Astrophoto

Rosette nebula in the hubble pallet	This is my first image using the Hubble pallet (Ha = Green, O3 = Blue, S2 = Red). The use of narrowband filters allows fine detail to be captured of this star nursery some 4500 light years away. The FOV of this image is a little less than 2 degrees by 2 degrees or about the size of a fingernail at arms length. http://www.astrobin.com/34820/
