I love this hobby. At every turn, you think you have reached the limits of your equipment, you then realise you can improve your own techniques.
See asto deep sky photo forum, for my results after using the correct software... Deep sky stacker is tops!! It will take pride of place on the desktop next to Registax.
Edit~ That's got to be one of the all time NOOB moments.... Using the wrong program, I must have spent literally 6 hours on all attempts until asking here...
On a side note, don't anyone get me confused,
REGISTAX is the most awesome program ever!!! This was entirely my fault.
