The left hand image (1992) was taken with MAGIC, the MpiA General purpose near Infrared Camera. It is not cleaned in any way and shows me in reflected light at a wavelength of 1.25 micrometers (J-band).
The right hand image (2010) was taken with an engineering grade array of FourStar. It is not cleaned in any way and shows me in reflected light at a wavelength of 1.65 micrometers (H-band).

The following instruments and projects keep me busy:
