About this image

This is my first serious use of the ZWO 294MC CMOS camera for deep sky imaging; my usual camera is a QSI 683. So this is very much an answer to my question, "How does a CMOS camera work?". Answer, "Very well, indeed".

I was prompted to try this target after an online outreach session using the camera with Sharpcap. I was curious to see what the camera would produce and how I would then combine images taken at different exposures to produce a single high dynamic range image. The exposures were 4 sec, 30 sec and 120 sec. I needed to do quite a lot of work to separately process the images and then to combine and finish them. I don't have the aperture to resolve the fainter Trapezium stars but nevertheless, I'm pleased with the result.
