Dear Friends,
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.
Full resolution image here (http://cdn.astrobin.com/images/f96b0a95-ef2f-464c-8156-660d4ab65af1_hd.jpg)
Despite to be a commonplace image, I hope you like it.
Thanks for looking,
Fernando
