Description

An infrared, pseudogreen, red light view of a beautifully symmetrical bipolar preplanetary nebula (are we just calling these 'young' planetary nebulas now?). The blue appearance is due to the filters used. Note the blue outflows are glowing, ionized gas, not dust. There is a very faint but curious stray bit of gas pointing directly back to the central star down and to the left of the nebula.

Thumbnails in the HLA are of awful quality and obviously created with some error but the actual data (acquired through DADS) is very nice looking.

This object was also imaged for <a href="http://archive.stsci.edu/proposal_search.php?mission=hst&id=10536" rel="nofollow">proposal 10536</a>.

North is NOT up. It is 9.77° counter-clockwise from up.
