TerryMcK Posted June 15, 2021 Share Posted June 15, 2021 Excellent. I’ll try this one out when I get back to the computer. Thanks for the heads up Brian. Quote Link to comment Share on other sites More sharing options...

I'm just watching the second video now Terry. From what I gather, this script will eliminate the need to use SubFrameSelector from your workflow. It works in conjunction with Image Integration, and stacks the images based on SnR, as well as a few other things too, concerning gradients and star size. It looks a great addition to PI. 1 Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted June 16, 2021 Share Posted June 16, 2021 What version have you got Brian? Mine shows up as version 1.0 but in Adam's videos it is showing up as V1.1 - I've tried doing a PI update but appear to be at the PI current release.

AstronomyUkraine Posted June 16, 2021 Author Share Posted June 16, 2021 I only have version 1.0 Terry. Someone mentioned this in the comments section on the 2nd video in the series. It seems Adam has a beta release, this is his reply. "Yes...sorry, I should have mentioned I am just a bit ahead of the release here. Everything I show will obviously be in the next update of the script." In Adam's version there is an image integration section at the bottom of the script which is missing on v1.0 1 Quote Link to comment Share on other sites More sharing options...
AstronomyUkraine Posted June 16, 2021 Author Share Posted June 16, 2021 (edited) Just had a quick play with the new NSG script, and I'm impressed with the results. The top image is a SHO combination using my normal workflow, stacking the individual filter frames using the SSWEIGHT keyword in ImageIntegration. The second image is the result of the 3 SHO filters using files generated by the NSG script. I think the results speak for themselves, the second image using the new script has definitely brought out more detail and nebula from the background, especially on the left hand side of the image. Also the gradient on the second image has been evened out considerably. Both images were combined in ChannelCombination and stretched using STF and HistogramTransformation. No DBE was applied.

AstronomyUkraine Posted June 16, 2021 Author Share Posted June 16, 2021 (edited) The next version of the script will have an imageintegration tab incorporated into the script, and it will autopopulate the files created into Imageintegration with all the correct settings automatically selected. Until then, here is the settings for integrating the files produced by the script. Notice, no Normalization is selected in both Image Integration and Pixel Rejection (1). The keyword is NWEIGHT.

TerryMcK Posted June 16, 2021 Share Posted June 16, 2021 I think I may buy Adam's PixInsight fundamentals plan after seeing some of his tutorials. It seems well worth the $180 oneoff fee. 1 Quote Link to comment Share on other sites More sharing options...

I believe they are really indepth tutorials, and those he posts on Youtube are the simplified versions of his videos. Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted June 16, 2021 Share Posted June 16, 2021 It would be interesting to contrast Adam's tutorials with those I have paid for from MastersOfPixInsight.com run by Warren Keller and Ron Brecher who are also esteemed teachers of PI. Those virtual workshops cost $35US a go and I have paid for 8 now. All of those were live 2 hours over GoToMeeting (a bit like Zoom) and recorded for those who were not able to make the sessions. They can be bought subsequently too and are available for viewing in perpetuity. I found them extremely good full of great info and downloadable resources Quote Link to comment Share on other sites More sharing options...

Altogether there is a collection of 180 videos in the fundamentals course, and it is ever expanding, so £1 a video seems a good deal to me. 1 Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted June 16, 2021 Share Posted June 16, 2021 I think Adam's tutorials are a winner then in that case. 1 Quote Link to comment Share on other sites More sharing options...

I have found the latest beta of the script and it's near to the bottom of this page https://pixinsight.com/forum/index.php?threads/normalizescalegradient-1-1-beta3-available.16507/page-5 I've tried it out and it has the integration option. The good thing is you can have the beta and the released version 1.0 in the scripts pulldown at the same time. I unzipped it into the scripts folder and renamed the folder containing the script by appending beta on the end. You can then either disable the original script or fire up either of them (not at the same time of course LOL) Quote Link to comment Share on other sites More sharing options...

I just stacked some Ha frames using the new script v1.0. The advantage of the beta version it autopopulates the frames and settings in Imageintegration automatically.

MarkAR Posted June 18, 2021 Share Posted June 18, 2021 Certainly looks impressive. Will try it out soon on my Bodes & Cigar data. I blinked all the images and nearly everyone looked fine, ran image selection and just on FWHM it showed a dozen not fit to use. From the looks of it you calibrate (using WBPP) with no normalisation and don't integrate either, run the calibrated files through the script then integrate. 1 Quote Link to comment Share on other sites More sharing options...

Although you can do everything "by hand" for more control. The latter makes my head hurt though 😆 1 Quote Link to comment Share on other sites More sharing options...

From what I have heard a few people say, is to choose the image with the highest altitude as your reference. I can see the logic of that, as theoretically it will have less rubbish in it, but if they are taken a couple of hours either side of a pier flip, it will make no difference IMO. I just load up SubFrameSelector and choose the image with most stars or SNR, as my reference for the script. I also noticed yesterday on the PI forum where @TerryMcK pointed me to, for the v1.1 update, one of the PI guys involved in this script, recommended only using it on galaxies and nebula, and use SubFrameSelector on star clusters and globular clusters. 1 Quote Link to comment Share on other sites More sharing options...

So far the results in NB are not much different than if I use SubFrameSelector, but seeing as this script is targetting gradients, BB and OSC will certainly benefit.

Brian Yep Brian, I think OSC will greatly benefit and make processing a lot easier. I have only tried it with LRGB so far, but will keep it in my arsenal for tricky NB gradients.
