Photographer's Note

I took this image of Moon with a 7 inch Quester Telescope. I didn't use a tripod ..I just hold it in my hand after eyepiece..an shoot it.
It was my first astronomical image with my digital camera..since the exposure time was long..and my hands were shaking...so all the images were
either out of focus or blurred..only a few out of nearly 250 images were sharply focused. After this I took many more images of moon , Saturn and
Jupiter. May be I will upload all of them in near future.
In this image all the Mares are identified with the help of NASA solar atlas..If any one is interested, then please write to me..I will send you the same image with the name written in proper places.
The difficult part of astronomical imaging is that the incoming light signal is poor (for moon it is not the case) for other planets..so
you must give a very long exposer. On the other hand the digital camera also produces some noise when it is heated..( other source of
noise are atmospheric turbulence, cosmic ray, light in big buildings etc).
as a result the image may contain appreciable amount of noise..and then
it is very difficult to bring real image out of this. A whole new subject
called 'Astronomical Image Processing' has come up..they mainly deal
with this noise elimination technique. One good book in this field is written by Richard Berry.

Finally I would like to request you to see the Planets through the eyes of telescope..it is a fascinating experience.
