Instruments: Takahashi FSQ106ED @f/5 530mm focal length with ONAG XT (http://www.innovationsforesight.com/), Optec Gemini Focuser-Rotator, Apogee Alta F16M + 7 positions filter wheel @-25°C and Astrodon narrowband H-alpha and Astrodon broadband RGB filters on 10micron GM2000 HPS II

Softwares: SkySurveyor for MaximDL as orchestrator - MaximDL for guiding and capture - SharpLock to keep the optical train perfectly focused - CCDStack to calibrate, register, normalize, data reject and combine - Registar and PixInsight for mosaic assembly - Photoshop CC and PixInsight for LRGB composition and multiscale non-linear streching - Photoshop and APF-R for sharpening http://www.cedic.at/apfr/. APF-R does not do only sharpening it allows to reveal hidden structures that are embedded in the signal.
