The Rosette Nebula 🌹
You guessed it, it’s a gassy region forming new stars! I used my new narrowband filters to image this, which gave me data in red, deep red, and cyan.
That meant “interpreting” the data into something that looks pretty, by mapping them onto red, green and blue in different ways.
There are two attempts. The first one using more or less the pallette used for Hubble images, the other a classic “SHO” mapping for sulphur, hydrogen, oxygen onto red, green and blue.
I didn’t get much sulphur data because clouds, so the red channel is very weak in that one. The other one uses a formula to mix sulphur and hydrogen data for the red, so it gets brighter and yellower.
