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:

Water Tank Run Falls in Tioga County, Pennsylvania

We ran into some bikers from Washington D.C. who were camped out just downstream of this nice cascade waterfall. They bypassed a packed overnight stop in favor of this location and had it all to themselves, they did well. This waterfall is located on Water Tank Run in Tioga County, Pennsylvania, there may be additional falls above this one, but did not venture further upstream.

Tech Specs: Canon 6D and Canon EF 17-40mm f/4L USM lens, tripod mounted, ½ and 2 ½ second exposures at ISO 100, f/18 and 17mm. Photographed on April 29, 2017.

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.

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.
