Imaging Jupiter on May 20, 2017

My Meade telescope was setup in the driveway imaging Jupiter (brightest object in the background) on the evening of May 20, 2017 and I took the opportunity to capture a wide-field view.

Tech Specs: Canon 6D and Lensbaby Circular Fisheye 5.8mm f/3.5 lens, tripod mounted, 13 second exposure at ISO 3200, f/3.5 and 5.8mm. Location: Weatherly, Pennsylvania. Photographed on May 20, 2017.

Bootes, Arcturus and a Meteor

Tech Specs: Canon 6D and Canon EF 17-40mm f/4L USM lens, tripod mounted, 20 second exposures at ISO 3200, f/4 and 17mm. Location: Weatherly, Pennsylvania. Photographed on May 20, 2017.

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.
