About this image

Only 2-hours of integration between clouds and on a night of a full moon.  The Optolong LeNhance filter is a narrow band filter passing only Ha and Oiii with the QHY 268C one-shot-colour camera.  Camera in 'High Gain' mode with gain set at 56.  Hopefully, I will be able to collect some more data on this fascinating nebula, named the Cave Nebula by Patrick Moore.

All image calibration, integration and processing with PixInsight.
