I've seen the last two raw... The two objects with the same focal mm seem to have comparable dimensions... So you're telling me that it has apparent dimensions comparable to the Moon but much lower apparent magnitude? :-or

I think we have to work on the distance Richard, the moon is between 3500 and 4000 km, This object I do not know, it could also be 10-20km...

Yes, of course, I was talking about apparent size (I edited the message above), but my surprise comes from the fact that at 10-20km of altitudibe (in short, low, as the object should be to appear so large in the sky) nothing orbits, they are altitudes for flights or flying objects ... I can only think of a weather balloon, honestly.

I saw two of them every night, each with its own trajectory and time. Both at the shot are presented as you see in the picture.
Of course, even 40 km away would imply a "huge" size; only 100 times smaller than the diameter of the moon.
I suspect a behavior, undeciphered for me, of the maf of the EM1II Oly.
When I identify the target I activate the digital zoom and then I work with the back focus, I would not want the camera, autonomously, to create the best conditions for shooting.
Let me explain: I see the moon small (1 cm?) and at the zoom it fills my viewfinder, the mysterious object from a very, much smaller size, takes on the same size as the moon. I don't govern this passage... 8-)

I only now read your PS Riccardo, so can we opt for an exaggerated manipulation of the Oly camera?

According to your last clarification:
the moon I see it small (1 cm?) and at the zoom it fills my viewfinder, the mysterious object from a very, much smaller size, takes on about the same size as the moon. I don't govern this step

I think you know...

It remains to understand only what these mysterious objects do :-D :-D

It would be useful to have a visual experience, even with good binoculars. Those concentric circles leave me quite perplexed about the possible identity

At the moment I do not have the availability of a good binoculars, are you referring to an x10? I
have to ask around among friends if I can find a telescope.
If there are developments I inform you, meanwhile thanks :-)

For the record, I got to those sites with a search for images with the published photo...

The one in the video is, without a shadow of a doubt, Venus. Increasing the zoom you have to adjust the focus, which is not done in the video, and this creates this effect.
There are apps, like skysafari, that tell you exactly what you see in the sky in real time. Try installing it.
So I would say that what you photographed yourself could be a blur of Venus

In fact, what leads astray is the process that leads to the strange outcome.
Riccardo had assumed that it was Venus, but he did not give himself credit ignoring this atypical "reaction" of optical systems.

The dimensions in the frame are therefore only the result of digital zooming, as you suspected Look. There is also a
case, PhAstro, that the MAF is also correct, but that with only 210mm on m43 you can not get anything better from a single capture of the hypothetical Venus ... I think I would also be tight with the meter and a half focal length of the Maksutov (on which, for the full "round" moon, I need the 12 or 15mm eyepiece if I remember correctly) ...

Be careful because the visual and the photograph are two different things. I would not be fooled by these parameters. I simply estimated that a month ago (hypothetical date of the video) in that position with the moon at sunset there was both Venus and Mars. Venus obviously wins in size.
The hypothesis of Venus would also justify the motion described by Lookdido

Yes, now everything is clear, thanks for the contribution.
You have to change the title from "satellite bottom" to "blurred Venus" that intrigues as well ... 8-)

:-D You will have to put it in the "naked" section :-D
