Emission Nebula Sharpless 2-199 and Open Cluster IC 1848 Using a Hydrogen Alpha Emission Line Filter

This wide field view nicely frames the emission nebula Sharpless 2-199 and the open cluster IC 1848.  The emission nebula Sharpless 2-199 consists of two large evacuated bowls of hydrogen gas which were created and are illuminated by the open clusters Collinder 33 and 34 on the left side and IC 1848 on the right side.   The Sharpless 2-199 nebula and its associated open clusters are about 6,500 light years away and is about 100 light years wide.

This image was taken on October 24, 2018 from the Anza-Borrego Desert State Park in San Diego County, California using a Takahashi FSQ-106 EDX IV using the dedicated f/3 reducer.  The camera was teh ZWO ASI1600MM-C with the EFW-2 filter wheel and a Baader 8 nm bandpass hydrogen alpha filter.  Eighty subexposures of 240 seconds were captured to create this image.  PixInsight was used to calibrate, align and stack the subexposures.  PixInsight and Photoshop CC were used for post calibration processing.
