July 19 2005 - M13 and M92
These Shots were taken on July 19 2005 with my 5" mak cassegrain telescope.
Image of M13. This image is composed of 23 x 10 sec exposures for an equivalent of 230 seconds at ISO 400. I chose a lesser exposure this time to minimize star trailing. Instead of using the 15 second exposures I decided to take much more 10 second exposures which will reduce the noise levels. As well a dark frame was used with these.
M13 close up - 22 x 10 sec exposures (220 sec equivelent) at ISO 400.
M92 - This is my first real image of m92. Image is composed of 10 x 10 sec exposures (100 sec equivelent) at ISO400 and dark frame used.
