light to wherever it's needed. The shape of the habitat becomes less important with that kind of design. One could even have such fibre arrays in arrays like solar panels, but instead of generating electricity they pipe the light itself to where it's wanted.

Sounds like a good idea; I'll see what I can do.

Interesting and Beautiful Pictures!

A planet orbiting LBV 1806-20, possibly the most luminous star in the galaxy.



Recent studies indicate it may be a binary star instead of being the most massive, which disappoints me.

Never noticed this before, or knew Celestia could even do this. I made a Star Trek system around Mira. The trouble was the mix up in the shows on nameing their systems. In Star Trek they have been to Mira III and to Mira Antliae V (Dytallix B).
So I made a binary system for Mira (I know it's not scientifically correct, but what in Star Trek travel is?)
Anyway I put Mira Antliae VII so far out from Mira B, that it gets illuminated by both stars.

at least 8 "well-known" stars in the following picture, as seen from a nearby double star system.

Some of you should already know where I am.

Phyrra System – Diomedes

12th July 3091

Located Close to the Magenta system (20.5 Light years) on the Gulf of Tears (1900 Ly from Sol)
Is the Phyrra System. Composed of 2 Planets, Both SuperJovian, called Midas and Gallonigher.
Midas is the most interesting. It has a co-orbiting pair of moons that together make up over 2 Earth masses of material. Diomedes is an Early earth analogue, that is currently undergoing an “oxygen catastrophe Oceanic bacteria and algae have released so much oxygen into the atmosphere that is beginning to aaccumulate although the gas mix is not breathable by Terran life, it is becoming toxic to the native life and a mass extinction is under way.

Acheron is more of a Mystery. Having a stable advance biosphere composed of Chlorine and Phosphor based life, water is toxic and as such the analogue, phosphor has taken over. Phosphor lakes light the night side with an eerie green and when the world is not shrouded in clouds from one of its frequent planetary storms, the lakes are easily bright enough to be seen from Diomedes in the daytime

The system Falls under the dominion of the Empiret Magenta Hegemony and as such, Acheron's unique resources are being harvested. The Empress has seen fit however to establish a research team on the world to try and minimise the impact of mining

there are suggestions that this world was terraformed within the last 10 million years. Superficial evidence for this is the difference in evolutionary complexity of life between Diomedes and Acheron, it is also supported by the existence of Dendray, the moon of Peripolis (Magenta Home System) a world with no biosphere of its own but a similar chlorine mix in the atmosphere.



Peripolis and Dendray are here: viewtopic.php?f=2&t=9581&p=112176&hilit=peripolis#p112176

Impressive landscape. Nice image too.

Thank you much.
I started out altering jestr's alien universe mod and can't seem to get the colors right.

Here is an update,









I could use some advise to improve.

Stunning Reiko ... they look superb to me... maybe a bit more ambient light?
