The first album cover below shows a Saturn image and two spectra which include a reflectance spectral curve of Saturn's atmosphere and another of Saturn's rings; I divided each of my originally recorded spectral curves by a spectral curve for a Type G2V star to adjust for the effect of our Sun's spectrum (which is a Type G2V star). I captured the planet's image on Aug 5 2014 using a spectroscopic diffraction grating connected to my telescope's camera to generate a visible light spectrum for Saturn's atmosphere and rings. This type of spectroscopic analysis reveals the presence of methane (CH4) in Saturn's atmosphere and hydrogen in Saturn's rings using only data present in light captured by my telescope and camera.
Note the red spectral curve for Saturn's atmosphere and green spectral curve for Saturn's rings. Also note the bottom of this color slide where I show two visible light spectra in bar form; the top bar is the spectrum for Saturn's atmosphere and the bottom bar is the spectrum for Saturn's rings; note the thick black line in the top bar at around 6190 Angstrom wavelength that indicates the presence of methane in Saturn's atmosphere due to absorption of photons at this wavelength by the methane molecules in the atmosphere.
Notice that there is no methane absorption peak in the ring spectral curve like the peak at around 6190 Angstroms in the atmospheric curve.
I captured this image with a C11 SCT, a Canon 550D DSLR camera and a spectroscopic diffraction grating known as the Star Analyser 100.
I created this spectral graph with a program called Rspec (Version 1.7). If you'd like to do this kind of spectroscopy please visit the website for Rspec and the Star Analyser 100 to find out how to get started: http://www.rspec-astro.com/
Please click on any of the album cover images below to reach the entire collection of images for the planet or moon shown. For example clicking on the Jupiter album cover takes one to 3 separate collections of images captured between 2010 and 2014. Clicking on the 2012-2013 collection of images opens up every image I've taken of Jupiter between August 30 2012 and May 1 2013. Each of these images may be clicked on to reach a larger version of the image together with a more detailed description.
