M20 Trifid Nebula
I used raw images from the HST-WFPC2 taken in three bandwidth - F656N - F502N and F673N - to make this trichromy of M20, the Trifid Nebula.
Upper-right there is a wide angle view of the M20 with superimposed the field of view on the WFPC2.
This fits liberator image is not available for sale.
