I will see if I can take some. Although given my EAA setup I will be limited to less than 30s which is why I use stacking.
Single exposures are really not a very good way to evaluate these sensors based on newer technologies for a couple of reasons:
1) These are raw sensors, unlike video cameras they don’t have DSPs which perform noise reduction, sharpening etc. so it is an apples to oranges comparison.
2) Given the incredibly low read noise you want to use these cameras at the highest possible analog gain to maximize SNR and build dynamic range in software via stacking. With single exposures are you are seriously limiting the potential of the technology.
Also not sure why you don’t want me to bin. Binning reduces shot noise which is what you want for single exposures.
Hmmm, just read this post after I posted mine.
If this camera is that bad at single frames, without stacking or Binning, then it isn't much good for near-Live 'Video Astronomy' style of observing which is what I prefer to do.
To me, all these moves towards longer frames stacked constantly, is Astrophotography. Yes, it's an old argument that rears its head from time to time, but it's also correct. That's why it keeps coming up.
This is supposed to be about 'Near-Live'.
So it appears, from your comments quoted above, that I won't be bothering with getting the 385.
That is fine. Each to his own. Just because you prefer a particular style of observing does not mean it is the only way to do ‘video astronomy’ or ‘near-live’ observing. This is not astrophotography by any stretch of the imagination.
But ironically even the so called ‘video cameras’ stack and heavily process the image internally. The only difference here is the user interface.
Honestly, I never liked the images produced by ‘single frame’ video cameras. Just personal preference. They just trade sensitivity for resolution and quality of image. In my view there is nothing wrong in wanting better image quality for live observing. I like to move forward with technology.
Finally, not sure where I said this camera was bad at single frames. The point I was making is that it is a waste trying to make new technology behave like old technology. We need to learn to use new technology and tools and also keep an open mind to what is ‘video astronomy’
Also what is wrong with binning? Even with binning resolution is better than some video cameras... smaller pixels in newer CMOS cameras provide significant flexibility for different styles of observing... in your view using binning makes the camera no good for observing... hmm...strange
