Teapot of Sagittarius

Here is a view of the teapot section of Sagittarius taken early this morning, May 8, 2017.  This is about as high as it will get in the skies of Carbon County, Pennsylvania.  Looking forward to capturing some nice deep space objects later this year.

Tech Specs: Canon 6D, Canon EF70-200mm f/2.8L USM lens, ISO 3200, 3 x 8 seconds, f/2.8, 70mm, tripod mounted. Date: May 8, 2017. Location: Weatherly, Pennsylvania.

On a side note, this is my first attempt at manual stacking in Photoshop.

Messier 70 – Globular Cluster in the Constellation Sagittarius

Globular Cluster Messier 70 (M70 or NGC 6681) is a globular cluster that can be found in the constellation Sagittarius, it is about 29,300 light years away and close to the galactic center. Focus shifted a bit on this one, but I’m still adding it to my Messier list until I can image this again.

Tech Specs: This image is composed of 32 x 15 second images at ISO 3200 with additional dark and bias frames. Meade LX90 12” telescope, Antares Focal Reducer, and Canon 6D camera. Imaging was done on August 30, 2016.

NGC 6717 (Palomar 9) – Globular Cluster in Sagittarius

NGC 6717 is a globular cluster in the constellation Sagittarius hidden right next to the supergiant star Nu2 Sagittarii. It has a magnitude of 9.3 and represents a good challenge for your telescope. This cluster also bears the name Palomar 9, most of the Palomar globular clusters were discovered in the 1950’s using photographic plates from the first Palomar Observatory Sky Survey (POSS).
