Hi, everyone!

 

I was made aware that threads in Vendor Announcements, which I was using to get feedback and receive help requests, should only be used for announcements, so I've decided to create a couple of threads here, in Experienced Deep Sky Imaging. Not sure how far this will go, but oh well.

 

This thread is for experience share: will be glad to hear back from you about your experience with StarNet, good or bad, examples of processed images, etc.

 

The thread to request and get help is here: https://www.cloudyni...-help-requests/

 

I will start by sharing a couple of results I get on my end:

Starnet v2 is excellent with PixInsight on my M1 Mac. This is the first version of the program I've used, and I'm delighted with the results. 

Here's NGC 6188 in narrowband from iTelescope.net's T30 (Planewave 20" CDK + FLI-PL6303E  CCD, imaged from Eastern Australia):

I'm enjoying Starnet 2, but I don't use it to produce starless images.  Starless images always look distorted, as if someone manually clone stamped the stars out.   My use of Starnet is to separate stars, stretch the nebula slightly, then rejoin the stars and continue processing.  The ability to do this while linear is fantastic.  Thanks for making this interesting software.  Any plans for Starnet 3.0 ?

I don't have examples to share, but can simply say that as nice as V1 was, V2 is 20 times better, and the ability to use it to create linear starless masters is wonderful, as I too use it to remove stars and process nebulosity separately before adding RGB stars back form other data collected at the same time. Just a wonderful job on this, really amazing work! bow.gif

I just tried out the WIndows GUI.  Works great, but how do you get the star mask?  I was under the impression that you would get that image also.

Anyone installed V2 to PI on Linux and gotten it to work? I follow the directions and PI never finds the process when I tell it to search. The libtensor* files in the lib directory didn't look like they had typical shared lib permissions, tried changing those, still no dice. The file mentioned in the troubleshooting section is in the specified spot. This looks like some requirement is not being met...

I tried earlier today, but was not able to copy the files into the PI directory due to permission issues. I don't know why they don't use a repository link so we can actually use the normal installer for this stuff.

Same here. I also used the Windows GUI but wonder how I could get the star mask with stars only.

I see many examples which show the starless object and a star mask in the Tipps & Tricks section ont he starnet website.

But there is no option in the Windows GUI to save a star mask.

 

Anyone can help out here? 

Is that possible in PI only? And if yes how to get it there?

In your favorite image editor.  Place the original photo, and the starnet output image next, then just change the layer property of the starless photo to difference, and instant star mask.

Clear Skies !!

I cannot for the life of my get this to work as a plugin on the Pixinsight linux distribution in EZ Processing Suite. I've followed all the instructions, but I'm starting to suspect that it's a file permission issue. 

 

/opt/Pixinsight/bin/ and it's child directories are only accessible with sudo. I think maybe having to get sudo access in order copy the Starnet2 files where they need to be might be somehow interfering with PI actually using it correctly. 

 

Specifically, it fails when trying to use EZ Processing Suite. EZ Decon uses Starnet2 to make a mask and it simply fails out.

 

Anyone had this issue? 

 

 

(EDIT)

 

Soooo....of course I figure it out right after posting. Every tutorial on this that I've found said to put the files from the Linux download into /opt/PixInsight/bin and /opt/PixInsight/bin/lib but never once mentioned having to set the Weights File in the original Starnet process. THAT is what Starnet2 looks for. Once I realized this, the process went a little farther before it would error out, but it still failed.

 

Then I looked for exactly where those weight files were in linux, and they were in /opt/PixInsight/library so I had the obvious idea to put the new StarNet2_weights file there. I also threw in the libtensorflow and libtensorflow_framework files that came with the StarNet++ linux download and lo and behold, EZ Processing Suite Deconvolution now works correctly. 

 

Yowza!

Hello nekitmm.

Just for your information.

In the next big release of Siril (1.2.0), it will be possible to use starnet.

I already used it in an unofficial version of siril and it works well. Very easy to use. Also with linear data. And pretty good results like the stand alone version.
With siril you need to install the command line version.
