Photoshop Transit of Venus, advice

[04Stefan07]

Hey all.

What a transit that was! I could only see it between 8:16 (when it started) til around 11am. I managed to get just under 80 photos now I would like to photoshop some!

I have been playing around with Photoshop but I wanted to ask on here if anyone has properly done any photos from the transit? The most I have done is put an orange/yellow filter on the image (because of my solar filter the sun comes out white). Could anyone share or give me some advice on improving some images?

I also would like to have one image showing all the positions of Venus, I do have Registax but have no idea how to use it properly (the tutorials on youtube arnt too helpful either).

Thanks!

White light solar images usually have lots of granulation detail - but the detail is all bunched up in the highlights. Try playing around with the curves to see if you can bring out the granulation and sunspot detail, without over-darkening the limb or blowing the highlights.



Recent versions of Photoshop have an auto-align function (I've never used it), but I believe you can get Registax to output each frame post-alignment (again I've never used it). Once you have a sequence of frames properly aligned, you can add them as layers to the same image and choose a "darken" blending mode.
