Hi all,

I've made a little picture of the current activity on Sun .

Verry nice- I was looking at that myself this morning!

What did you actually use to get that pic?

Hi all,

here are some more shots one day later.





Jack, my equipment is only a very cheap 70mm refractor, a web-digi-cam and a white paper sheet as screen. Ok, I improved the pictures a bit with Photoshop.

how do you improve pictures with photo shop? i amde some moon pics and they need to be improved, how can i do it?

Adjusting brightness & contrast, colour balance, things like that! It's usually to improve the variation between similarly coloured areas of the sky/object you're observing.

Another thing you might want to check out, ElPelado, is RegiStax, which combines several digital pictures of an object to bring out the best possible image. You can take a picture of something very dark & it brings out the detail like in nightvision or something...

Hi ElPelado,

there is no common way how to improve a photo. Gamma, contrast and brigthness correction is the first step. Further you can use carefully gaussian blur with unsharpen mask to bring up details by limiting the noise. Sometimes is also useful to change the mode to LAB color to optimize color information and albedo separate.
