Well done in resurrecting DSS!

Hi Steve - this looks like its how AVG behaves when encountering a new never-before-seen EXE download (its signature is not in the master AVG database). Not surprising as the EXE was only created yesterday. Hopefully your sacrifice in being frisked at the security desk will stop this behaviour happening again when others with AVG attempt the download smile.gif

 

My pleasure!  I do what I can....lol.gif

I use AstroToaster (which uses the DSS stacking engine in the background) for EAA live-stacking. I did an informal test using the DSS 64-bit beta on my Win10 64-bit laptop with AstroToaster. I had no issues using the beta version with AT. I stacked 15 .fits files (32MB each) using a master flat and it took 4min 46sec to complete stacking. I then tested the same set of files using the older DSS version 334, with the same settings. It took almost twice as long, 7min 39sec. This is great news for AstroToaster users!

It will take 100x 50mp files from a Pentax 645z and register and stack with no problem or crashing in one go. Still wont do drizzle on full frame 36mp files from a Pentax k1. Regardless, it is much faster than it was. I wish there was a way to assign it more RAM

Can somebody post a DSS 32-bit vs. 64-bit processed image?

We're aware of the issue with Drizzle and are working on it.  

RAM isn't a limitation in the 64 bit version (so long as you have an adequate swap file).  I was stacking some stuff yesterday that meant i was using all 32GB of RAM and about 20GB of swap file.

"so long as you have an adequate swap file"

 

Dave, do you mean by that, that it will be better to manage swap files by user and not automatic by Windows?

 

Great news that there is new life for DSS btw!

No not really, a manually managed fixed size swap file is very marginally more efficient than automatic, but it is marginal.

What I was getting at was the situation where the swap file size was manually set to (say) 4GB, and you have 32GB of RAM and DSS wants to use 36G of memory, then it will fail!!

For the full story there's an extensive article here: https://blogs.techne...finitive-guide/

Jim,

The images should be identical.   You can install both the 32-bit and 64-bit versions on a Windows 64-bit system (they don't conflict).  So you can check this with your own stacks.

Hello all - Luc has asked me to post his message about new versions of DeepSkyStacker - specifically there is now a 64 bit version
 

 



The installers can be found here:

64 bit version - https://github.com/L...64Installer.exe
32 bit version - https://github.com/L...erInstaller.exe

 

64 bit version as a ZIP file  - https://github.com/L...64Installer.zip
32 bit version as a ZIP file - https://github.com/L...erInstaller.zip

 

(The ZIP versions are provided if your web browser blocks exe file downloads)

 

I (Tonk) will pick up any issues reported here - but Luc would prefer (if possible) for bugs to be reported on the DeepSkyStacker yahoo group - or if not possible you can also use the GitHub issues page found here - https://github.com/L...fier/DSS/issues

Regards Tonk pp Luc Coiffier

Just wanted to say that DSS 64 works like a breeze for me

...and is fast; I guess it take full advantages of all 16 cores

I tried with 190x 24Mpix and it registered and stacked in one go w/o any error

Normally it would take several run to register all frames; and maybe 1-2 trial to stack everything

Well done!

Is Luc planning to add a "donation" link to the official website?

Hello Luc and David,

 

first of all thanks for your work and effort. I use DSS for about two years now.

I downloaded x64 version today.

For Info: I run a Acer Aspire V3 QuadCore Laptop, 2.6Ghz, 8GB DDR3 RAM with actual Windows 10 version and actual Kaspersky Total Security

 

Intstallation was easy and without any failure meassages at all.

 

About bugs:

Only issue I recognized was this one here ....

 

https://github.com/L...er/DSS/issues/1

 

...... but on a different way:

 

After test-stacking (20 lights, 5 darks, 20 bias, no flats) of M51 also my summary-picture was brighter than exspected.

However, I "saved as..." xxx..... for further use in postproduction.

But when closing DSS I regognized the Autosave picture on my desktop (I set DSS to do so).

The autosave pic was less bright than my manual saved and matched what i had expected the sum pic should be.

 

So somthing must happen in DSS between creating the autosave sum and final sum picture. 

Maybe that info help track down the cause of the issue.

 

With kind regards from nothern Germany (with actual grey sky  crazy.gif  )

Svend

I tried it with success.

I stacked 30 frames of Cygnus with EOS 6 + 85mm lens made a few months ago.
It ran flawlessly under Win 10 64bits (allocated 2GB memory) under VirtualBox on macOS.

Are there plans to port it to macOS (and Linux) ?

I just downloaded and tried the 64b version on some subs of the Iris Nebula I took with an SCT last summer. It's lightning fast! Thank you to all who worked on it. Out of curiosity, I compared the DSS final stacked image of 29 lights/30 darks) with the same subs stacked in PixInsight. Visual inspection showed no difference. I then ran both versions through several of PI's image analysis scripts for FWHM, eccentricity and SNR(weight). Here are the numbers:

 

FWHM PI: 5.503   FWHM DSS: 5.478

Eccentricity PI: 0.4960   Eccentricity DSS: 0.4889

SNR PI: 8.726  SNR DSS: 6.983

I have 64gb DDR4 ram and an i7 5820k processor (6 cores with hyperthreading, DSS sees it as 12 cores), plus I have half of one of my secondary SSDs set aside for temp files for DSS. I do know it blows PI out of the water in registration and stacking speed.

 

Now to see what happens when I toss a ton of full frame files at it.

Took almost 2 hours to register, calibrate, and stack the frames. I would say that isn't bad since each one is a 36mp frame.

680 frames @36Mpix... that is quite a serious stress test

Pretty sure that it's complaining because it is an exe file it's never seen before AVG did much the same but have since analysed the exe file and declared it clean.

685 36Mp lights in 2 hours - Gosh! Even I am impressed.

Once drizzle is incorporated that will be super amazing. If it could do noise calibration on the final linear stack I see no reason anyone would need PI.

I just (finally) tried it out.  Fast as greased lightning!  I AM GLAD TO HAVE IT BACK!  Not that it had actually quit working, but I wasn't sure it would be around in the future and had started trying out alternatives.

In case people looked at this without reading it closely:  DSS produced better stacks.  

Of course, PixInsight has many, many settings.  But the point is, DSS's defaults are at least a strong rival to PI.

We now understand the bug with drizzle processing where (when using Intersection mode) the output bitmap was 4x or 9x too large with the actual image in the upper left corner.

If you use either Standard mode or "Mosaic" mode you should not hit the problem.

Keep watching this space.

did a quick download of the 64bit version as I us Win 7 Pro 64bit.  after running the package I get the following error

 

"Missing api-ms-win-crt-runtime-l1-1-0.dll"

 

my latest C++ pkg installed is "Microsoft redistributable (x64) -14.0.24215 which should have the libraries required. 

 

my suggestion is for the "Runtime files & required Libraries" be included as the beta version as supplied will not install without them.

 

I have been using version 3.3.2 (Stable version 32bit) and love it.  would love to give the new 64bit version a go . . . :-( sadly not whats being served at this time.

To repeat an earlier post:

 

If anyone trying this gets: "This programme can't start because api-ms-win-crt-runtime-l1-1-0.dll is missing" in launch, the solution is to install https://support.micr...time-in-windows for your specific version of Windows (should only affect users of Vista / Win7 / Win 8.x who are behind on WindowsUpdates / running an offline system and opting out of WindowsUpdates).

I'd love to see a port of the code over to linux/mac...  Other than the windows interface, most of it should be somewhat portable.
