M42 + Running Man

[johnnyt123]

Hi all...

Here is my second attempt at imaging M42 and running man.
Seeing was fair

Used:
William Optics ED Doublet110mm Megrez (no focal reducer used)
Heq5 Pro
Celestron Autoguider
Orion Starshoot Deep sky imager colour CCD camera

This is a composition of the following exposures:
20x 10sec
20x 30sec
20x 40sec
10x 100sec
No dark, flat or bias frames used. (still learning)

stacked in Deep Sky Stacker and processed in CS6

Hope you enjoy

Nice shot Johnny, a little too 'black' on the background, but still a pleasing image.

That's because it is clipped in the black. Great data otherwise. Just due for a quick repro. :thumbsup:

I think it looks beautiful. Much better than my attempt!

[johnnyt123]

Yeah I agree the black is too dark.
Over did the levels ....

I would love to have a look at your shot Lauren...

Here is the same set of data

this time however I took it easy on the processing

That looks a lot better. Flat fielding next will get rid of uneven illumination. Meanwhile you can us a gradient removal tool to flaten the field. Many programs do that.

The original was very nice, but the repro even better. Nice work, Johnny

You really need to watch the histogram. The background should never be truly, noise is real - it's okay to keep it in. :lol:

Great work, inspiring for a beginner like me. :thumbsup:

Thanks Marc, Laurie, Cam, Gavin

Marc I am still trying to get my head as to how to take flats,darks and bias frames.

The last set of dark frames I spent hours taking were all rejected by DSS. ..
Is there s good article to rea that explains the difference and more importantly for to take all these frames?

I would look through the project and articles section on the home page here as there are a number of articles written about those exact topics.
