Trifid repro

[vlazg]

Nothing much happening up here, too hot, too many storms, so i am working on processing and trying to improve with Pixinsight. So much to learn but its coming on slowly.
Repro Trifid taken in July - LRGB

Looks really nice George with some lovely detail :)

Seems to show a few processing and/or compression artefacts there George but the colour looks pretty spot on to me :thumbsup:

Thanks Mike, it was compressed from 28mb to 120 kb to fit the thumbnail



Thanks Col,nowhere as ambitious as your latest though

[willik]

Very nice trifid and very good colour and detail

Thanks Martin, i am very impressed with the Moravian, how is your new one going?

[Andy01]

Thumbnail looks great George, got a high res version to share?
Cheers

Thanks Andy

Have not taken many images with the Moravian 16200 waiting for the weather to break.

Colours look good, George, but based on the Astrobin version it looks you've gone a little overboard with the noise reduction and smoothed away some detail.

Cheers,
Rick.

Thanks Rick, there are no peers up here so everything i do is from reading, trial and error and posts like yours. Could i make a luminance from the original rgb to bring back detail?
I have since posted a revised version on Astrobin

Hi George,

You could certainly use the colour from the current version and combine a reprocessed luminance with it.

Do you save your projects in PI? If not, it's a good habit to get into. Then you can go back to a previous version and try something different when you decide you're not completely happy with the end result (something I do all the time!)

If you don't have a project but kept the original integration files (another thing I find helpful when I do a repro a year or two later) you could build a new "super" luminance from the original L, R, G & B. Use ImageIntegration to do an average combine of these 4 integration files with no rejection.

Hope that helps...

Cheers,
Rick.

Thanks Rick, it helps a lot. I do save projects and all data anyway, I've posted a revised version on Astrobin, see post below, but only a lum from previous data, i will try your "super" luminance.
Many thanks for your input. :thanx:

[RickS]

No problem, George.

If you have good quality colour data then combining it into the luminance will give you an improvement in SNR and every littler bit helps!

Cheers,
Rick.
