M17 Narrow band

[Paul Haese]

I thought this image deserved its own thread. Last night I picked up nearly 3 hours of SII and so I put together the data today. Certainly very happy with the outcome, which has a very 3D effect and misty look around the nebula. The outer parts of the image have a little bit of noise but the main object looks quite smooth to my eye and that is what I am looking to achieve in all my images. The whole object is fascinating to image in narrowband. Certainly glad I persisted with the use of my current filters and it goes to show what you can achieve with a 4" refractor.

Click here for the larger image (it is really cool to look at as a 100% crop).

Beautiful. I think that palette really suits it. Seems to handle the dynamic range in this object better than the regular RGB - and/or you've done a superb job with the processing. Nice work.

Cheers,
Cam

Lovely image, Paul!

[RickS (Rick)]

That turned out very nicely, Paul!

[TimberLand (Justin)]

You summed it up well with"really cool" I agree with that.

I like the diffraction spikes I take it they are an addition.

[Spookyer (Brett)]

Yep, big image is nice

[Paul Haese]

Thanks guys, appreciate you leaving a comment.

Justin, no the spikes are a product of the microlensing on the 8300 sensor. I would never add those deliberately.

Really? wow, I thought you were adding them too, they appear very pronounced, look ok though \

Nice one Paul. NB is the best rendition on that one.

Yeah really. I have no idea why they appear like that. I am told it is the microlensing but it could also be a combination of that and the imaging train itself. I definitely do not add them.

Great detail with depth.

A very good photo Paul.

Excellent with the added data now Paul. It really lifts the image up a notch one two and good data just gets better.

[Paul Haese]

Thanks guys.

Allan, I have been doing more and more now that I can go remote from home. In reality I could do with another 10 or 15 hours of data across the board here.

[Paul Haese]

For those interested I have just loaded up an image which does not have a magenta cast in the brighter blue stars. I was not happy with the stars and seem to have this more to my liking now. Use the top link to see the final outcome. Nebula is less mustard now too.

No must be the QSI somehow. I use FLI ML8300 and don't recall seeing diffraction spikes. My Proline 16803 puts in a single diffraction spike at 2 o'clock on bright stars. Some sort of internal reflection I guess.

Great image Paul.

The spikes are normal for the 8300 with microlens ... sometimes is good to see.

All the best,
Leo
