Messier 13 – Globular Cluster in Hercules

Certainly not the first time I have imaged this huge globular cluster, nor will it be my last. This is the first test of the new pier setup in my observatory. It is hard to believe that there are over 300,000 stars in this cluster! Quick six-minute total exposure.

Tech Specs: Meade 12” LX90, Celestron CGEM-DX mount, 400mm guiding lens, Antares Focal Reducer, ASI290MC guide camera, Canon 6D, 6 x 60 seconds at ISO 3200. Captured with Backyard EOS and stacked in DeepSkyStacker.

Sagittarius Teapot Over Seneca Rocks, WV

I recently had the opportunity to spend a few nights in the Seneca Rocks area of West Virginia. After 36-hours of non-stop rain, I was stunned by the crystal clear dark skies in this area! I think they rival the dark skies that I observed in Wyoming and Montana. The light wispy clouds add some depth to this image showing the teapot section of the constellation Sagittarius. Unfortunately, I was only equipped with a stationary tripod on this outing, but I’ll be back.

How many Messier objects can you find in this image? You can see the open clusters M6 and M7 just getting ready to go behind the trees in the lower right.

Tech Specs: Canon 6D, Canon EF70-200mm f/2.8L USM lens, tripod mounted, 10 seconds, 70mm, ISO 3200, star filter added for some diffraction spikes. Location: Seneca Rocks, West Virginia. Date: July 30, 2017.

Hope you like it!

Andromeda Galaxy System

Having not had a lot of telescope time during the summer months, I find myself reprocessing data collected in the past. This is a reprocessing of the Andromeda Galaxy region including insets of the two brightest satellite galaxies, M110 and M32. This is from data collected from 2015-2016. The wide-field view was collected using a Canon 6D and 400mm lens, the inset images were captured with my Meade 12” LX90 telescope.

Messier 108 – The Surfboard Galaxy

Messier 108 (M108), nicknamed the Surfboard Galaxy, is a barred spiral galaxy located in the constellation Ursa Major. The galaxy lies at an approximate distance of 45.9 million light years from Earth and has an apparent magnitude of 10.7.

Tech Specs: This image is composed of 27 x 60 second images at ISO 3,200 with 5 x 60 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. Guided using a Canon 400mm lens and ZWO ASI290MC camera. Imaging was done on February 26, 2017 from Weatherly, Pennsylvania.
