Orion Nebula, M43 and NGC 1977 by octane2 Orion Nebula, M43 and NGC 1977 by octane2
Full view for maximum effect

The Orion Nebula (M42), de Mairan's Nebula (M43), and The Running Man Nebula (NGC 1977)

I thought I'd share the image with you to show the potential of this magnificent new 5" refractor. This is only 30 minutes of data. I hope to build upon it when this region is culminating later in the year.

For 30 minutes of exposure, I think I've done well to tame any noise. Yes, I can see the satellite trails -- I didn't have enough data to perform a proper/aggressive data rejection stack and couldn't be bothered with cloning it out. This is a test image. Not up to my usual standards, I know -- I'm a perfectionist. Couldn't help but share this.

Look forward to a spectacular rendition later in the year.

I have a long while to go before I exhaust a DSLR imaging device.

I will spare the detailed write-up for this composition until I have something worthy of presenting. However, I will list the notable objects here.

The Orion Nebula (M42);
de Mairan's Nebula (M43) -- the little circular shaped object towards the bottom left of the main nebula;
The Running Man Nebula (NGC 1977) -- the cluster towards the left enshrined in blue and red nebulosity

This composite consists of one set of images; one set of 6 images taken at ISO-400.
Each individual image was a 300 second exposure.
IRIS was used to calibrate each image (dark subtraction [median combined master dark] and flat field division [median combined master flat {lights and darks}]), to register, align, stack, white balance, and stretch.
Photoshop CS3 was used to adjust levels, curves, saturation, colour balance, local contrast, sharpen, miscellaneous editing, frame and resize the final composite.

Wow, such beautiful colours here. Amazing detail and clarity.

I myst say I envy the use of a 25" telescope, that must have been an incredible experience.

I still remember seeing Saturn for the first time through a 130mm NR 'scope. Still one of the most beautiful things I've ever seen. I can't imagine what it would look like through a 25" :D

Other wordly, literally is though. Do you need an expensive telescope to do this kind of photography?

This is a beautiful shot. I don't see these imperfections you do, like the satellite trails... I guess you are the one with the eye for that type of thing ;P

Silvery--Sky,

Thank you for the kind words.

Watch this space. This was just a test image. I hope to gather many hours of data on this region and will produce a much nicer image.

Regards,
H
