In the now old days with CCD camera's, binning genuinely helped S/N as binning reduced the readout noise of 4 pixels to a single readout noise of the 1 superpixel. But with CMOS camera's that is not the case and all that happens is a software bin, averaging adjacent pixels and reducing image size, so there is no benefit. I would always recommend imaging at bin 1 and if you feel the image looks a little oversampled, then bin/reduce image size in your chosen software to suit. Nothing is lost.

Very informative and interesting. Love all the comparison videos you're doing, there are a lot of misconceptions in this hobby by people that recommend stuff because it works for them, or that's what someone told them to do, but in many cases it could be good or bad. It's nice that we get to test some of these things with actual data. Thank you.

Nice work explaining this. One thing you are not mentioning which I see no one talk about is the fact that increasing the binning to a higher value increase SNR at the expense of resolution which can be a very powerful tool in processing. For example In processing you can leverage that to mitigate noise in really faint part of an object that often does not have a lot of structure in these regions. bin an image at bin 4, stretch it ( you can stretch it further because of higher snr), resample the image to bin 1 value using interpolation and then blend all the super faint stuff back into the main image at bin 1… you are essentially using variable resolution workflow which dynamically lower resolution and increase SNR where details is not there but noise is.

thanks for putting examples behind the numbers luke! hardware binning did have a purpose with CCD sensors, when electrons were added up per row it actually did do more than just downsampling in terms of noise. but with CMOS sensors, there’s no difference between binning while shooting and just downscaling your image afterwards, unless you’re worried about storage space or something. and as you’ve shown, even when very “oversampled”, there’s still plenty of gains to be had by using everything your sensor is capable of!

I remember decades ago when the only cameras around were from SBIG and cookbook cameras (for those on a budget) binning was used to gain sensitivity and increase well depth because you were increasing the capture area of the cell. Typically the L channel was bin-1 for max resolution but R, G, & B were binned 2 to pickup sensitivity with a slight loss in resolution (but that did not matter since it was just color info). Have these benefits gone away with our modern CMOS imagers?
@lukomatico
Ай бұрын
Great question mate!! - with CCD sensors binning should be more efficient as they only have one injection of read noise per given read area, CMOS need to read out each individual pixel before binning can occur, leading to as many samples of read noise as there are pixels being read - but the good news is CMOS has such a low read noise in the first place, and the read noise is calculated within a square root, that it equals out in the end and CMOS binning ends up being just as efficient as CCD binning in practice 👍 Hope that helps!

Excellent presentation Luke. I've been thinking about this quite a lot recently for my RC which has a long focal length as well. I think in my case binning 2x2 would be the best compromise (especially on a full frame sensor) to take advantage of the 2x increase in SNR. Whether or not to drizzle as well would be an interesting experiment as drizzling reduces SNR and may well cancel out the benefits of binning.
@lukomatico
Ай бұрын
Thanks ever so much Pete mate!! - I think you're spot on really, bin2 and using APP to drizzle a small amount (1.2/1.3x) would be a really nice compromise at this focal length, and should help make storage and stacking of those massive full-frame files a little easier!! :-D Clear skies mate!

Shouldn’t you also take into account the seeing? If the seeing is poor, the oversampled image isn’t really capturing the detail that it feels like? And of course some of the post-imaging “sharpness” from drizzle and/or deconvolution is sort of artifactual, using math to guess what the missing values are. But it did seem like your sharpened images on bin=1 were “better” than what you got from bin=2, even though I suspect your pixel scales were far lower than your seeing? Very interesting!

Hi Luke, I switch from OSC to mono recently so my question will certainly sound "basic" (if not dumb...). When you shoot in bin 1x1, what scale setting do you use in PI for drizzling in your post-calibration. Is it "2" as most people suggest? Thank you!
@lukomatico

Hey David! :-) A good question I think! - I actually don't use PI for drizzle, but AstroPixelProcessor instead, where you could use a droplet of 0.5 and scale of 2 to achieve a 2x drizzle effect, - hope that helps!

What happens if you have the situation of oversampled data, choose to bin to gain speed and signal:noise… then take the image that is essentially 1/4 the size and go Image 200% (splitting that binned 2x2 pixel back into 4 pixels), then run deconvolution and finish processing?
