Mars 18th April IR-RGB
Mars 18th April IR-RGB

The IR742 is a near infra-red filter that only passes light with a wavelength greater that 742nanometres through. The atmosphere refracts the shorter wavelengths (which causes the sky to appear blue), so filtering everything but the near infra-red provides the sharpest images. You can clearly see how the IR and Red channels contain the most detail with the blue being badly distorted. I use the Red, Green and Blue data sets to provide colour and the IR data set overlayed to provide detail.

This image is taken with a mono camera and RGB filters. The data is then combined to produce a colour image. A luminance layer is created using the Red data as this enhances the detail in the image. Captured February 2014

Imaging Io is a tricky problem as Io moves at 17kms per second, which means that it moves its own diameter every 3 minutes. I have captured the bright yellow colour of Io (from its constant covering of sulphur and sulphur dioxide). The moon has smeared a little due to its fast orbital speed.

Jupiter Ganymede & Callisto

Ganymede is the largest moon in the Solar System and is nearly the size of a small planet (it's three-quarters of the size of Mars). I am very pleased to have captured some detail on the moons, as imaging a 5200Km target at 633 million Kms is certainly a challenge!
