Perseus Double Cluster (NGC 869 and NGC 884)

Here is a view of the famous double cluster in the constellation Perseus (between Perseus and Cassiopeia), they are also designate NGC 869 and NGC 884. This is a two panel mosaic, each panel consisting of six minutes exposure time.

I love the colors in these clusters! During January, this double cluster is near the zenith (right overhead) in Northern Latitudes. I find it best to be observed with binoculars or a low power, wide field telescope.

Picture saved with settings embedded.

Tech Specs: Celestron C6-A SCT telescope and Canon 6D camera mounted on a iOptron ZEQ25GT mount. Imaging was done on November 17, 2016 from Weatherly, Pennsylvania.

NGC 1514 – The Crystal Ball Nebula of Taurus

This planetary nebula is located right on the border of Taurus and Perseus. It is cataloged as NGC 1514 and is also known as the Crystal Ball Nebula. Even this 14-minute exposure shows a lot of details in the nebulosity. The magnitude, depending on the source, is listed at 10.9.

Tech Specs: This image is composed of 56 x 15 second images at ISO 5,000 with 5 x 15 second darks and 5 x 1/4000 second bias frames using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Imaging was done on November 6, 2016 from Weatherly, Pennsylvania.

The Hickson 93 Galaxy Group in Pegasus

The Hickson 93 Galaxy Group, also referred to as Arp 99, can be found in the constellation Pegasus. From the Atlas of Compact Groups of Galaxies (1993), Paul Hickson stated, “This group (Arp 99) consists of an accordant quartet plus a fainter high-redshift galaxy. The bright spiral galaxy has two long plumes which result from tidal interaction. It is a radio and infrared source. The bright elliptical galaxy is also a radio source.”

This grouping is about 265 million light years away, five main galaxies are shown in the image, but only four are thought to be gravitationally bound and strongly interacting. You can see in the image how NGC 7549 is distorted by gravity, slowly pulling away strings of stars and gas.

The particulars on the galaxies shown are:

  • NGC 7549, magnitude 13.8, barred spiral galaxy.
  • NGC 7550, magnitude 13.6, lenticular galaxy.
  • NGC 7547, magnitude 14.7, barred spiral galaxy.
  • NGC 7553, magnitude 15.3, elliptical galaxy.
  • NGC 7558, magnitude 16.0, spiral galaxy.

Tech Specs: This image is composed of 192 x 15 second images at ISO 5,000 with 10 x 15 second darks and 10 x 1/4000 second bias frames using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Imaging was done on November 6, 2016 and November 22, 2016 from Weatherly, Pennsylvania.

NGC 6804 – Planetary Nebula in the Constellation Aquila

This wonderful little planetary nebula is found in the constellation Aquila and clearly shows an inner and outer halo when processed. It is about 4,200 light-years away and has a magnitude of 12.0 with a 14.4 magnitude central star.

The image center is located at RA (hms): 20h 22m 22.776s and Dec (dms): +20° 05′ 55.485″ with an image size of 38.6 x 31.6 arc-minutes. North is to the right.

Tech Specs: This image is composed of 96 x 15 second images at ISO 5,000 with 5 x 15 second darks and 5 x 1/4000 second bias frames using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Imaging was done on November 6, 2016 and October 10, 2016 from Weatherly, Pennsylvania.
