Very cool B+. In the beginning I tried to make everything without files but I had no idea that PAINT could have a start and end color, until you just showed yours. LOL

And to think I was just goofing off! Wow this topic went farther than I had anticipated! XD


Well here have an animated gif I made with me own pics!

how odd, it doesn't act like an animated gif... should be.. is on my hard drive...???
not sure whats going on that should be 9 frames but its acting like a single frame when I test downloaded it. not sure whats up with that.

Here's a wacky thought... What about using 'both' types of rotation. Disc in one direction and the arrow in the other... Talk about random...

How so?

I have over 100 images I took Thursday. I'm going to try and gif together, but I will probably turn it into a video and upload it to YT instead. as for some reason the forum don't like my gifs. and it will be several megs in size.

I was expecting comet tail to follow the direction it's going (why else call it a tail?) but I guess it always points away from the sun. Learn something new...

Comets usually follow long elliptical orbits. The "tail" does not normally show until it nears the Sun. Although the "body" of the comet follows the orbit, the tail, being less in mass, is influenced by 'Solar Wind' and as a result, the 'tail' will point away from the Sun. So therefore, when you see a comet, the 'tail' will indicate the direction of the Sun and not the direction that the comet is traveling. I hope this helps.

OK now about the UFO in one frame?

What's the scientific explanation for that? Elmo's Fire?

Lightning Bug. :D

Several of my Thursday batch have nice glowing trails cause the exposure time was ~20 seconds so any light that happens to flash in the sky gets caught to some degree. have some satellite trails too. missed the shooting star I saw Thursday, go figure! Supposed to be a bit of a meteor shower next week around the 28th I believe to be the highlight night.

Camera will only take up to 10 consecutive shots at a time, which takes just around 4-4 1/2 mins to complete so depending on conditions I might just catch one. but the comet was my highlight this year.
In 2024 when the solar eclipse passes over head I will be in the path of totality, for about 3:33 secs, or I could drive about 15 miles north and be in the center of the path! Hoping to have a telephoto lens for that one and catch the corona.

As for the static red, white, and blue dots, I'm not sure. Something tells me the sensor in my camera may be slightly damaged maybe? they don't really show in daylight photos, mainly just night shots.
