IC 1805 and Melotte 15 Wide Field – Photographed Using a Hydrogen-Alpha Emission Line Filter

This wide field image of the emission nebula IC 1805 includes the open cluster NGC 1027 (far left-center), the open cluster Melotte 15 (center) and the emission nebula NGC 896 (upper right).  NGC 896 is also known as IC 1795.  The emission nebula IC 1805 and NGC 896 and the open cluster Melotte 15  are believed to be about 7,500 light years distant.  The large and bright stars of Melotte 15 are believed to be the primary illuminating source of the IC 1805 nebula.

This image was taken under the clear dark skies at Anza-Borrego Desert State Park in San Diego County, California on September 27, 2018 with a Takahashi FSQ-106EDX IV astrograph using a Takahashi f/3 reducer.  The camera was a ZWO ASI1600MM-Cooled with an attached ZWO EFW2 filter wheel and a Baader 36 mm unmounted 7 nm bandpass hydrogen-alpha filter.  The final image is a compilation of 45 x 240 second exposures which were calibrated, aligned and integrated using PixInsight.  Image enhancements were performed using PixInsight and Photoshop CC.
