Announcements / Re: PixInsight 1.8.6.1473 Released
« Last post by Alfredo Beltran on Today at 18:43 »
Hi Juan

I just checked and have 1.8.6.1475 version installed. However, the same SITELAT and SITELONG error is still present. Please find attached the image.

Thanks Mike - Appreciate the input.

I saw the thread during my research. Since there still seemed to be some issues with the PI instance, I decided to share the "older" standalone approach that should work for most Windows users.

I've really enjoyed using this program with my new "dual narrowband" images that are quite similar to HOO data. Sometimes the starnet++ program will degrade some of the fine detail, and, sometimes it doesn't. Just depends upon the particular target. When it works it's amazingly simple to use.

Hi Juan,

Any progress on the updates?

I've had some very nice success using the new starnet++ program to remove stars from a stretched image. The following has worked for me"

I downloaded Starnet++ from the link below which was provided by Geethq.

https://sourceforge.net/projects/starnet/

I found the following works for Windows computers:

1) After downloading, the starnet++ files will be located in a folder named starnet. Don't forget to extract the files.
2) The program only works on 16 bit unsigned .tif files.
3) Save the file you wish to remove the stars from into the starnet folder (for example, FlamingStar.tif) in 16 bit unsigned format.
4) Open the Command Prompt.
- I typed capital C in the search box in the lower left corner of the Windows 10 home screen.
- In the popup window click on Command Prompt.
- In Command Prompt type cd\the path to the starnet folder\starnet (e.g., cd\Documents\starnet ) then hit enter.
- Type starnet++ OriginalFileName.tif StarlessFileName.tif where OriginalFileName is the name of the file you want to process.
EXAMPLE: starnet++ myimage.tif mystarlessimage.tif (notice that there are spaces between starnet++, myimage.tif, and mystarlessimage.tif.
- Once the filenames are typed in hit ENTER and wait till the processing is completer. Progress is shown as %done.

When the Command Prompt says Done, the resulting starless image will be located in the starnet folder.

Attached are examples showing an original image and the starless version produced by starnet++.

Using PixInsight, I typically do sharpening (MLT), contrast enhancement (LHE), color saturation boosting with CurvesTransformation, and noise reduction (TGV) on the starless image. Your processing software and enhancement choices may be different.

Once the starless image is "enhanced" I use PixelMath to combine the starless and original image with the simple expression

max(original, starless)

Hope this makes sense.

Gallery / Globular Cluster M5 and dozens of galaxies
« Last post by Astrodoc on Today at 09:22 »
This is M5, one of my favourite globular clusters. This image also shows dozens of distant galaxies; some are shown on the included annotated image. This was the First Light image for the Eagle 3 Pro computer which controlled all the equipment. It performed flawlessly.

More equipment updates coming soon :-).

This is an excellent tool!  It takes me sometimes 3+ masks before I am happy that I have included all the stars I wanted in my stark mask.  For areas with nebulosity and small galaxies in the background (that look like stars), it is sent from heaven!  >:D
Thank you!

An interesting and well designed and implemented script. I see several potential issues for its practical application, but very nice work!

Some of these scripts deserve their inclusion in the official PixInsight distribution for sure. I don't know why this has not happened before—probably my fault. I have just invited Hartmut to join our team of collaborators at our official GitLab open-source repositories.

Hi Mät,

This is a machine-specific issue that cannot be reproduced under normal working conditions, on any supported platform. My advice when things like these happen is a performing a complete reinstall of Windows 10, trying to achieve the cleanest possible configuration without any vendor-provided utilities (bloatware).

On my secondary OS (Ubuntu) the software runs fine. However I would prefer working on Windows.

Interesting. The reference implementation of PixInsight is the Linux version, where you'll get the best performance and reliability by far. Soon we'll have a FreeBSD 1.8.6 version, which will be equally stable (if not more) and with similar performance levels.

Hi Stuart, Renan,

These are machine-specific issues that cannot be reproduced under normal working conditions. The most probable cause for these issues is the OpenGL implementation in your graphics drivers. Try running the application with the --opengl=raster command line argument. This may fix these problems, or at least alleviate them somewhat.

Why PI was working with v 1453 and after installing 1473 and also after going back to 1457 this problem exists?

There is no logical reason for this to happen on the PixInsight side. Maybe there has been a system or driver update that has created this problem. I cannot know.

Please note that Windows 7 and Windows 8.1 are not supported by current PixInsight 1.8.6 versions. The only Windows version supported officially is Windows 10.
