DESCRIPTION: http://en.wikipedia.org/wiki/North_America_Nebula TECHNICAL NOTES: This is a single 121 seconds exposure with an unmodified Nikon d3100 DSLR camera. It has been taken under light pollution WITHOUT any LPS filter. Note the wonderful star colors although the nebula hasn't been taken out due to the IR block filter of the cam. EQUIPMENT: Telescope: 385mm (f/3.65) Guider: SBIG ST7XME on a 355mm (f/6) scope. Mount: JPZ Software: Aperture v3.1.2 (Mac). Only histogram adaptions has been one in the NEF (raw) file.

Nikon d3100 with AF-S DX VR Nikkor 55-300mm ISO 100 220mm f5.6 1/320s. CAUTION: To avoid any damage, the use of a Baader Astrosolar foil in front of the camera lens is mandatory!
NGC7000
DESCRIPTION: http://en.wikipedia.org/wiki/North_America_Nebula TECHNICAL NOTES: This is a single 121 seconds exposure with an unmodified Nikon d3100 DSLR camera. It has been taken under light pollution WITHOUT any LPS filter. Note the wonderful star colors. The nebula has been taken out using the Tone Mapping Technique, since the original filter of this cam is optimized or daylight and it blocks the red channel. EQUIPMENT: Telescope: 385mm (f/3.65) Guider: SBIG ST7XME on a 355mm (f/6) scope. Mount: JPZ Software: Aperture v3.1.2 (Mac). Only histogram adaptions has been one in the NEF (raw) file.
The stars around the Veil Nebula
DESCRIPTION: http://en.wikipedia.org/wiki/Veil_Nebula TECHNICAL NOTES: This is a single 138 seconds exposure with an unmodified Nikon d3100 DSLR camera at ISO400. It has been taken under light pollution WITHOUT any LPS filter. Note the wonderful star colors although the nebula hasn't been taken out due to the IR block filter of the cam. EQUIPMENT: Telescope: 385mm (f/3.65) Guider: SBIG ST7XME on a 355mm (f/6) scope. Mount: JPZ Software: Aperture v3.1.2 (Mac). Only histogram adaptions has been one in the NEF (raw) file.

The Sun with spots
Nikon d3100 on a Mewlon 210 using the dedicated Tak f/9.3 reducer. Due to the long focal length (1961mm) of the scope, the Quiet mode, high ISO rates and short exposure times were mandatory to reduce the vibration issues caused by the camera mirror.
