So what was it set to? f4.5? f8?, Shutter speed 1/250 or 1/500? Those are details that you just gloss over and pretend that it doesn't make a difference.
I think you mistake a simple camera specification (which was asked for) with something that matters to the actual measurement of the image size on film.
Was that task to take photos that resolve detail in what, to the naked eye, looks like point sources?
Oh yes indeed - they were conducting laser experiments which required fine resolution photographs.
Yet strangely you feel compelled to carry on regardless…
If, in fact, there was actual strucure seen in the film and not a somewhat shaky photograper.
I stated:
“You are simply incorrect here. If it was a simple “shaky long exposure”, there would be no blobs – just a (perhaps convoluted) continuous steak of light. To get a blob (or blobs), one needs to hold the camera steady. Moreover, in the previous photos in the series there is absolutely no evidence of any shakiness whatsoever – there is none in the photo of interest either (2141).
In a "normal" squiggly image due to hand vibration, when the total image is concentrated near the centre of the photo - as in this case (i.e., when the squiggle lines do not go off the edge of the photo) - there are only two ends - one of which corresponds to the image location on the focal plane when the shutter opened - and the other end which corresponds to where the image was when the shutter closed. The image in the fourth photo appears to have three "ends" of red lines.
Further: the camera with a 300 mm lens had considerable inertia, resisting hand vibration and the shutter speed was probably faster than 1/100 sec (other photos were taken at 1/250 to 1/500 sec). There were no vibrations of the Skylab 3 so any such vibration would be due to hand holding the camera, but in free fall (in orbit) the cameraman was not fighting the weight of the camera, so this would reduce hand vibration.”
Please show that it would be impossible for one single frame on a roll of film to be affected by disturbances during development.
Oh…I see… I am now asked to prove the impossible… but perhaps you have simply misunderstood scientific theory. It is impossible to prove the impossible. The best we can do in
any research project is come up with likelihood estimates based on the available evidence. So, based on the available evidence that all the surrounding pictures on the same roll of film show no “disturbances during development”, the best we (or
anyone) can do is to state that it is highly
unlikely that any single picture in a roll of ostensibly and otherwise soundly developed pictures shows anomalous development “disturbances”.
A fact that makes it more likely that there was some problem with un steady camera or disturbance during development. I haven't seen any of the austronauts report that they saw any structure.
I have already shown that it was highly unlikely to be the result of an “unsteady camera” (see above). I have shown also that it is highly unlikely to have been a “disturbance during development” (see my previous replies to you). They reported that it was red and they assumed it was a satellite they did not know about. A 300mm lens can resolve things the human eye cannot perceive.
...not what I was asking for. I asked you how you know they use a micrometer.
I asked the authors.
So they thought it was ok to assume that the length was perpendicular to camera but not the width. I see...
No you don’t see at all. The point is that they had to measure somewhere across the object to calculate at least a
minimum size – and the longest extension was a logical place to do this. There is no need to assume perpendicularity because the eventual size was much greater (even including the error bounds) than any satellite anyone had up there at the time.
That, is the end result of the calculations Jocce and
that is the critical conclusion that needs to be drawn here. If the minimum calculated size turned out to be close to any existing satellite, it would have been a different story and all this talk about error margins would
then have had direct relevance. However the
minimum size of the object, even accounting for possible measurement error at every step, was
STILL larger than anything up there at the time.
Still a more plausible scenario than an object unknown to mankind.
So…according to you,
mankind knows everything. This is rather an extraordinary hubris on your part don’t you think Jocce? ThatUFO debunkers believe that we
know everything should nevertheless come as no great surprise to anyone who may have spent some time perusing this thread.
Ok, so you were exaggerating a bit with your 1-2 seconds precision then? How old were the austronauts?
An average three seconds error over three minutes translates to one second over one minute. I stated:
“Normal people have a very good sense of time. If asked to estimate the span of a minute (for example), they can generally do so to within a second or two (many can actually get it bang on).” and that would seem to be an entirely accurate assessment of the research here.
Now if we take that down to estimating over five or six seconds, then we are talking about error margins so small that they simply do not matter. Even in the 60-80 year group cited, that translates to an error margin of merely one second – so you can see that
on the research evidence I have not overstated my case. And the astronauts were certainly
not in the 60-80 year old group (they were all in their early 30s -
http://history.nasa.gov/ap11ann/astrobios.htm#other).
So your claim is that this article proves that people who can't estimate time better than with a 1-2 seconds (over a minute) margin has a mental disturbance? Wow...I need to see a doctor. I was actually trying to do the counting method the austronauts used and I was really surprised how fast you need to count to get it right. First try I got 9 seconds...
It is not for me to comment here on your mental status – for that you would need to seek a private professional consultation.
We're not talking about orbits. We're talking about the distance between two objects and the error margin is 25%. Would you say that an estimate of 0-38km gives a small error margin?
Error margins are
only and
specifically relative to the calculations they arise from. The whole point is that in the size calculation undertaken by the authors, even on the most conservative estimates (factoring in the largest errors), the object was larger than anything mankind had up there at the time… and
that’s the telling conclusion from all this Jocce.
Why do you write such a long piece of text when you still don't respond to what I posted? It is ASSUMED that the photo was taken when they went into shadow. But it is an UNFOUNDED assumption. Get it now?
What you have seemed to have missed is the relevance of my statements to your claims here. The astronauts determined that the object was tracking them in a very similar orbit and at a similar speed. This they could have done. What they could NOT know was the size/distance ratio – and so as to enable others to determine this, they measured the time between when Skylab went into darkness and when the object followed. The assumption is actually in whether the astronauts were capable of determining the objects orbit and speed, because if they COULD, then it does not matter
when the photos were taken in the 10 minute period of observation. Get it now?
