well done, orestis.
Okay, it's not as good as many others posted on this and other forums, but who cares! It proves what you can do with a basic setup, and work on this first image to get better.
Registax will process a planetary image which moves across the field of view without using any form of tracking, so that could be your next goal! I would also advise that you do try the adapter that Carl has suggested.
Keep posting your progress!
