Reasonable seeing today with high thin clouds. Could you please give me some pointers on colourising the images Ca-k, Ha and yellow for continuum. Thanks.

To colorize you gotta convert the image to RGB first,     If you are using gimp just open up the levels adjuster and individually change red channel green channel and blue channel.

 

See attached photos.

I use Irfanview (freeware) to colourise my solar images obtained from FireCapture/ AS3!/Imppg.

Image tab/ Color Corrections/

R/G/B/Brightness/ Contrast settings:

WL = 75/38/22/0/0

CaK = 25/-5/105/8/-2

Ha(surface) = 84/-14/-114/9/14

WL and CaK setting shown.

You can play around to find a combination you like.

(you can also remove the background using Replace Color)

Merlin:  your settings have  killed the limb    He's captured a delicate spicule layer in that calcium image.

Thanks alot, I use Astra Image for processing and output from Autostakkert! 3 in PNG so I´ll give it a go. One other thing is, how do you fix a Baader blue filter in  front of a Lunt Ca-k module ?

Takes a bit of sleuthing to find the right parts, but if you have a 2" b-ccd filter you can just attach it to a nosepiece on an extension and slide the lunt filter into that extension.   

IF i am not mistaken, the back end of the lunt assembly is a standard T-thread, so you can disconnect it and adapt it to something like a baader planetarium barlow.
