Jupiter – May 20, 2017

Here is a view of Jupiter from last evening, May 20, 2017 seeing was better than I thought although there were some high thin clouds. This is a compiled image of 10,000 collected images. You can see “Red Spot Jr.” in the lower right section of Jupiter.

Tech Specs: Meade 12” LX-90 telescope, ASI290MC camera, Celestron CGEM-DX mount. Software included: FireCapture v2.5.10 x64, AutoStakkert! V3.0.14 (x64), Registax v6 and Adobe Lightroom. Date: May 20, 2017.  Location: Weatherly, Pennsylvania.

Jupiter – May 10, 2017

Here is a view of Jupiter from last evening, May 10, 2017 under less than favorable conditions. This is my first attempt at using the ASI camera along with a Televue 2.5x Powermate. The process looks promising if I get a night of good seeing.  I also need to do a better alignment job to capture more than 2,500 frames of data. With this magnification, my framerate has dropped down to less than 40 fps.

Tech Specs: Meade 12” LX-90 telescope, ASI290MC camera, Televue 2.5x Powermate, Celestron CGEM-DX mount. Software included: FireCapture v2.5.10 x64, AutoStakkert! V3.0.14 (x64), Registax v6 and Adobe Lightroom. Date: May 10, 2017.  Location: Weatherly, Pennsylvania.

Here is my FireCapture log file showing the settings:

Jupiter Animations

Here are a few animations of Jupiter for the last several evening, very addicting. The first animation, from May 3, 2017 shows the moon Io about to pass behind the gas giant.

Here is another little animated GIF file showing about 30 minutes of rotation of the planet Jupiter taken on April 26, 2017.

More on processing in later blog posts.

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.

Jupiter and Spica – April 26, 2017

Beautiful Jupiter and Spica rising over my backyard trees which are still struggling to push out spring leaves. Captured last evening while I was imaging Jupiter with my Meade telescope.

Tech Specs: Canon 6D, Canon EF70-200mm f/2.8L USM lens, ISO 3200, 8 seconds, f/2.8, 70mm, tripod mounted. Date: April 26, 2017. Location: Weatherly, Pennsylvania.
