EIGA Data Atlas
You can get a close-up map of a region by clicking on any area in red on the above image, or by typing a coordinate below.
The Extended IRAS Galaxy Atlas (EIGA) is an extension of the original IRAS Galaxy Atlas (IGA) to more northerly galactic latitudes. High resolution images at 60 µm and 100 µm have been produced to match the latitude coverage of radio continuum observations obtained as part of the Canadian Galactic Plane Survey (CGPS). Also associated with the EIGA and IGA is the Mid-Infrared Galaxy Atlas (MIGA).
Also available are EIGA image "cutouts" using IRSA's Cutouts Service, which is a general tool to create single or multiple small FITS (and JPEGs) image cutouts of datasets archived at IRSA.

EIGA images are represented as overlays in red on the ISSA all-sky composite image above. Either type in a coordinate or click on any red region to get a close-up of the area; the size of the search is adjustable.
