Assesment of Basic Image
This is the initial basic image, and I have not altered anything including contrast/brightness. I took measurements of the pixel counts of various locations.
Typical Pixel Counts
This image has fairly good image quality and sharpness considering the problems we had with the guiding camera not working. The noise level in the background sky seems to be typical of an image that would be taken with our equipment.
Comparison With DSS Image
The above images are of M51. The images on the left was taken by the Digital Sky Survey, and the one on the right is our image of M51 collected at the Glenlea Obervatory. It is clear to see that the DSS image has much more clarity and you are able to see more detail throughout the image. In the DSS image you can clearly see the core of the galaxy, and some beautiful detail in the spiral arms. The detector wavelength used on the DSS images shows very good resolution of the detail in the galaxy. Both images have the same shape, and it is clear that the images are of the same object. Our image is a good image for the quality of the equipment we have at the Glenlea Observatory. Even though our image was taken unguided, it did not seem to lessen the quality of our image. The DSS image and our images are very similar, and in the minimal time that has elapsed between them that is to be expected.
