Ha, which is everybody but Adam Block and a very fortunate few others. (Adam points out he still gets significant gradients even from on top of Mount Lemmon at nearly 10,000 feet).
G’day Shawn Great review of the new tool I will definitely give it a go on some old data Always great to get notifications of your latest upload As always thank you Cheers
My RASA flats cause such horrific gradients... I have finally found nearly perfect way of taking them, but there is always still some very subtle vignetting.. i really hope this script helps me out... thanks for the video!
Thanks for this easier to understand video. I also own APP and its "star analysis" assigns a score for each frame, making it easy for me to pick a RF for each channel. No doubt, the score isn't perfect, but it's no worse than me trying to pick a RF when they mostly look the same (in my more limited experience).
I will have to look into this. Cheers Shawn. I don't know if you noticed but your left image is zoomed in 1 stop more than the right. Perhaps not a 'like for like' comparison in this case?
This looks a great addition to Pixinsight. Just wondering if using the SubFrameSelector to determine the best reference frame for the Normalize Scale Gradient Script could give better results.
You could use SFS to determine the best reference frame if you like. It isn't really necessary though. Finding one in blink or using the highest altitude frame is effective.
I for sure did the update to the latest version but it’s not showing the new update under batch processing. If anyone else has a work around I would greatly appreciate it. Also watched the GAME script video and am looking forward to trying that one as well. Thanks for the great videos!
Hi Shawn, Thanks for your videos. They are very usefull to me. Do you think doing a video to talk about how to make good adquisition imagen with monocrome ccd camera anf filter weel? All my data files are no so good for making beautifull final image :-). Thanks again for your support
The way I choose my ref frame for NSG is to go to subframe selector and select the photo with lowest median, which also has a low fwhm. Do you think that make sense?
So I have to calibrate, debayer and register my subs first, right ? And I won't use subframe selector to apply weight because the script will already apply some ?
I updated pixinsight to the latest version but I don’t see this script under batch processing. Is there an additional step after updating I must do to have the script show up there?
Shouldn't be any other steps needed. I uninstalled the previous PI version, installed 1.8.8-8 and the script was there. If you're still having problems I'd ask on the PI forum.
@@stevelawrence2927 I had the same question and my understanding is that it will make the job of DBE easier but this is not instead of it. I am a little confused about when this step whould be included in the process. Is that just before normalisation ? is that just after calibration ? In the video the files seem to have only c and r so i suspect this is after calibration and subframe selector....
No. You would still use ABE or DBE. The normalized scale gradient script will apply the same scale and gradient of the reference frame to all of the images, making them consistent and thus your master will not be effected by multiple gradients compounded say. It will then make applying ABE or DBE easier/effective.

Great news for us that have to shoot from light polluted skies! Thanks so much for sharing Shawn.

Thank you for producing this ... most appreciated.
Awesome, thanks for making this video, Shawn.
Just for info - John also developed the Photometric Mosaic script which also does a sterling job. You can find it under Script/Mosic.
G’day Shawn
Great review of the new tool
I will definitely give it a go on some old data
Always great to get notifications of your latest upload
As always thank you
Cheers
Didn't realise that new script was there. Thanks for letting us know.

Thanks for another great presentation Shawn
Thanks for walking through this Shawn!
Thanks for sharing this info, Shawn! A good one to use!
Thanks for the tutorial Shawn; very helpful!
This is a Great Video Shawn! thanks..

Didn't notice at the time! That's making a video for ya. lol.
Thanks for this video. One question, as a newbie PI user: How does one run Batch Preprocessing without integrating? IE just calibrate and normalize?

I just figured it out you have to download the new Pix update from their web site directly. This will then add it.
Ha! I was going to ask you to look at this on Facebook.
HMM so what do us OSC users do when we hit this hurdle?
I am missing this script in 1.8.9-1 Ripley. Where can I find it? Has it been removed?
Kewl, I'm going to use this, I have several that I want to reprocess
Great video , thanks for all the time you put in to them , can I ask if/where NSG is for Pixinsight 1.8.9 ??
This looks good.. I should probably update, lol.

Sure. I'll put it on the list!
I have 1.8.9 as well and cannot find this script anywhere. Anyone find it in 1.8.9??

Yes. and Yes!
@@VisibledarkAstro thx!
Hi mate, when I stack osc images in WBP the final image comes out black and white.. Any ideas as to what I'm doing wrong?
I updated pixinsight to the latest version but I don’t see this script under batch processing. Is there an additional step after updating I must do to have the script show up there?
Shouldn't be any other steps needed. I uninstalled the previous PI version, installed 1.8.8-8 and the script was there. If you're still having problems I'd ask on the PI forum.
Hey Shawn, It's gone for PI now Is it redundant?
I'd just use the local normalization option in WBPP now. Does as good if not better in my testing.
Do you use this instead of ABE ???
Or DBE?

@@VisibledarkAstro i was told this was initially designed to be used for mosaic...
This video could last 3 minutes.
To long?
