Here is my First ever colour image in Narrow Band using the Hubble Palette (kind of).
I am still learning how to process  images taken through narrow band filters, so I probably got a bit carried away 🙂

Eta Carinae nebula: Total exposure time is approximately 1.5 hours with 6 x 5 minute exposures for each narrow band filter:  Ha, Sii, and Oiii Filters.
