Let;s take this one step further. Say I WBPPed a few nights and kept the calibrated files and all than. Then I add a couple of night more some time later. Is there a way to save the tiem of recalibrating the initial set of data and calibrating just the added data? Obviously measurements, LN (if applicable), registration, etc. must be done for the whole set.

I can't wait to play with this one. great job Adam!!

you sure do come up with innovative ways to exploit pix's tools Adam, bravo!

Is Drizzle check box removed in this? I can't tell if we should just check "Rejection maps / drizzle files" in Calibration? It's not clear in the documentation if that runs Drizzle, or just prepares for it

I am also having trouble adding the script to my repository. I have added the link, saved, and then ran the update. The update showed new items, which I applied and then restarted PI. But the script does not appear under Utilities. I have screen shots if they will help. I consider myself competent in this area as I have added numerous items to my PI repository.

Wonderful location and wonderful image

I don't have Pixinsight yet but I like these videos 😅 Btw how is this different than using defringing option in camera raw filter of Adobe PS? It does a surprisingly good job with just one click!

58:49 This reminds me very much of wavelet sharpening of images of Mars. There is a lower limit on size, and oversharpening causes artifacts of that size.

Amazing!

Wonderful presentation Adam!

as per usual in my world, this doesnt work for me. After selecting edit, the target keyword list is empty. and I know there are values to be listed. In my situation, I am trying to plate solve a bunch of files in a mosaic. But the focal length is wrong in the fits header. I thought if I could edit the header to the right values solving would work. Oh well. maybe theres ANOTHER way

anyone else having issues with the script download? I put the address in PI and checked for updates. It downloaded but doesnt appear anywhere to open. The site says will open under scripts> utilities it isnt there any ideas?

This video not only shows you how but also explains why. It's amazing!

LOL!

I know this is an older video, but why do you state Flat frames could have an exposure of 30 or more seconds? Seems everyone is preaching Flat frames should be just 3-4 seconds tops. HAs something changed since this video has come out?

Thanks. Great tutorial!

Where is this GAME script? I don’t have it

How do I add my flats/bias/and darks in fast integration?

Excellent as usual, Adam.

You can also blend two monochrome images. I did this to mix bin1 and bin2 masters

Would you use This Image Blend script for adding continuum subtracted Ha data to RGB?

Sorry Adam but I must have missed something. I saw in Fundamentals the whole process for developing M83. However I was quite "shocked" by the lack of calibration process. What happened to the famous dark-fdlat-bias frames? Maybe you explained it somewhere?

why don't you use oneshot color image for reference only.

Why did you not background neutralize this one?

One thing I find striking is the improvement in sharpness of the ImageBlend result compared to the LRGBCombination. It looks like your L image is sharper than the RGB, so is LRGBCombination not adequately retaining that level of detail in the result?? I thought that was the whole point of the tool!

Adam, you are solving my biggest gripe so far, regarding LRGB imaging. I avoided taking L-s for the reason that producing an LRGB image was a 50-50 chance turning out good or bad. Eventually I find it to be a waste of time, because I buried the L with the curves and it did nothing to the image. I'm gonna try this method ASAP! Thanks again!

I’ve just been using the color and luminous blend mode in Photoshop, which has been really effective, but curious about trying it this way

Interesting new tool Adam, and certainly one to try out. However, a bit underwhelmed by the comparison between the LRGB color channel combination method and the script. One thing that the script rather clearly demonstrates is that there is a need to ensure some form of DBE/gradient removal be done and that color image be color corrected (as would be a normal process) before proceeding to the 'stretch' and subsequent steps. If the component images have garbage, that seems to be ehanced in the combination process. The LRGB color combination image seemed to show an increase in black level and some reduction of the color bias/gradient relative to the script created image (at least as was visible in the KZbin video). How does the script tool work with starless images created with tools like SXT? I normally separate the stars out and work with them separately from the object (except when the object is a globular cluster or something similar). That allows the freedom do work with colors/saturation/contrast without impacting the star color or creating 'bloom'. How does it react when the Lum layer is also used as a mask to prevent changing/impacting the background during the combination process? I like that the tool provides a means to preview the result, something the LRGB channel combination tool lacks. At first glance that seems to be the biggest single benefit, since the LRGB CC tool requires trial and error to get things 'just right'.

What is going on here? Was something in Pixinsight made EASIER to use?? I really don't understand how this can happen. It runs counter to the entire product philosophy behind Pixinsight!! I may have to delete my installation of it!

Very nice. Thank you

Thanks for this free public teaser! I just watched the entire series in Fundamentals on your website this weekend, and got a lot out of it - highly recommended!

Amazing work. Looking forward to trying the script on my data.

That's cool. I bet this would work well for Ha, LRGB images.

Hi Adam, I'm very near the end of the Fundamentals path. There's a recurring question that I've never had answered satisfactorily: If you've shot enough RGB that color noise in your target is well controlled then why do you need L? Your SNR is, by definition, already high so what's the benefit? I often see images where L is used to bring out faint details more quickly and the overall structure looks fine. The color, however, is usually mottled or smeared, presumably from insufficient RGB. It appears that the color data gets heavily processed to control noise with tools like Blurxterminator or with convolution. While this can look ok superficially it doesn't look very good under even casual closer inspection. Is there something I'm missing? Thanks!

This is so awesome. Can I do this with blending lumens from mono with OSC data?

Nice! When in the process do you integrate them? At the start or after first processing both the luminance and rgb?

Hi Adam with OSC do you extract a luminance image from the RGB image?

Thanks Adam!

looks great! is LRGB combination (native pix version) supposed to be a non-linear process? I've always used it in the linear stage with linearfitted, calibrated and background neutralised images, which would give me a very flat result that I'd manipulate further in processing. This is because I have quite a practiced and developed RGB processing workflow, and I feel more comfortable with using the regular Pix tools for my non-linear processes (curves, masked brightness adjustments etc.). With your tool, would I be able to still do the L+RGB combination in a linear state, not a non-linear one as you showed in the video, so that I can stretch and process them together?

Adam provide to us, without any doubts, the best tutorials about image processing wordlwide, from over twenty years (and many of them are free).The investiment in your tutorials are the best expense that an amateur can afford. Thanks a lot, for your time and creativity.

Thanks for being so amazing Adam!

Perfect this is what I m looking for LRGB was always difficult for me to combine try different methods thank you Adam for your work greetings from switzerland

Amazing Adam! This script is most welcome! Thank you

Oh wow I can't remember what I did on this date but you did something incredible, thank you

That fireball is bonus. The ISS went through a couple of my frames, which I thought was pretty kool.

Like all your images, this one turned out wonderfully well.

What a beautiful video. How exciting this must have been for you to see. Thanks for sharing.

I will continue to state how unprepared I was for just how extensive this storm was at 37° N. I remember seeing aurora as a child and it was a reddish sky with some rays toward the north. This is what I was expecting. I was completely taken aback by the display. There were curtains, pickets, blobs, corona aurora… The display extend toward the Southern Sky. Utterly amazing and emotionally evocative.
