PixInsight For Dummies (Like Me) | Part 3 - Stacking

[@doncarter1414]

Peter, you don’t need to manually type in all the astrometric solution data. If it’s not happening automatically (which it should) use image solver.

[@RonaldKools]

Awesome tutorial! Small tip: to save a little bit of time, you can use the directory option. It will select lights/darks/bias/flats automatically by detecting the type from the Asiair folders.

[@pompeymonkey3271]

The Image Solver will automatically take the coordinates from your fits headers. No need to manually populate the details.

I've never had to input anything into "astrometric solution". All the data is embedded into the substack and then transferred to the stacked image. Unless I crop or physically alter the stacked image SPCC works without any image analysis. Which is the only reason I can think of for the positional data. Am I missing something? Is there another reason to fill in the "astrometric solution"?

Silly question-If I have different exposure images say 600sec and 300sec in the same stack does WBP stack into one image.I often see that there is a 300sec master and a 600 sec master have they also been combined. For example, if you have 5 hours of 600 sec images and 5 hours of 300sec images.Is the master a total of 10 hours not 1-5 hour 300sec and 1- 5 hour 600sec image?

Excellent Peter! Thank you.

Hopefully this helps someone, Back on part 1 when we adjusted PixInsight's access to the number of threads, I set it to the total number of threads that my computer had (24 threads on a 16 core CPU with 64 GB of RAM). When I ended up following this stacking process to stack around 7 hours worth of 3 minute exposures, I kept getting an error saying I was out of memory. After several wasted hours I ended up solving the problem by reducing the total number of threads to the total number of cores that my processor has. But overall this was a great tutorial and I ended up getting my data processed quite nicely.

Still loving your tutorials! I was originally using a stacked image I put together in siril but figured it would be worth a comparison. I'm glad I only managed about 40 minutes before clouds rolled in for my new camera test and most recent image! about half way through and about 15 minutes in. Not too excited for my first full night of images! xD Currently very jealous of your 24 cores... vs my 4 on an i5

VERY helpful Peter! I purchased PI and the addons but my poor laptop is straining with the program! Could you please give us a breakdown of your computer? I'm already running two additional screens with my laptop so just want to know what your computer is. Thanks!

If you want to remove individual images after checking (Blink, etc) after adding the file to 'light' frames in WBPP you can select then remove any image you want to remove.

Many thanks for making these videos mr.Zelinka! I have been "procrastinating" PixInsight for a long time now. Uses DSS and Siril + PhotoShop, but I can see that PI is the über tool for getting the best results. Thanks for giving me the "push" to buy/start using PI. I also just love your pragmatic approach to not bother taking "calibration shots". I don't bother either, but I see hard-core astrophotographers are of the opinion that you *must* take calibration subs. I see the need when using a ASI294MC though, so I have at least bothered to take flats when using the 294.

There is a button in Blink tool move the bad frame to a different folder, but you still need to uncheck it to remove from blink view. It’s the icon just left of the sissors icon.

[@jtepsr]

Can you explain the app setup with just a color camera, how do you modify with the cfa button

[@Ben_Stewart]

Thanks for tutorial. I have been avoiding WBPP but I might start using it some more.

[@peresanz116]

Thank you very much for these PI tutorials! I would love to see a tutorial on how to stitch a milky way panorama with PixInsight.

[@trainfan7823]

Amazing series. Just got PI and this is so incredibly helpful, thank you!

[@antoniopelaez7148]

Perfect.Thanks from Spain.

[@alexweinstein3041]

Thanks for the video. You can actually close an image you don’t like in Blink by clicking the second button from the left. I close all the images I don’t like, then select all and click the folder on the left and move all the images to a new folder I label as “approve” or something.

[@alexweinstein3041]

I also like Astro pixel processor more for stacking. It’s much more streamlined and far faster than PI (I process in PI).

[@keithhanssen7413]

You said PI stacks better than DSS. What specifically does it do better?

[@dbkokinda]

Local normalization and weighting are huge factors in determining/increasing the quality of the output. It definitely takes longer with WBPP, but to me, it's noticeably higher quality.

[@Arcteek]

Excellent video thank you

[@yervantparnagian5999]

Amazing series.
