Concentric Circle Solar Ruler

[GUS]

Hi,

I would like to share with everyone a solar ruler 'mod' I made. Cheers!

Thanks for sharing that, I'm going to try superimposing it on my own images, so very much appreciated.

That could be very handy indeed. Thanks!

I prefer Guy Buhry's original , all those concentric circles will obliterate most of the captured features in a solar image ...

Thanks everyone for the feedback! Taking into account Steve's observation, I made two slightly more minimalist versions, in black and in white lines for a less obstructive view depending on the wavelength to be superimposed on. And thanks to James responding to Steve, I discovered google sites from where you can download the originals! (They're at the bottom of the default page which I haven't yet bothered modifying). I attach two examples although personally I think black works better in all cases. Everything was done in Paint. Cheers!

As I said before , they completely overpower the underlying image and ruin it ...

Well, it's meant to be a temporary superimposition for the purpose of quickly counting the inner circles comprising whatever surface feature you want to measure, to get a faster measurement than you would with Guy Buhry's original, precisely because the circles cover the whole photo, so no centralized twisting is required, the whole point of an alternative version - facilitating and speeding up measurements.

Really helpful thank you. And for those who worry about the image being ruined, simply increase opacity as a layer in PS and you're done:)
