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 and very young stars in NGC 3372, the Carina Nebula
Results are presented of a large-scale imaging photometric study of the stellar population in the northern part of NGC 3372 with a wavelength coverage from 0.33 to 2.5 μ m. All observations were made at Las Campanas Observatory. The sizes of the three stellar clusters, Tr 14, Tr 15 and Tr 16, were determined by means of star counts. Two-colour andTapia, M. et al.
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. deg.Burgess, A. S. M. et al.
