Jupiter and Oval BA – Red Spot Jr.

Here is an image I took from March 24, 2017 distilled from a video and processed in Registax. It is the first time I have been able to identify the feature referred to as Oval BA, also known as Red Spot Jr. The image on the right was taken by the Hubble Space Telescope on April 3, 2017 for comparison, you can more clearly see this cloud feature in the HST image.

From NASA, “Oval BA first appeared in the year 2000 when three smaller spots collided and merged. Using Hubble and other telescopes, astronomers watched with great interest. A similar merger centuries ago may have created the original Great Red Spot, a storm twice as wide as our planet and at least 300 years old.” (Source: https://science.nasa.gov/science-news/science-at-nasa/2006/02mar_redjr)

I look forward to continue learning planetary image processing and collecting additional video streams.

Tech Specs: Video captured using Meade LX90 12” telescope and ZWO ASI290MC camera. Imaging was done on March 24, 2017 from Weatherly, Pennsylvania. Software included AutoStakkert! V2.3.0.21, Registax v6 and Sharpcap v2.9.

Messier 109 – A Barred Spiral Galaxy in Ursa Major

Messier 109 is a barred spiral galaxy located in the constellation Ursa Major, it is about 84 million light-years away it has a magnitude of 10.6.

Tech Specs: This image is composed of 50 x 60 second images at ISO 3,200 with 5 x 60 second darks and 5 x 1/4000 second bias frames using a using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount (ASI290MC and Canon 400mm lens for guiding).  Imaging was done on March 23, 2017 from Weatherly, Pennsylvania.

This 20-minute wide-field view was taken on March 22, 2017 using a Canon 6D, Canon EF 400mm f/5.6L USM, and an iOtron ZEQ25GT mount. 120×10 at ISO800 and f/5.6.

A Crescent Moon and Mercury in the West

Last night offered a nice view of the conjunction of the young crescent moon and the planet Mercury in the western skies of the Northern Latitudes.  Mars was also visible, although higher above the moon. You can see some stars of the constellation Cetus just to the right of the moon. The ½ second exposure was just enough to bring out the Earthshine on the moon.

Tech Specs: Canon 6D, Canon EF70-200mm f/2.8L USM lens, tripod mounted. ½ second exposure at ISO 640, f/2.8, 140mm. Imaging was done on March 29, 2017 from Weatherly, Pennsylvania.

Here is an updated version after I had the time to make some adjustments.

The Sunflower Galaxy – Messier 63

Here is a view of the Sunflower Galaxy, Messier 63 (M63) found in the constellation Canes Venatici. It is a spiral galaxy surrounded by many short spiral arm segments. It is also a member of a group of galaxies referred to as the M51 Group. The Sunflower Galaxy lies roughly 37 million light years from Earth and has an apparent magnitude of 9.3.

Tech Specs: This image is composed of 42 x 60 second images at ISO 3,200 with 5 x 60 second darks and 5 x 1/4000 second bias frames using a using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount (ASI290MC and Canon 400mm lens for guiding). Imaging was done on March 23, 2017 from Weatherly, Pennsylvania.

Comet 41P/Tuttle-Giacobini-Kresak in Ursa Major

Here is a view of Comet 41P/Tuttle-Giacobini-Kresak taken last evening, March 22, 2017 as it passed near the Messier objects called M97 (a planetary nebula) and M108 (galaxy).

Tech Specs: Canon 6D and Canon EF 400mm f/5.6L USM lens mounted on an iOptron ZEQ25GT mount. 22 x 120 second exposures at ISO 800 and stacked using the comet mode in DeepSkyStacker.
