Sorry, I missed your question:
Hi I just wondered do you see images like those photos when you view visualy through your telescopes? or does the camera bring out far more detail
Genarally, the answer is that while I can see a great deal of the details given either excellent seeing and/or great patience, I think the average observer would look through the eyepcie of a C14 and say "It dosn't look like the pictures, dude!"
And they would be right.
The human eye does not have the contrast sensitivity threshold of a modern CCD camera.
In a large scope when viewing Jupiter, the eye is working just above the scotopic vision threshold, in a mode called Mesoptic. Some of the color perceptors are firing (this is of couse how you know, because in scotopic mode, you only see shades of gray.
I photopic mode, the eye has a contast sensitivity of perhaps 2% meaning that a detail has to have at least 2% difference in contrast between it and the area around it to be easily detected.
When the eye goes Scotopic, the amount of contrast required for the observer to see a detail is quite significently increased, and this actually varies considerable with observer... It is one of the true big differences people have in their vision that cannot be corrected with lenses (or the telescopes focuser knob).
Also, in scotopic mode, the eye has the best sensitivity to low contrast detail when it occupies a very specific spatial frequency (the extent of the angular size in arc minutes of apparent
field ) that is about 5 to 9 arc minutes. If the detail gets much bigger or much smaller than this, it can be difficult to see it.
For Jupiter in a large scope using Mesoptic vision, the figures are somewhere between this. Most people will have a contrast sensitivity that ranges from about 5% for large details down to about 10% to as much as 15% for the smallest detail.
In other words, all of the detail is there, but the human eye is just not all that good at seeing it.
This is why when you read about MTF charts, you hear words like "the important low and mid frequencies" to visual observing because these are the frequenceies that we can magnifiy and still have sufficient brightness to see them well. The low and mid frequencies basically means detail that is a couple of Airy Disk diameters or larger.
If we overmagnify, to make the finest detail big enough to see well, it looses brightness, and this makes it harder to detect.
In a nutshell, the answer is no, I can't see the same level of detail using the eye alone.
Using the C14 on a night of excellent seeing, I will be luck to see the same clarity as shown in the C11 picture on this link and it takes tremendous concentration. None but the highest contrast details leap out.
At the eyepiece they are very subtle and require a lot of patience and persistence. Jupiter in a single glance will not show nearly as much detail as seen in the C11 image at thet top of this post. A lot of it is there, but you really have to work to see it and the smallest angular detail will start to dim out if I over-magnify because the image dims so much.Remember that many of these pictures are taken at hugh magnificaitons! I use a barlow in my C14 to image giving it a focal lenght of almost 4000mm! Try using a 4" scope at 500x and see what happens to the crispness of the image!
I don't care how perfect the scope is... The image will look soft visually. But the camera shows huge amounts of detail!
The camera benefits from having a lower contrast sensitivity threshold than the eye, and modern stacking eliminates the noise that plagues both CCD chips and the human eye when the image gets dim.
It is just that modern CCD technology gives the camera a better contrast sensitivity and stacking enhances the presence of low contrast detail..
Forgive the long answer. I want people to know that Jupiter never really looks like it does in the pictures, but a lot of the detail is there for someone like Norme that has the patience to look for it.
MTF is another way of saying "Sharpness." A scope with better MTF produces a "Sharper" image because details stand out better and have more crisp borders (hence the example of the various ovals in the two pictures) and what the instrument can do and what the eye can process as compared to a CCD chip and softwere enhancement are two very different things.
