Your videos are always so good and well explained. This one in particular makes we excited to try binning. Love the visual examples as well. Thank you!
Nice video. Thanks. very interessting. What about binning for a better SNR and after that using 2x drizzeling to get more resolution with a better algorithem than just blowing up pixels?
The only problem is with my zwo planetary camera, when I'm imaging fainter things like Pluto, the eagle nebula or the pinwheel galaxy, i want the best resolution but if I use binning 1, I have to dramatically increase exposure time to even get the image to show up
I notice that when you were discussing binning at the start you talked about summing four pixels when binning 2x2. When you performed the operation in Pixinsight the binning mode was "Average". There does not appear to be an option in Pixinsight to bin 2x2 by adding the four pixels. Can you comment on the difference between average and sum binning?
This is excellent. Is it possible to downsample just the OIII and SII (since they typically have less signal than Ha), and then combine them with full resolution Ha image? Or can you not combine images of different scales?
Oh Lord! This was in deed an impressive presentation. I've never went so deep in thinking about binning. But some questions arose in my mind: What if I would shoot RGB in bin 2x2 with my CMOS ASI to gather signal and would shoot luminance with bin 1x1 to gather resolution? Could I down sample the luminance in Pixinsight and aline it with the RGB data? CS Christian
Question. I'm getting into Astrophotography and want to buy a PC or Mac. Would Mac suffice for doing editing or is there more varied applications on PC platform.
I badly need to bin but i'm confused about software bin vs hardware bin, if it can all be done on cmos in software/post, there's no need to bin while shooting? (Well in my case it might be anyway since my mount is performing bad). What makes your complete composed stack so clean? Even tho your S and O is more noisy
@What could go wrong? - Niagara edition I wonder if i can bin the already binned photos of my phones cmos sensor. Unfortunately i can't afford PI. So, is there any other software to bin photos? Also my phone does a 2x2 binning at 12mp, could i apply a 3x3 binning with a software to achive 5.3mp photos out of 48mp unbinned image? Thank you.

Thanks a lot! A real world example makes a while lot easier and makes a stronger argument to bin or not. Until now I only heard verbal advice. But seeing it in the works is mind blowing. One question. Is it any different to do binning while shooting (each sub is binned) and after stacking?
File size for each sub will be smaller if you bin when you capture. A lot of times I don’t know if I’ll want to bin when capturing, so I like to do it after the fact. But if you know you will do it, you should do it up front to save space and processing time for each sub.

@@lazyastronomy3348 I tried binning while stacking but deep sky stacker doesn't have this feature.
@@lazyastronomy3348 This is great thank you. This may vary from camera to camera (CMOS) but have you noticed a quality difference in binning in-camera vs after the fact in PI? I've heard the PI Integer Resample does a better job but I haven't been able to test that yet...
Very interesting, couple of questions you said binning but did you bin the image after the image was taken. I thought you do the binning just at the time of acquisition. Also you process the image as a tiff and not xifs ? Thanks for the video..
With an older CCD camera, you bin when taking the image because of hardware advantages that reduce noise even more. But modern CMOS chips don’t do that. You can Bin when taking the image to make a smaller file, but since it’s all just software at that point, you can also bin after the fact like I did here and get identical results. As for the Tiff processing, I had to save as 16 bit Tiff for the Microsoft ICE program to read the images to put the mosaic together. Otherwise I would have kept it as xisf.
@@lazyastronomy3348 So after you save as a tiff file you can use Pix to do the rest of the adjustments ? I liked how it took the image and stitched it , so easy , but never did any adjustments as a tiff. You treat it the same way as xisf ?
@@lazyastronomy3348 thank you for this. I can’t find a solid answer on whether there a benefit to doing the binning in PI vs letting the camera do it (cmos camera ASI183mm) You say identical results but I hear so many people say it’s better to do it in software, but I never hear why.. I just hear them say ‘it’s better’’ how exactly? :) thank you
Hmm... you seem to be interested in the resamplings effect on the dynamic range. Why not just increase the dynamic range using other tools rather than destroy the resolution? HDRMultiScaleTransform for example?
HDRMT doesn’t help with noise unfortunately, and is best used when trying to bring more detail out in high signal areas. Binning/resampling has a mathematical effect on the noise in the image, which is helpful when dealing with low signal narrowband or color data.

Really helpful video. Your explanation and supporting presentation material was first rate :)
This channel incredibly underrated.
Exactly the video I was looking for as to binning in pixinsight. I like your style. Great video.
Thanks so much for this excellent tutorial. Question, please: Is binning done in post or during sub captire? Thanks, Michael
Nice video. Thanks. very interessting. What about binning for a better SNR and after that using 2x drizzeling to get more resolution with a better algorithem than just blowing up pixels?
Excellent presentation! Thank you so much!
You nailed it. Great explanation
So if i use something like a asi2600mm with 3.76um pixel size on a 200mm lens and I do a mosaic, I can increase the resolution?
The only problem is with my zwo planetary camera, when I'm imaging fainter things like Pluto, the eagle nebula or the pinwheel galaxy, i want the best resolution but if I use binning 1, I have to dramatically increase exposure time to even get the image to show up
im going to try that with my 1600 SHO IC410

Great video. Thanks.
Does anyone know how to do it on gimp?
It’s the Scale Image command. docs.gimp.org/2.10/en/gimp-image-scale.html

Come back. We need ya. It’s hard to balance real life demands with a night of astro outside, I know. 😄

I have asi585 and I tried bin 2x2 and had more noise than bin 1x1

I’m confused what picture what binding was
