BHR71 | NIRCam #JWST

I already have the versions with the 4 filters; I've rarely worked with f212n, but this time it does make a slight change in the image.
In this video, I'm omitting the f360m and f480m lenses. I'll be cropping each one in the central region.

BHR71 | NIRCam #JWST

The first image uses the f360m and f480m filters separately, using the same color and highlighting specific areas.
The second image is a combination of the two previous images.

The f200w is the blue color in both images.

New paper alert! We image the ionized jet of a protostar, BHR71-IRS1, for the first time! We find neon, argon, cobalt, iron, nickel, sulfur, all launched at >100 km/s from a young star. #JWST #webb
