Summary[edit]
| Description |
Lambda Cephei—demure and largely ignored in visible light—stands out with its bright red shock wave to WISE's infrared eyes. Kaler, as usual, has a nice way of describing the star if you would like to know more about it. Click! For the processing on this one, I separated the four WISE channels into two distinct groups, treating each group as if it was a two-channel, pseudogreen image. The dust group (W3 & W4) is given preference for visibility while the star group (W1 &W2) is only faintly applied on top of the dust group as an additive layer. I also learned about some new artifacts in WISE imagery called latents which are leftover spots on the detector where bright sources were previously imaged, so I got rid of those along with the usual annuluses, otherwise known as filter ghosts. Dust Group: Red: W4 (22 μm) Green: pseudogreen Blue: W3 (12 μm) Star Group: Red: W2 (4.6 μm) Green: pseudogreen Blue: W1 (3.4 μm) North is up. |
