Which size is right for your space?
- Living room (above sofa): 48x32
- Bedroom (above headboard): 36x24 or 48x32
- Dining room: 36x24 or 48x32, depending on wall size
- Home office or den: 30x20 or 36x24
- Large foyer or entryway: 48x32
- Hallway, bathroom, or gallery wall: 18x12 or 24x16
When in doubt, go bigger than you think. The art, including any frame, should fill about ⅔ the width of the furniture beneath it. Sizes listed are the photograph itself; framed paper prints, with a 2" mat and frame, are about 3–5" larger in each direction.

Framed prints arrive ready to hang
Framed paper prints are matted with a 2" white mat and protected by non-glare acrylic, so the image stays clear without reflections from windows or lights. Acrylic is lighter and safer to ship than glass, and every framed print arrives with hanging hardware already attached.
MetalPrints with a float mount or frame also arrive ready to hang.

About this photograph
The "NGC 6888 Crescent Nebula HOO" photograph reveals a stunning celestial landscape, showcasing the intricate beauty of this stellar demolition zone. Captured from my urban backyard under Bortle 8 skies, this image is a result of 183 carefully stacked subframes, processed in a hydrogen-oxygen-oxygen (HOO) color palette. The vibrant hues accentuate the gases that define this nebula, allowing you to appreciate the cosmic dance of light and matter that unfolds 4,700 light-years away in the constellation Cygnus.
As I worked on this piece, I was struck by the dynamic interplay of colors and textures, each layer telling a story of stellar evolution. The Crescent Nebula, discovered by William Herschel in 1792, is a reminder of the universe's ever-changing nature. The potential for this nebula to glow anew as it undergoes transformation adds a layer of intrigue, inviting contemplation about the life cycles of stars.
NOTE:
The majority of photographs of nebulae are in a false color palette. False-color photographs of nebulae are essentially color (RGB) photographs whose color channels have been mapped to specific emission lines. In these images, each color can represent a specific element. In other words, a false-color image of a nebula tells us exactly what it’s made of. There are many emission lines, but the three most photographed by astronomers are hydrogen-alpha, oxygen-III and sulfur-II. These emission lines are captured by using narrowband filters which only let through the light at very specific wavelengths, typically most of my photographs are taken with filters allowing a bandwidth of 3µm.

Mapping Hα, O-III and S-II to red, green and blue is problematic when two of them are red, one is blue/green, and none is pure blue. Astronomers deal with this by using false color — one or more of these elements will have to take a hit for the team and take on an unnatural hue. The HOO color palette assigns red to Hα, green and blue to O-III: red is accurate, and green and blue are false. Sometimes, some astrophotogers add some Hα to the O-III in the green channel for a synthetic green. The point of this color palette is to emphasize specific nebula structures so that they are more prominent. This photograph uses the HOO color palette, hence the reds and blues you find in the photograph.
