Mars in February 2012

Mars is coming closer to opposition (first week of March). Its disc increased to over 12″, making it an easier astrophotography target.

On the 4th of February, the seeing was pretty good. Visually, at 400x or so,  Mars disc was quite stable and full of details.

With a focal length of 7,000mm (using a barlow 2.5x), each pixel on the DMK covers about 0.15″.

On the right you can compare with a simulation of Mars disc captured on Calsky.org.

    Hi Chris – Thanks! For the Infrared picture I used about 1,000 images – and for the LRGB 1000 images for Luminance, and 500 images for each channel. I used registax 6 and kept about 80% of the frames…
