Starglow Ceiling provides the most accurate method to create an astronomically correct star ceiling available on the market.
Our Stamp places stars in their correct position and apparent brightness close to professional planetarium quality. We understand that most of our Customers are very happy with our random Night Sky starfield but some are very interested in ensuring an accurate representation of the true night sky. If you are such a person, then the information below is for you!
CORRECT CONSTELLATION POSITIONS
The difficulty of creating an accurate star ceiling at home is that the real night sky appears as a dome yet our ceilings are flat. Most products available on the market today do not take this major problem into account and simply place constellations in rough and distorted positions. Typical products provide some kind of projector to shine star images onto the ceiling with instructions to then stand on a ladder and place glow paint or glow stickers on the star lights by hand. This works fine for constellations on a ceiling directly overhead - except for the ladder climbing and Michelangelo upside down painting - but since a ceiling is flat, the farther away the constellations are from directly overhead the more distorted they become. Orion the Hunter for example would appear very tall and thin. Other products provide individual constellation templates you can shine a light through but do not provide a method to ensure the constellations are in their correct positions relative to each other.
How did we solve this problem?
We began by using an excellent star atlas created by the well respected Wil Tirion. Mr. Tirion created many atlases and lucky for us he created an atlas that converted a typical curved line atlas that matches the curve of the apparent sky dome into a vertical and horizontal grid. The result is stars and constellations now appear as they would in the real sky applied to a flat surface.
We chose a flat stamp so we could accurately replicate the star positions on a flat ceiling but needed to convert the atlas to our stargrid. We very carefully and by hand charted thousands of stars to create our "upside down atlas" and developed a detailed coordinate star chart with simple instructions on where to place our Starpegs which when stamped, paint the stars in their correct positions. And if you understood all that you're doing great!
CORRECT APPARENT STAR BRIGHTNESS
So how do we ensure stars on your ceiling are created to match their apparent brightness in the real sky? Star brightness is rated as magnitudes with the brightest being magnitude 1 and the faintest ones magnitude 5 (darker locations allow you to see fainter magnitudes). We developed Starglow Ceiling to accurately represent stars to the 5th magnitude and created color coded Startacks to match these apparent magnitudes. Our star charts provide instruction on where for example to place a "red" star or a "white" star. You will then apply the appropriate amount of Starglow Paint to the Starpegs before stamping. Our patented Starpeg design creates a "cone" shaped star on your ceiling which produces the clearest and brightest glow possible and helps to ensure higher brightness accuracy.
The result is an astronomically correct star ceiling that will rival many planetariums!
