Description

acquired on July 18 (L) and September 2, 2013 (RGB). The RGB frames of July could not be used due to a too low signal (not binned and fogging of the lens during the might).

The B frames were acquired high in the sky followed by G and last R. Seeing must have changed during the night and on the G and R stars were much larger. Even after size reduction they did not completely aligned with the B ones.

For me this was the 1st time shooting data at 2 different night. I found it very difficult to aligning the RGB with the L at the telescope. As this was far from perfect I had to crop a lot resulting in this picture.
