GSSP and Sierra Buttes 2007 (Planetaries)

Location: Lassen. Devastated Area parking lot.
Telescope: C9.25"

To compare from Steve's observation, I got a look at NGC 6337 using a C9.25". The low elevation of this object, I would imagine Steve's secondary cage assembly was probably scraping the ground. :)

NGC 6337: Planetary nebula in Scorpius. Scorpius was hugging the ridge. With the OTA parallel to the ground, got a nice view of this planetary nebula (no air turbulence). It was a challange object as it required an OIII filter. At a mag 12.3. Fairly bright, roundish, brightness was uneven, brighter on the northern edge (106x). Using 138x shows a ring shape with difficulty part of the time.

And.....I gotta include this find;
Using the C9.25", saw spiral structure in NGC 6946. This is the galaxy that is well known as it shares the field with an open cluster (NGC 6939). Galaxy is located at the Cepheus / Cygnus boarder. NGC 6946 is bright, face-on, very large, has a low surface brightness, oval shape elongated east-west, on each side of this galaxy there are two broad curving arms, eastside curves south, westside curves north. Awesome!
