First, the link!

 

It has better graphs for frame selection plots with more variables, improved performance with registration, and some better astrometry tools. But most importantly, it has its first version of pixel math!! For those of us without PixInsight, this is a much needed addition! Excellent work by their devs!

Awesome! I saw a new version was hot off the press, but haven't looked into it yet to see what was added as its been an 72hr+ week at work for me.

 

I've heard the term pixelmath a few times but not too familiar. Is that what allows one to scale different sized images to be stack together?

pixel math simply allows you change the values of pixels based on mathematical expressions. For example, putting stars onto a starless image is just adding the two together. It's also used for mapping the colors of narrowband images to the RGB channels. But some very smart people put together very complex expressions to do some transformations with more finesse than possible with other tools. Another free program called Image magick can do pixel math, but it takes work to translate PI expressions.

I downloaded over the weekend.  Extremely beneficial update.  Even runs faster in some respects.  It also includes sensor tilt analysis (cmd: tilt) which is fantastic.

That "tilt" command is fantastic. I've never bothered installing/learning CCD Inspector or ASTAP for their tilt analysis. I've always just used PI's FWHMEccentricity script with support. I've always suspected a bit of tilt in my images. Well... I have SiriL, so I opened up a sub and ran the tilt command. Yup... there's some tilt there. Couldn't be easier... just type "tilt" and it gives you a nice graphical representation of the tilt.

 

SiriL is really a great tool that has had a lot of hard work put into it.

 

Edit to add some visuals :)

 

First, is the result of the tilt command for a sub taken with my GT81 and 6AIII:

Next is the result of tilt for a sub taken with my GT81 and the Hotech 2" flattener I just got:

Thanks for the Tilt command. I also did that and this is my result,

Does this mean I have to start adjusting the screws on the top plate from my ASI2600MC?

I used pixel math this afternoon in combination with StarNet++ to produce a pure star image by subtracting the StarNet++ starless (nebular) image from the original stacked image.  It was as simple as: file1-file2 in the work window.

That can certainly be done in photoshop as well, but it takes a few layer duplications and blending mode changes. It sounds easier in siril if that's where the initial stretching and color calibration is done already

I've always done that in gimp by adding the starless starnet++ image as layer above the original in subtract mode. I don't see how it could get any easier. 

I'd say it saves you a trip to Gimp if Siril can do it, but I'm going to be taking the stacked file elsewhere for final tweaking anyhow. 

Curious what other functions it can do though, I know I've heard pixel math quite frequently on the forums.

 

The tilt feature looks interesting, perhaps it will help me troubleshoot one of my modded cams that developed what seems to be a bit too much sensor tilt after I modded and moved the sensor a bit.

Runs so much smoother on m1 mac than previous versions; no more click and pause. I'm hoping the full release will have a higher resolution GUI. As it currently stands, the font appears a bit blurry for my liking.

Sadely, it is unlikely. This "blur" stuff is a workaround for a GTK3 bug with MacOS platforms.

That's a shame. Excellent work btw :)

Does it only work with fits files? I tried to add starless tiff files and it could only see fits. 

 

Also can someone tell me how to combine narrow band channels?

 

I use an l-extreme with my modded Nikon Z6II, so usually I extract the channels in PS and use Starnet++ to combine starless channels into one and then add the stars.

Yes but Siril can convert your files.

Rc2 is out! https://staging.siri...iril-1.0.0-rc2/

Comes with bug fixes and a video introducing how to use the new plotting features.

Update and enjoy!

If the bug fixes include fixing "shuts down if you do too much", I'm excited!

I'm using this version on Windows and I find that the program terminates after most manual "add to sequence" operations. script based processing seems to work fine

1.0.0-rc1 - however I just turned it on it's prompting me to download 1.0.0-rc2.

I will experiment with this version when I get the chance.
