The star ceiling is finished!!! (well, for now).
After much deliberation, and a few failed attempts, I'm scrapping the ropelight/moulding tray. My test runs were not very successful, there really isn't enough room for the light to spread out, and it really does highlight every single imperfection up there.
So, after putting on another coat of paint, I trimmed all of the strands flush with the ceiling, and lit it up. It looks amazing.
We had some people over today to break it in, they were very impressed.
This is the ceiling, with the strands, lit by the camera flash, the paint is really much darker.
Same view without the camera flash, but room lights on:
Here is a good picture of the ceiling, your looking at it from the "bottom" of the ceiling, towards the top, so all the constellations are upside down. You can see Orion's belt in there. There is one strand representing Mars that I colored in Red, but you really can't see it in this photograph.
Same shot, just with the lens open a little longer, the stars look like they are really twinkling
Here is a bad photo, but shows the room's colors pretty well.
Same photo, lit by the flash, star ceiling on:
Room lights on, no flash, ceiling on:
Last one, this is a close up of Orion's belt, with Mars:
