Although image quality is not perfect, I am glad to share here my first images of deep sky objects. It's a difficult effort to capture the light of such distant celestial objects, the method is known as "prime focus photography".

Hi Paschalis...
I assume your 'scope is f/10... were you using a focal reducer/field flattener, or were these at full effective focal length?
Have you tried stacking multiple exposures?

Yes, focal reducer was used as well. I know that stacking multiple exposures results to superb images, but I don't know the steps. I have only applied "dark frame subtraction", contrast, a little neat-image.
... Images were taken from a location close to a beach.
