Star Analyser 100 - First Light (Wide-Field)

Some wide-field spectrographs in the dark sky, before the near full Moon had risen too far and completely washed out the background.

 

Canon 760D with Sigma 70-300mm APO DG lens and Star Analyser 100 diffraction grating.

 

Vega: fl 70mm f/4 ISO 3200 2.5s

Mars: fl 70mm f/4 ISO 3200 2.5s

Moon: fl 70mm f/4 ISO 3200 1/4000s

Cassiopeia: fl 70mm f/4 ISO 3200 2.5s

 

Basically processed using PS Express - cropping, black level, contrast, luminance noise.
