SH2-3 (Sharpless 3 ) This small but bring nebula offers quite a bit to the imager with any size telescope imaging system. The wide field with capture some nice detail of SH2-3 while picking up a wide range of nebula around it. For the larger telescopes, this one has some amazing structure in the middle that would show some fine detail. The nebula does best with hydrogen-alpha filters but does quite well with the normal red filter. I suspect narrow band filters will also work quite well here since the nebula is on the brighter end compared to others in the catalog.
