Planetary Nebula NGC 1501 in Camelopardalis

NGC 1501 lies in the constellation Camelopardalis (the Giraffe) and is roughly 5,000 light-years away. The internal complexity of this nebula is only hinted at in my image, you can see the various light and dark bands inside. It has also been referred to as the Oyster Nebula, from the bright central star peeking out of the cloudy shell around it. The surrounding cloud was formed when the central star blasted off its outer shells.

Planetary Nebula NGC 6891 in Delphinus

NGC 6891 is a planetary nebula found in the constellation Delphinus, it has a diameter of roughly 14 arc-seconds and is magnitude 12.0 (depending on the reference used). I found a really interesting view of this PN using several thousand one-second stacked images, looking forward to trying that out next session.

NGC 7354 Planetary Nebula in Cepheus

NGC 7354 is a planetary nebula in the constellation Cepheus. My 12” telescope just starts to bring out some details in the inner and outer bands with a 16 minute total exposure. Zooming in just starts to bring out the 16th magnitude central star. I have seen several distances mentioned to NGC 7354 with the average being around 4,000 light-years from Earth.

Planetary Nebula NGC 6572 in Ophiuchus

This is the bright planetary nebula designated NGC 6572 in the constellation Ophiuchus. I was not able to bring out any inner details of this planetary nebula during this imaging session. I’m guessing many shorter exposures are needed. I have seen some posts on CloudyNights.com that show some sketches of an outer shell – worth checking out if you have the time (https://www.cloudynights.com/topic/550264-ngc-6572-outer-shell/).
