HI all,
Here a quick shot of the centre of the eagle nebula.
10 x 90 sec
H-Alpha filter
10" SCT.
Homebuild CCD cam cooled to -14degr.
the sky wasn't that clear (lot of moisture which makes the stars bigger).
Will try again with more transparent sky.
Processing was done in Maxim and CS3
thanks for looking,
