Description

With the raining season approaching it is very difficult to image the objects of summer, among them M-42. That is why I took advantage of this little chance the weather gave me and did this capture of M-42 using a wideband filtering system.

The subs were somewhat short in order to be possible to finish the job in one single night, because M-42 was rising late and and the Sun was rising early, besides the forecast for the next day had been cloudy with some rain.

Luminance:

6 x 30sec bin 1x1

8 x 60sec bin 1x1

12 x 300sec bin 1x1

RGB

8 x 300sec subs of each channel

Bias, Darks and Flats applied.

With the luminance frames I built a HDR image to preserve the details of the Trapezium, although the ideal would be to have complete LRGB images to do so.

The scope used was a TMB 92mm f/5.5 and the camera a ST8300M.

Pre-processing and processing in Pixinsight.
