Lagoon Trifid Mosaic PixInsight Version

[avandonk]

Many people have commented in the past that there was something wrong with my images. It seems I was not stretching correctly. The dark bits were too dark.

I used PixInsight to stretch this data. Two panels of the Lagoon and Trifid.

I am sure the improvement is obvious. Just goes to show we are never good enough. Always more to learn, so little time to do it in!

Excellent Bert colours look great and the contrast is not too over done, nice.

Looks good, Bert. A big improvement over previous processing I have seen from you.

Cheers,

That is a nice improvement Bert. Love the golden bath of stars in that widefield.

That's really wonderful Bert, a super image indeed! The stretch is very good for sure. I noticed that you've also got Terzan 9 in the frame - the small reddened globular near the dark dustlane in the upper right corner (here is a closeup of it (http://www.rolfolsenastrophotography.com/Astrophotography/Star-Clusters/i-CsPs9nq/A)).
So, do you find PixInsight is better, and did you follow any different steps when processing this image?

Excellent work Bert.

Here is an image at the size the data was stacked at i.e. x1.5 native pixel count. 27MB

The improvement in resolution is obvious.

The only real problem is that any 32 bit program chokes on sixteen bit images at this size!

I will try to answer any questions tomorrow.

Bert,

Interesting to do a numerical comparison on the upsized and standard resolution versions (although somewhat risky - it looks like there was some difference in processing, e.g. there is a noticeable variation in colouring).

The difference in SNR is about what theory would predict at 2.21 (1.5^2 = 2.25). The eccentricity of the stars is effectively the same (0.5428 vs 0.5427). FWHM is 4.796 pixels for the upsized version which scales down to 3.1973 pixels vs 3.745 for the standard resolution image.

Cheers,
Rick.

Looks like a good investment Bert. Stop whatever you were doing before and stick with PI - that looks to be really doing justice to another set of wonderful data.

[SimmoW]

Beautiful Bert. I'm a total beginner, still waiting for my first scope, but I've already downloaded PI and been blown away by its capabilities. Your image further convinces me that it's as important as a good camera!

Nice job Bert.

It is an impressive wide field Bert and you can only be proud of it !!!

that is a fair crack at it Bert , PI is a wonderful tool. always impressed with your data

[John Hothersall]

This is a glorious area of the sky and a splendid image, dust lanes are so sharp and defined.

Awesome, I Love this field, stunning view in your Image & has to be the best ive seen of it, , Top shelf Bert ...

[LewisM]

I was too polite before (and coming from Mr. Mediocrity himself - ME), with such wonderful data, but yes, the prior images were "odd" to use a single word.

Now... WOW! Keep going there Bert, looing GREAT!!!!

[Shiraz]

best yet Bert - that's and exceptional image by any standards. What did you do to make such a difference?

[iceman]

Stunning image, Bert. Marvellous.
The high-res version is beautiful.

It's now IOTW (http://www.iceinspace.com.au).

[dutch2]

Fantastic image, beautiful colours and detail.
:thumbsup:

Must get a handle on PI at some stage - great improvement Bert and keep them coming. Congratulations on IOTW.

Beautiful work!

Hey Bert,

Great image. I always thought the Lagoon was a bit of an ugly duckling but you've changed my mind with that lovely dusty wide field.

Cheers,
Tel

Beautiful work mate! Lagoon, Triffid and the riches of this part of the sky we will be graced with over the coming months! Congrats on your feature as image of the week. Well done :)

[alpal]

IOTW for Bert - well deserved.

[prokyon]

Stunning image, what a field. Great details and colors. :thumbsup:

[gvanhau]

I did not see the previous processing of these images, but I took a look
at the full res image.
The high contrast in the dark lanes and golden color in stars is really breath taking.

Great shot !

I was wondering what the technical details are - scope, camera etc etc.

Cheers,

Nice work Bert. Your data was always amazing but now your processing is very pretty too.

That is awesome!!! The detail of the dust in the milky way is incredible!:thumbsup:

[multiweb]

One of your best processing Bert. Congrats on the IOTW. Great field. The high-res is quite amazing. :thumbsup:
