2MASS LGA Data Atlas
You can get a close-up map of a region by selecting a point in red on the above image, or by typing a coordinate below.
The 2MASS Large Galaxy Atlas (LGA) is a collection of custom-made mosaics and additional data products for 649 extended objects, mostly galaxies. This image atlas represents the first uniform, all-sky, view of galaxies as seen in the near-infrared (2MASS JHKs) wavelength windows that are most sensitive to the dominant stellar mass component of galaxies. The images allow close inspection of diverse stellar populations, large-scale structures such as spirals, bulges, warps and bars, and star formation regions of galaxies.

LGA images are also available by clicking on a red region on the IRAS galactic image above or by typing in coordinates or an object in the search window below. Also available are LGA image "cutouts" using IRSA's Cutouts Service.
