Demonperformer Posted September 29, 2011 Share Posted September 29, 2011 Like many others, I have been following the progress of AR1302. However, I have been rather puzzled by the fact that all my images have been blue:icon_scratch:. If I greatly increase the exposure I can get rid of the colour, but as that also tends to get rid of any sunspots as well that does seem to be a little self-defeating.I am using the 102SLT stopped down with a 50mm solar film filter on the front and it definitely does not look blue when viewed visually.The only thing I can think is that it is something to do with the fact that the canon has been modded and has a CLS clip filter 'jammed' in the slot (i.e. I can't remove it) and a UVIR block filter is screwed into the front of the nosepiece. Would that combination account for the weird colour (not that I particularly dislike it, it's just strange)? Or do you think something else is going on?And yes, I know, my focussing leaves a little to be desired!Thanks. Link to comment Share on other sites More sharing options...
Merlin66 Posted September 29, 2011 Share Posted September 29, 2011 I'd have to say it must be associated with the bandwidth of the CLS filter.A Uv-IR doesn't do this. Link to comment Share on other sites More sharing options...
jgs001 Posted September 29, 2011 Share Posted September 29, 2011 Yeah, I'd agree, it looks a very cls tone. Nice image btw... why not convert it to monochrome and then apply some yellow colouration to it ?? That's what I do. Link to comment Share on other sites More sharing options...
Demonperformer Posted September 29, 2011 Author Share Posted September 29, 2011 Thanks guys, guess I will just have to live with it then.Interesting suggestion, John, to convert to b/w & add some yellow coloring. Might well give that a try. Thanks. Link to comment Share on other sites More sharing options...
jgs001 Posted September 29, 2011 Share Posted September 29, 2011 that's what I do to mine.. otherwise my white light images wouldn't have that toasty yellow-orangy-ness to them. Link to comment Share on other sites More sharing options...
markt Posted September 29, 2011 Share Posted September 29, 2011 Yup, just recolour in what ever post processing software you use... Link to comment Share on other sites More sharing options...

Smeg Posted September 29, 2011 Share Posted September 29, 2011 Ca II K line393 nm -> RGB -> 97/0/186H Alpha line656 nm -> RGB -> 255/0/0Then you can always colour them orangy yellowy.Just Desaturate... then add a new layer FILL with the colour of your choice then set the MODE to OVERLAY and then the Transparancy of that layer to suit.

Macavity Posted September 29, 2011 Share Posted September 29, 2011 Do we know of a nice RGB combo for a (generally perceived) "yellow" solar disk?There seems to be a lot data, for above-atmosphere, stellar classes etc., but... Link to comment Share on other sites More sharing options...
Smeg Posted September 29, 2011 Share Posted September 29, 2011 Can you do it in Pink too? Link to comment Share on other sites More sharing options...
Montana Posted September 30, 2011 Share Posted September 30, 2011 Great image! why not stick to black and white? sometimes colour can just distract us Alexandra Link to comment Share on other sites More sharing options...
