M101

 
M-51 RGB Apr18_06 Healed web.jpg (10626 bytes) This is the Whirlpool Galaxy, M-51.  It is an excellent example of interacting galaxies.  The galaxy at the bottom is accreting stars and gas from the galaxy above.  Eventually, only one galaxy will remain.  This system is ~70,000 light years from Earth.  That means that when the light in this image left M-51, the Earth was just starting the last ice age and mastodons were still a part of the eco-culture.  

The image was taken in three colors [RGB] with one hour of exposure time in each color.  The three colored frames were then assembled in the computer to create this image.   April 2006
NGC7331.gif (24634 bytes) This image of NGC 7331 is composed of 14 x 600 sec exposure using 1x1 binning.  A   Luminance filter was used.  This galaxy is part of the Deer Lick Group.  It is a  Spiral Sb type galaxy.

M110 Averaged in AIP4Win PreMaxEnt.jpg (512447 bytes)

This elliptical galaxy is NGC 205 aka M110.  It is composed of 6 x 300 sec exposure at 1x1 binning through a Luminance filter.  Stretched

This galaxy, NGC 7217 is an 11th magnitude Sab type spiral galaxy.    The image is composed of

 
NGC91.jpg (15819 bytes) NGC 91 [the spiral galaxy in the image] is an unusual spiral galaxy in the constellation Pegasus.  There are several other galaxies nearby, which may account for its oddities.  C14 unfiltered, 30 minutes total exposure at f/11 using ST-10XE, 1x1 bin. Distance: over 200 million light years. Diameter: >60000 light years across.  [70% the size of our galaxy] 
m66_2.jpg (88332 bytes) This is my first attempt using an SBIG ST-6 CCD camera. The object is M-66. Apr. 12, 1999. C-14 at prime focus. 150 sec exposure with Lumicon Deep Sky filter and IR blocking filter. Good seeing but the sky was not particularly dark. Image is slightly over digitized using CCDOPS. Also, camera was only cooled to 20C below ambient of ~10C, so there is too low of a s/n ratio.
M-51-3.jpg (35554 bytes) M-51 taken at prime focus through a C-14 using a Lumicon Deep Sky Filter and an f6.3 reducer. This image is the sum of two guided 3 minute exposures
m88.jpg (36375 bytes) This is M-88 taken with the ST-6 using an IR filter at prime focus through a C-14. It is the sum of 10 x 30 second exposures and was processed using StellaImage. This picture was taken on June 2, 1999 just a few days after the discovery of SN1999cl. The supernova is at about the 2 o'clock position from the center of the galaxy
