Down to the wire, let's add a few more. How can we have a constellation of the month thread with Triangulum and no M33? I hope to replace this one with a new sketch with the 14" next new moon. NGC 604 is down at the bottom.

NGC 246 is a very interesting and beautiful planetary nebula 1,600 light years away in Cetus. It’s fairly large and bright so not difficult to see, but the details are a bit difficult to hold. The disc is distinctly mottled and appears almost transparent with an illuminated gossamer film. An Oiii filter helps and so does magnification, but it’s not so bright to handle the dim filter and smaller exit pupil. I used a Televue 1st gen Bandmate Oiii filter with a wide passband to give the view a “gentle” filter to enhance details but not darken the view much.

Raul already posted an awesome detailed sketch of the planetary Jones 1 in Pegasus. I'll add another view in a bit wider field.

Thanks Andy.I kept hoping that someone would come through with m33 and ngc 246. These were worth the wait!

Great idea Andrew to get in under the wire.  Here's my view of M33 and some more last minute entries from Pegasus, including one of my favorite barred spirals.
