The advantages of using a telescope of large aperture, like the GTC, for mid-infrared imaging are demonstrated. Examples are given to compare the characteristics of the images in the 8 to 13 μ m regime recently taken with the 2.1 m telescope at San Pedro Mártir with those obtained with a 10 meter class telescope. Finally, 10μ m images of the BN/KL

Young T-dwarf candidates in IC 348
Context: The determination of the lower-end of the initial mass function (IMF) provides strong constraints on star formation theories. Aims: We report here on a search for isolated planetary-mass objects in the 3 Myr-old star-forming region IC 348. Methods: Deep, narrowband CH4off and CH4on images were obtained with CFHT/WIRCam over 0.11 sq. degBurgess, A. S. M. et al.
