<p>My favorite thing about &lt;a href="<a rel="nofollow" class="external free" href="http://www.spacetelescope.org/images/potw1102a/">http://www.spacetelescope.org/images/potw1102a/</a>" rel="nofollow"&gt;NGC 6886&lt;/a&gt; is that its number designation is as palindromic as it the nebula itself. The central star is just barely visible with this processing. It's &lt;a href="<a rel="nofollow" class="external free" href="http://stars.astro.illinois.edu/sow/n6886.html">http://stars.astro.illinois.edu/sow/n6886.html</a>" rel="nofollow"&gt;easy to miss&lt;/a&gt; but it somehow shows up in the f555w data even though it's invisible in the other two channels.
</p><p>Corners are missing data.
