Reflection Nebula NGC 7129 in Cepheus

Here is a 68 minute combined exposure of the reflection nebula NGC 7129 in the constellation Cepheus. It is on the small side, measuring about 7’ x 7’ and has an apparent magnitude of 11.5. Without using filters, I don’t think I could get much more details using my stock Canon 6D but may add some additional time to it.  A young open cluster is causing the surrounding nebula to illuminate.

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.

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/).

Messier 97 – The Owl Nebula

The Owl Nebula (also known as Messier 97, M97 or NGC 3587) is a planetary nebula located approximately 2,030 light years away in the constellation Ursa Major. The owl-like appearance is caused by various formed shells expanding away from the central star.

Tech Specs: This image is composed of 23 x 60 second images at ISO 3,200 with 4 x 60 second darks and 4 x 1/4000 second bias frames using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Guided using a Canon 400mm lens and ZWO ASI290MC camera. Imaging was done on April 14, 2017 from Weatherly, Pennsylvania.
