First of all, I would like to greet everyone ‘Happy 2013 National Astronomy Week’! Night Sky in Focus was launched 2 years ago, during the country’s national astronomy week celebration.

Today marks the 2nd year anniversary of Night Sky in Focus
, a web site dedicated primarily to astrophotography, do-it-yourself astronomy, visual observation, and equipment modification. Night Sky in Focus
means two things: (1) ‘ focusing our attention to the night sky’, and in a more literal sense in astrophotography, (2) ‘focusing, on the camera’s viewfinder, the astronomical objects’ in the night sky. For more information about this web site, click here
This is my first attempt to image Saturn this season. Imaging Saturn will be more favorable in the months to come as it nears its closest approach to Earth on April 2013.

Jupiter (November 30, 2012) under better seeing conditions, taken through eyepiece projection method using a 4 inch f/9 refractor, a 5 mm eyepiece, and a Logitech 4000 web camera. Better seeing (steadiness of the atmosphere) allows imaging at a higher image scale (greater magnification) and helps resolve more details. Photo Credit: Anthony Urbano.

Image of Jupiter taken on November 22, 2012 at around 11 midnight through eyepiece projection with a 4-in f/9 refractor, a 25 mm eyepiece, and a Logitech 4000 web camera, Manila, Philippines. Image-processing done in IRIS. Jupiter’s cloud bands and the great red spot are visible in this photo. This is my best Jupiter photo to date. Photo Credit: Anthony Urbano.

IRIS is an image-processing freeware that can be used for almost any astronomical target including planets and deep-sky objects. Its command-line interface that looks very similar to DOS (disk-operating system) allows users to control almost ever aspect of the processing techniques applied to the image. I’m starting to like it now that I’ve used it several times and have seen pretty amazing results. Shown above is a reprocessed Jupiter image using the same image data in my previous Jupiter post.
