SIRIUS the MOVIE

[geppetto]

Humour me with this one...

Wanted to image the fantastic colour display from Sirius.

Anyway, found the best way was to de focus the star

then save an AVI from the toucam.

Split the avi into BMP's and made a short animated Gif from them.

You might have to wait a few seconds for the frames to load

Pretty isn't it

Lovely stuff Phil. I do like that ol' twinkly Dawg!

[Kaptain Klevtsov]

How cool is that? Ace shot Phil!

I can't tell but I'm guessing that the colour is the same for all parts of the image in one frame?

Now I just need somebody to tell me how it does that.

It's interesting to look at the individual frames.

Each frame is randomly multicoloured and a beauty in it's own right.

Tried to get the effect on an avi of a focused star but it

wasn't as dramatic as the de focused one.

[Caz]

I'm impressed, look at all those glorious colours!!.. Wonderful, and very clever 8)

[MartinB]

Ingenius and very effective

[geppetto]

Thanks folks...

CC

Here is one frame to show the colour is varied around the star all the time.

[SteelRat]

Good stuff Phil 8) Dead clever mate.

[Jaffa007]

Phil,

That is amazing! Love the colours.

I think you could of started something with this de-focuseing imaging....... 8)

[Vega]

If it wasn't Sirius, I would say you got a SERIOUS SERIOUS Chromatic Abberation problem

[Chris Graham]

wow......thats a lot of colour !!!

Really good experiment

[Kain]

De focused imaging - Theres hope for me yet!

Nice one Phil, amazing the different colours Sirius twinkles in.

Fun to look at. It would be interesting to see that done with a refractor, to see it without the central obstruction.

[barkis]

Looks like a gas ring before you put the chip pan over it.

Phil

Excellent idea to do something a little bit different.

You can see how Sirius gets mistaken for a UFO

Could someone try this with colourd doubles, ie Abireo, Gamma Andromeda. Maybe not quite as defocussed. I bet they'll look pretty good too.

I will give it a go when I finally get my gear up and running. I seem to have been saying that to myself for months now.

I am retired, but I seem to have such a lot to do. Computer repairs, Alternator repairs, starter motor repairs. My time in never my own.

Who' started playing a flippin violin.

[GordonCopestake]

Which scope was this through phil? If it was an APO I would want my money back hehe

[geppetto]

200mm F6 reflector I think Gordon...

Def not an APO, Geppetto Towers is an APO free zone (for now that is)

[GordonCopestake]

hehe, you know you want that ED80 to join the stable ...... you can't resist!

Would love one mate... been keeping an eye out for a second hand one but they seem to have dried

up for the moment. :?

How did I miss this one? Shame on me...

It's simple refraction. Looking at a bright point source through lots of air creates a prism effect, much like bad seeing causes a blobinator effect. The low angle to the observer causes the light to bend and split into its colored components, giving this colored twinkling effect.

[shifter]

Simply amazing :shock:
