Description

This is a purely narrowband deep integration of M42. I think it looks remarkably different than the traditional RGB images. The SII data really adds some differentiation to the nebula body from the Ha gas surrounds the region.

I'm quite impressed by the dynamic range capabilities of the QHY600 sensor. This image is composed of entirely 10 minute subframes, and the sensor was able to capture quite a lot of core details and the trapezium.

Comments and critiques are greatly appreciated.

Hope you enjoy and Happy New Year!
