General / Re: Sharpening with MLT and deconvolution feedback
« on: 2019 March 18 22:59:32 »
if you look at the areas inside the grey boxes, you can see some "worms" - bright, linear, slightly bulbous structures that are not present in the original image.

i think you may be able to avoid this simply by masking those lower SNR areas a little better. they do seem to be present in all of your different experiments - i have usually only seen them as deconvolution artifacts but i suppose they can be caused by any sort of sharpening.

when you bought pixinsight, you should have received an email with a username and password. this is the username and password you used to log into dist.pixinsight.com to download the app for the first time. those are the credentials you need to activate a copy of PI.

General / Re: Which image unsaved?
« on: 2019 March 16 22:31:49 »
if you have saved the project (and saved every workspace in that project) then nothing will be lost. if you re-open the project the state of PI will be exactly as it was when you saved the project.

generally speaking the "dirty/clean" logic in PI is very conservative. it doesn't count having saved a project as saving an individual file (though the image and all of its history *is* saved in the project). furthermore if you load process icons from disk, then close PI, it complains that the process icon set is modified and will be lost... yes, with respect to a blank desktop, the process icons have been modified, but even if you have not added one or changed one, you'll get this message when you quit PI.

as to your question, i'm not sure there is a way to see which files have been modified but not saved.

see FAQ 2.7. basically you should only need to copy the license file from one machine to another once you have done the activation.

anything relevant in the console log? any errors?

is it possible the PSF image ended up on another workspace somehow?

General / Re: White circular patch on the stars

if the local support image is not working to your satisfaction you can also mask the cores of the stars with a regular old starmask...

yes it tends to saturate the cores. what deconvolution is doing is concentrating the energy of the star more toward the center, since in essence it is trying to undo the blurring in in the image.

you might try a local support image for Deconvolution. this problem is common around stars. or, maybe make your mask stronger so the stars are not affected as much by the deconvolution process.

General / Re: "Pure RAW" or "Demosaiced RGB"?
« on: 2019 March 11 10:25:31 »
yes if you tick "Pure Raw" then you need to tick "CFA Images" as well. "CFA Images" is telling BPP that it needs to debayer after calibration.

CFA stands for Color Filter Array and is a synonym for Bayer Array.

General / Re: Improving PI speed
« on: 2019 March 10 17:31:37 »
well the benchmark itself i think predates all the multithreading work that juan put into staralignment, so maybe the benchmark does not accurately reflect the mix of IO and computation that a pure staralignment run represents.

in this post, juan notes that for multithreaded i/o workloads windows seems to beat osx and linux, so i guess that is consistent with your findings:

General / Re: StarAlignement, before or after DBE ?
« on: 2019 March 09 09:40:26 »
just FYI DBE does not work with ImageContainer - only ABE does.

while what adam says is true if you have severe light pollution gradients what you are proposing could work, as the gradient will be clearly visible in each sub. however since you are going to apply ABE with the same parameters to each image, depending on the gradients, those parameters may not be applicable to each subframe, and you may end up under- or over- subtracting the gradient. i'd say it's more of an advanced, desperate technique and it's better to first try what adam proposes.

you should upload the files (the masters and a light) so someone can take a look / reproduce the problem.

it used to be that dell shipped some utilities preinstalled that utilized Qt, and the DLLs that were pre-existing on the machine conflicted with the PI Qt DLLs, leading to some serious problems.

i don't know if this is the case anymore on windows 10.

i think juan uses a plain-vanilla W10 environment straight from microsoft, rather than any OEM version of the OS. so that's probably the best way to ensure compatibility.
