Comet 17P/Holmes - This photo is a V (green) image of Comet 17P/Holmes taken at LBTO on 6-November-2007 by J. Hill, A. Rakich and D. Gonzalez Huerta. The exposure time was 10 seconds with the LBC-Blue prime focus camera. This JPEG image was created from the raw FITS file, so boundaries between the CCD chips are still visible. |
| Messier 81 - Messier 81 is a bright spiral galaxy (type Sb) in the constellation of Ursa Major. This false color image is created from very deep LBT prime focus images taken with LBC-Blue in the B (blue) and V (yellow) bands. The integration time is of order an hour per filter since the M81 field was observed several dozen times as part of a program during Science Demonstration Time in Spring 2007 to measure Cepheids and other variables in the M81 field. M81 lies at a distance of 12 million lightyears from earth. Note the faint dwarf galaxy Holmberg IX in the upper left of the image.

Holmberg IX (UGC5336) - is a dwarf irregular galaxy which is a faint companion of the bright spiral galaxy M81. Holmberg IX is a young dwarf galaxy (age about 200 million years) that was may have formed during a recent tidal interaction between M81 and NGC 2976. This false color image is created from very deep LBT prime focus images taken with LBC-Blue in the B (blue) and V (yellow) bands. The integration time is of order an hour per filter since the M81 field was observed several dozen times as part of a program during Science Demonstration Time in Spring 2007 to measure Cepheids and other variables. Holmberg IX lies at a distance of approximately 12 million lightyears from earth. The Cepheid measurements will soon refine this distance estimate.

Messier 1 - This color image of Messier 1, the Crab Nebula, was taken at the Large Binocular Telescope during November 2006 by Vincenzo Testa and collaborators from Rome Observatory. The image is a true-color composite composed of separate images in red, green and blue light obtained by the 36 megapixel Large Binocular Camera at the prime focus of the left 8.4m primary mirror. The Crab Nebula is the remnant of a supernova explosion in the constellation of Taurus which was observed in the year 1054. The Crab Nebula is located in our own Milky Way galaxy at a distance of about 6300 light years from Earth. This data was taken during commissioning tests of the camera in advance of scientific observations in spring 2007.

Messier 31 -- Andromeda Galaxy This single 900 second near-ultraviolet exposure of the center of M31 was taken during commissioning of the LBC-Blue prime focus camera in December 2006. This image shows the central region of one of our nearest neighbor galaxies -- the great spiral in Andromeda. The image unveils the near-ultraviolet view of the inner ring of star formation recently discovered by the Sptizer Space Telescope, and shows in great detail the fine structure of the dust lanes associated with the galaxy's inner spiral arms. The capabilities of the LBC-Blue camera are probed by direct comparison with GALEX satellite observations of the same central region of M31. The image on the left (click on thumbnail) compares the LBC U image with the bluer GALEX NUV image. The image on the right (click on thumbnail) compares the LBC U image with the Spitzer 24-micron mid-infrared image. Photometry of this image has identified 6 new candidate globular clusters, and has confirmed a number of previously known candidates from the Revised Bologna Catalogue of M31 globular clusters.

These LBC images taken at LBT during the commissioning of the blue prime focus camera show the famous gravitationally-lensed arc in cluster of galaxies CL2244-02. The massive cluster in the foreground at redshift 0.3 bends the light of a distant blue galaxy in the background at redshift 2.2 to make the spectacular arc(s) seen in the images. LBT observed this field in through 4 different filters, so the images here are an RVB true-color view and a VBU false color view to emphasize the effects of star formation at blue wavelengths.

Abell 576 -- This image is a psuedo-color composite of the nearby
cluster of galaxies Abell 576. The image was taken at LBT with the
LBC-Blue camera at prime focus during science commissioning in Fall
2006. Abell 576 lies relatively close by at redshift 0.039 (540
million light years). Most of the several hundred bright galaxies
seen in this image are members of the cluster. From redshifts of the
individual galaxies and from X-ray satellite observations we know that
the cluster is an on-going merger of two smaller clusters.

Abell 611 - This image is a psuedo-color composite of the distant cluster of galaxies Abell 611. The image taken with the LBC-Blue camera at prime focus is composed of a near-ultraviolet, a green and a red image. The blue arcs near the center are gravitationally lensed images of distant background galaxies. The mostly yellow galaxies are members of the Abell 611 cluster which is doing the lensing. The image is about 2 arcminutes on a side, North is up, East is to the left. The integration times were 20 min in Uspec, 60min in g', and 15min in r'. The image quality in the combined images is about 0.6 arcsec FWHM in g' and r', but they were smoothed to match the 0.7 arcsec image quality of the Uspec observation. These data were taken during March 2007 as part of a weak lensing program in the LBT Science Demonstration Time. The color composite image is courtesy of Paul Martini of Ohio State University. |

NGC 4736 - This deep image of the Seyfert galaxy Messier 94 (NGC 4736) was taken in V-band (yellow) light with the LBC-Blue prime focus camera at LBT. This image was obtained as part of observations obtained during Science Demonstration Time observing in February 2007 by observers N. Bouche, P. Buschkamp, P. Smith and O. Kuhn. A total of ten 164-second dithered exposures were taken. This stacked image (combination of the ten individual images) was provided by Dennis Zaritsky of Steward Observatory who leads the team studying a sample of galaxies similar to M94. These images will be used to understand the full extent of galaxies. In particular, these images can be used to identify regions of star formation well beyond the main optical disk that can then be used to measure the mass and angular momentum of the outermost baryons. In turn, these measurements tell us about the angular momentum of the dark matter halo of the galaxy and about angular momentum transfer during the formation of the inner disk. |

A near-ultraviolet image (left) from the LBC-Blue observations in the outskirts of galaxy M94 is compare to a far-ultraviolet image (right) from the GALEX satellite. By comparing and contrasting the images at different wavelengths, astronomers are able to study regions of star formation in this galaxy (measuring the light from hot, young stars).

NGC 6946 - This color image of the face-on spiral galaxy, NGC 6946, was taken at LBT on 18 September 2006. NGC 6946 lies at a distance of about 16 million light years from earth. The false-color composite was made from images taken through near-ultraviolet, blue, and green filters, using one primary mirror and one Large Binocular Camera (blue optimized). The total exposure times were 560 secs in U (near ultraviolet), and 400 secs each in B (blue) and V (green), comprised of a stack of 20-second exposures, taken so as not to saturate the brighter stars. The U, B, V images are displayed in the 3-color composite as blue, green and red respectively. The image quality shows that commissioning is proceeding as well, with the telescope tracking and camera interfaces approaching the reliability needed for routine scientific observing.
