M95 and Quasar
Dear RAC, MSRO user Marshall Faintich requested time on the MSRO 2 telescope recently to image M 95 in Leo. Enclosed is an "LRGB" image made using the photometric RB and V bands to simulate red, blue and green channels in the color composite. The luminance band was made by exposing with no filter in place. This image is about 3.5 hours of exposure time. Marshall pointed out to me the distant quasar J104335.9+115129 not far from the galaxy. This quasar is over 6.8 billion light years away! This has to be one of the farthest objects images at MSRO. Quasars are the intensely bright nuclei of very distant galaxies and on exposures with large telescopes look like fuzzy bluish stars. Careful inspection shows the bluish color in this image. Myron |
