Description

M17 Swan Nebula in narrowband Ha and OIII

Telescope:  AP 110 GTX with F5 TCC
Mount:  AP Mach 2 encoder mount unguided
Camera: ZWO 6200MM Pro
Filters:  ZWO 7nm Ha, OIII
Color Palette:  HOO

Exposure:  Ha 9 x 300 sec, OIII 6 x 300 sec
Seeing;  2 arc sec FWHM, with medium transparency, high humidity

Notes:  Local light pollution levels have increased with high brightness LED lights on the industrial property next door to our observatory.  This resulted in heavy gradients in the OIII channel and washed out the fainter parts of the OIII signal. Needs a 3nm filter. LED light doesn't seem to affect the Ha channel.
