Looks good Pedro!

[Pedro]

Thanks Walter and Alexandra:

It seems overprocessed but I had to do lots of things in PS CS5 (High pass, S&H, unsharp, smart sharp and a mask - artificial flat). Here's the unprocessed image. The Baader CaK filter is not bad but you have work a lot to get a correct image.

Hi Pedro

thank you for that unprocessed pic. That already looks great, huge details. I wonder with what I end up with it

[Pedro]

Hi Walter:

I checked the image with another screen and you are right (it was a bit overprocessed). I already uploaded a new version. Check it out:

Alexandra.

Can you please send the link to your CaK paper (PDF). It seems I have misplaced the file.

Thanks

Hi Pedro

thank you very much for your unprocessed file. It behaves totally different then my pics, but any how, here is my version of your wonderful shot

[Pedro]

Looks great Walter. Different colors and processing.

Nice Mark. Great contrast without blowing the histogram away.

Pedro, I see you have entered the mysterious world of calcium images. Awesome!

Hi Chris:

The image was obtained with the Baader Calcium K-Line filter. I am now considering buying the LUNT 1200 Cak Module...

Hi Pedro

although I do not get a provision, you will be very happy with the LUNT CaK wedge. It is absolutely maintenance free. Stick it in and shoot hmy:
