"In my experience there's no such thing as luck" - Obi-Wan Kenobi

 

I don't care for the term "lucky imaging" I prefer to call it the brute force approach. This was the result of video captures one second exposures with FireCapture and the ASI1600MM. 500 frames each filter I used 300 frames for Luminance & Red & 150 for Green & blue. I split them into individual images, applied darks, and auto aligned & stacked with Nebulosity. I did two stacks with an without darks and noticed there was an improvement in eliminating banding noise so the effort was worthwhile. I ended up not using much of the luminosity layer the red channel data proved to be more useful for that. Processed in PixInsight & Photoshop CC.

Beautiful. I did a very similar image in Halpha with 0.1sec exposures with the ASI1600MM last week. Wish I'd done full colour now!

This image looks flat and dull lacking contrast. It gives the impression that there is a lot of dust overlying the bright inner region, but the dust lanes and clouds are indistinct and not very well defined. I think the image has a lot more work needed.

Great job!! You don’t see many images that show the E & F stars so clearly let alone the other background stars that you were able to capture.

Joe R....

 

I want to join the group that is giving you a thumbs up on this image....

 

Don't know where HarryRik9 is "coming from"... but i guess we all have our own opinions.

So Harry... i will be anxiously awaiting your posting of your image (different thread of course) showing better contrast, and definition !!

 

I have imaged this target many times, and i understand how difficult it is to get the "trap" is display all of its stars...

Not an easy task!  Not at all.

 

Well done Joe R.

Anyone who has tried to image the trapezium knows how difficult it is to completely resolve the E and F stars and to completely bring out G, H1, H2 and I in the same image. This one is very beautifully and skillfully done, and your typical snarky aesthetic remarks demonstrate very clearly how little you understand of the challenge.

My apologies to everyone else for rising to the bait, but some things needs to be said.

Hi Tim,

 

I totally agree with you. It is the second time I read such a comment from the same person. Looks like he has a monitor adjustment problem as I explained before and he seems not to be able to resolve it. It is the best resolution image I have seen from the Orion Nebula center.

 

There is a lot of detail in the dust clouds and his comment

 

lot of dust overlying the bright inner region

seems to confirm a too bright monitor. I understand that as if he sees it through an milky acrylic glass sheet and for me that is sign of wrong monitor adjustment, but OK what can we do.

Thanks guys through the eyepiece I can easily resolve stars E & F with my C14 much better than all my previous optics. I wasn't even aware of stars G H1 & H2 until I attempted this target. We had strong winds from the nor'easter come through here just before so it must have cleared out the atmosphere pollutants and gave me a nice clear window.

Harry appears dull and lacks interest. He gives the impression of having a lot of dust between his ears, knowing only how to snipe and criticise yet apparently lacking any skill or positive attributes himself.

 

I think the man needs a hug.

Congrats! That's a really great photo and is one of few I've seen of the trapezium that brings out some of the detail I've seen visually of the region on nights with excellent seeing. Very nicely done!

Wow, that is beautifully resolved, great image!

Never have obtained such a good focus as you show here,

great job!

Very hard not to blow out the core and you nailed it :waytogo:
