 This is an improved version of my submission to the Self Portrait Without People III

More exposures stacked, more signal and less noise... this is with a few words the meaning of multiple exposures.
In this version, I noted just the most significant Deep Sky Objects.

- Camera : Canon 1000Da (modified for astrophotography)
- Focal Length : 175mm
- Exposures : a) 32 x 135 sec at f2.8 and ISO 1600
- FOV : 88.3%

- Alignment, calibration, stacking with DeepSkyStacker
- Further processing with PixInsight LE, PS CS3 and Neat Image.
