2MASS Equatorial South Pole Mosaic: 2MASS Equatorial South Pole Mosaic (257 KB) and Coverage Map (94 KB):
A 10x compression of a 2MASS K-band south pole mosaic. Both images are shown with a loglog stretch. You can see the gradation in noise in the mosaic towards the edges, as opposed to the center which is covered by nearly 300 different 2MASS images.

Near the Galactic Plane (1.2 MB): A three-color mosaic derived from images in the Second Incremental Data Release of the 2 Micron All Sky Survey (2MASS). This picture shows dust clouds and nebulosity in the plane of our Galaxy, and it combines images at three near-infrared bands. The mosaic contains 12,000 individual pixels on a side. There are 347 individual images in each of three bands: J (1.25 µm), H (1.65 µm), and K (2.2 µm). This image has been reduced to roughly 1/24 of full resolution. Contact montage@ipac.caltech.edu if you are interested in a higher-resolution version.

Sloan Digital Sky Survey (495KB): A JPEG image built from three of the five bands of the Sloan Digital Sky Survey (SDSS), centered at Dec 0.0, RA 10h 40m. Red is the G filter, Green is the R, and Blue is the I filter. The image is about half a degree in size: 1800x1800 pixels at 1" per pixel, made with 7 images in each band. The color image was made by reducing each output pixel from eight bytes to one (from the 30 percentile to the 99.9 percentile) and applying a square-root contrast filter. The center of the image is on the equator at RA 10h 40m. This image was built on a 6-cpu Teragrid Itanium machine.

Rho Oph and the Galactic Plane (362KB): We see the bright band of the Milky Way Galaxy spanning the bottom of this image, with the Rho Ophiuchi dust cloud floating above. This large swath of infrared sky is 60 degrees in width, and the blue, green, and red colors correspond to the 12, 60, and 100 micron bands observed by the Infrared Astronomical Satellite (IRAS).This image was created for the Cool Cosmos site by Robert Hurt.

GLIMPSE Validation Object: G305 (4700 KB): 1x1 degree field of view centered on 305.3 +0.2. This is a 3-color combination using 2MASS J (blue) and H (green) bands, as well as MSX (red). To see more GLIMPSE mosaics created using Montage, go here.

Andromeda (584KB): This image is an full resolution (1.5 arcminute pixels) mosaic of the 60 micron IRAS image (ISSA) data. It covers a 60 degree square region of the sky centered on the Andromeda Galaxy (Messier 031) and was generated in Galactic coordinates (the Galactic plane runs across the top of the image. The image is actually 2400 pixels square and has been resampled down here by a factor of three.

Orion (216KB): This region is just south of the Galactic plane in a direction almost exactly opposite the Galactic center. Since in that direction we are nestled up against the inside edged of a spiral arm, the various clouds of dust and gas and associated star-forming regions are spread out more than in other directions (where we see them at a greater distance).

This plane of the galaxy runs across the top of the image and the active area below that coincides with the visible constellation of Orion (his head is in the general vicinity of the ring of brightish emission on the right and his belt runs through the very bright area on the left).

The original ISSA plates that went into making up this image are outlined in gray. The image, comprised of 31 images covering an area 45 degrees across, took 9072 seconds to process on a 300 MHz Sun UltraSPARC-IIi.

Rho Ophiuchus (237KB): Rho Ophiuchus, 45 degrees wide in Galactic coordinates. The Galactic center is bottom center of the image. Processing of the 32 original images took 9677 seconds on a 300 MHz Sun UltraSPARC-IIi.
