No report from CALSKY. It is a UFO.
CAPTURED with CANON G9 video under very bad seeing. The way of the object is NW to E. Look the video to see it. UFO CAPTURED TO AFOCAL VIDEO To plages today on sun and two staked photos to see them. TWO PLAGES ON THE SUN

Looked to me like a bug on the lens. It had a slightly jerky motion to it, like the way gnats walk.
In those moments of good seeing, the granularity came out nice though.

How much thousands km in height can fly a bird when i look inside of my teleskope with 17mm plossl and 7.5X digital zoom of my camera and i see a spot........?????????
The time was 11:25 am in greece that moment and the sun near to zenith. Nothing bug on the lens. The lens is sticky with the plossl. can i explain someone to me this think. I`m curious.

more clearly.
i speak for a spot over the big sun with 7.5X digital CANON zoom and PLOSSL 17mm on CORONADO. I speak for hundrend thousand km near to zenith. Can you tell me who much highest can fly a sattelite and how can you see from 17mm plossl only. Can fly a bird at the same height with a sattelite...???????

My thought was that it was a small bug crawling across the aperture lens/filter, not the eyepiece. It follows a noticeable curved path. A satellite would not do that.
A bird or plane might, but a plane would be silhouetted enough to see some detail like wings or the tail. A bird in flight would not have that stop and go jerking motion. I'm still going with a very small insect on the objective. They look just like that when they land on my glasses.

Well, it ain't a satellite because it changes direction...
Why do you think that it HAS to be at the height of a satellite? I see no reason NOT to think it's a bird.

If it is 2 feet wide (and if my 20" diameter guess is about right), then the bird would be flying at ~26,426 feet high.
If 1 feet wide, then ~10,313 feet high. if 3 inches wide, then ~2,578 feet high. My guess would be some kind of insect in front of the sun...likely a gnat. Formula: distance = (size/2) * 1/tan(apparent size/2) |

I decided on a bird rather than a bug because it would have to be a very large bug, far away, since the telescope would probably not be in focus closer than a few dozen meters. A telescope with the full sun in its view would be out of focus on a nearby gnat. It would help to know the focal length of the telescope and its f stop. We can’t tell the size of the thing. It could be a small bird 100 to 200 meters away. Also, figure how far away a bird or bug would have to be so that it would take that amount of time to cross the image of the sun, from our viewing position on the surface of the earth. |

I guess I'm blind but I've watched it many times and never seen anything but a hint of granulation and a pair of sunspots. They jerk around as tracking varies. Apparently the individual frames weren't aligned before making the movie. Where and at what time does it fly past?

Assuming a gnat is 1mm in size, that bring it to about 10.3m away...you would be able to see something (to a certain extent) at 10.3m while focused at infinite...I think. It's a Coronado brand, as he mentioned, so aperture is 40mm to 90mm. I've never compared the different apertures of Coronados so I can't tell that. More info here: http://www.coronadofilters.com/
The movement relative to a bird or bug's relative size will always remain the same. |

Assuming the top of the image of the sun is North, it comes in from the North-East (the upper right), and it flies South-West, then at the end it curves up a little toward the West. |

http://www.coronadofilters.com/Maxscope_70.html However, let’s think of this bird as having an insect in its beak. How about a grasshopper? The grasshopper would be in focus, but it would be larger than a gnat and smaller than the bird. Here’s a Solarmax photo. Imagine a small bird flying from the treetop on the right, across the top of the house. http://www.coronadofilters.com/images/CaK_001.jpg Another Solarmax bird: http://www.coronadofilters.com/Quick...arMax70CaK.jpg So, if the image in question is an insect, I think it would have to be as large as a grasshopper, or some kind of flying beetle. |

If it is a gnat who bigger you can see them with 17mm plossl and 7.6X Canon digital zoom.
The gnat closed my camera view. And i talk about zenith. And make the QUESTION again. How smallest is this object when i see a spot with 17mm plossl and 7.5X digital zoom from my camera........????????? Can you explain to me please. SAM compare the enlargement. It`s not the same. At coronao pics has full view of sun How can i see this bird in my video view. Is the bird much more bigger or not.....????
