Pixinsight Processing Walkthrough - M51 - Start to Finish
« on: 09:46:32, 20 October, 2013 »
I have had a couple of requests to do a screen cap video of my image processing workflow in Pixinsight. Hats off to people who have done several of these, its a lot harder than you think so excuse the Ums and Ers and the fact that I refer to M51 as a nebula on a couple of occasions.

This
is a start to finish video using some OSC frames I took earlier this year so the workflow is equally usable for DSLR images (If using DSLR images in PI be sure to go to the DSLR RAW format and change so that DSLR RAW images come into PI as RAW monochrome images with no Black Point Correction). It covers all the major processes I typically use

Sub Frame Sorting and Selection
Image Calibration
Cosmetic Correction
Debayer
Star Alignment
Image Integration
Colour Calibration
Dynamic Background Extraction
Non-Linear Stretch
Wavelets
Histogram Equalisation
Saturation Boosts
Star Masks
Star Reduction



The video is shot in 720HD but takes a bit of time to feed from YouTube as HD. Total run time is 53 minutes and I have time warped the few processes that take a lot of time.

Chris,
Thank you for taking the time to put this together.  :big_clap

I looked at pixinsight a couple of years ago when Phil mentioned it but talked myself out of getting it. Since PSP2013 i have again been looking at this software and the many videos about it.
I think i may put my auto focuser on hold a couple of months and bite the bullet with a purchase of pixinsight  :D

This talkthrough will serve as a great starting point for me getting to grips with the software.  :yes:

Paul....

There are also some cracking tutorials from Harry Page - look them up on uTube...

(Well done Chris... nice dulcet tones there :clap: )

Cheers Chris,

I watched this but have had to send you a PM regarding the audio @ 33:16 it just goes,  but you have covered the bits that will start majority of anyone wanting to start.

 Got a request.  Since I'm a total noob at PI, (can't even figure out how to crop an image lol), can you guys post some useful links here or in some other stickie?  Like also the Harry Page links which I can't find to save my life (I'm in the US, dunno if that makes a diff).

 One of the things I see in your video Chris is how you have a window on the bottom where you can select all the different stretch functions.  For the life of me I can't figure that one out either.

 And yes, I am a SLOW pupil lol.

Take a butch here https://www.dropbox.com/sh/l9y64ye1u8qhuh9/Tg7z3b380C where I have done a load of .pdfs including some imaging examples.

Harry's most excellent video tutorials (with the most wonder narrative voice) are here http://www.harrysastroshed.com

The window at the bottom of the screen is called a ScreenTransferFunction (under IntensityTransformations) and is just what the title suggest, a screen stretch so you can see what is going on with linear data. Pixinsight allows and intact favours doing some things on linear data (colour calibration/background modelling/deconvolution etc) so the STF allows you to monitor progress.

Chris

ps. Stick with it. Its very different from an other user interface but after a while it does make a lot of sense and becomes very second nature.

 Much obliged Chris!   :urock: :urock: :urock:

 Lightbulb just went on and managed to find the screen transfer function window.  Yay, now I ca actually do one thing!  And if I learn one more thing I'll be twice as smart!  :laugh:

 Oh and I downloaded all your stuff and will read before visiting Harry's page.  :)

 There's hope for me yet!

Excellent video Chris - really useful and easy to follow - thank you very much. I have used my free 45 day trial period of PI and am convinced its for me and with yours, and Harry's tutorials, its not quite so daunting.

Steve...

Good choice.... the best thing I have found over the past year or 2 with PixInsight is... you can use as much or as little of it as you want... and after the initial large barrier, you can then add workload as you go along.... basic calibrate, register/stack, DBE, histogram stretch, curves & you have a really good 1st pass completed... often much better than hours of messing about elsewhere...

Rarely have I ever said money well spent... & I have been in I.T professionally > 25 yrs!

There are some excellent and possibly unique tools in PI (like DBE for example) that I use when needed, but for standard processing without 'difficult' problems to solve I now prefer StarTools. Its more simple interface belies the underlying image processing power it posesses, and it does not require the rigid workflow of PI. There are a few weaknesses but overall it can cope with 95% of my processing needs, the other 5% is taken care of with PI and Ps. Perhaps as I become more adept at image processing I'll rely more heavily on PI but for now StarTools is my favourite.

I've had a go at Startools but my meagre Sony Vaio 64bit 2GHZ 4GB RAM cannot handle the processing load put on it !!  PI managed no problem - Startools comes to a grinding halt.

I know this is an old thread but I am replying for two reasons.

Firstly to thank the OP for taking the time and trouble to make the tutorial and for sharing his no doubt hard won knowledge. I am coming to the end of my free trial with PI and was on the point of giving up and certainly way beyond ripping my hair out and screaming. Now I can do 'things' and am making rapid progress! So a very big thank you !!!!!

Secondly to make this excellent resource more obvious in the search results !!!

Thanks You Chris Bailey !!!!
