I've been looking for a software to get a FITS file and export 1 file for each of the RED, GREEN and BLUE channels. I came across Nebulosity last week, but I can't buy it's licence since I live in Iran... I'll be grateful if you introduce any similar applications...

I think the requirement to use a specific scientific data file format may move this to being off-topic. But, you might look at ImageMagick, which I believe has support for this format and which definitely can split an image by channel. –  mattdm Jul 29 '13 at 20:53

This question appears to be off-topic because it is about a specific need for results in a scientific data format. –  mattdm Jul 29 '13 at 21:05

You can use Raw Therapee, it's free.

Almost every other software have this feature, Photoshop, Coral Paint Shop Pro and much more. just pick one.

In Paint Shop Pro You go to: Image -> Split Channel -> Split to RGB. Simple as that. In photoshop it should be the same.

Edit: Since spliting TIFF format does not help you I suggested an edit to your question.

I know, but they don't support FITS format. –  Ali Sadighi Jul 29 '13 at 20:32
    
I don't know about FITS, but TIFF is definitely being supported in all the 3 softwares I mentioned. –  Itay Gal Jul 29 '13 at 20:36
    
Yes, that's right. Thanks anyway. –  Ali Sadighi Jul 29 '13 at 20:38

You may consider FITS Liberator, which is a software developed by NASA and ESA.

It is also free and was built to support a number of astrophoto formats.

It's available here: http://www.spacetelescope.org/projects/fits_liberator/

Should be available for download for your region.

If you want to buy software, I highly suggest PixInsight. It's what I use. Liscensing is based in the EU, so it may still be a challenge for you.

Thank you, well I actually am using FITS Liberator for other purposes and not for dividing the channels. I think what mattdm said can do the job. ImageMagick... –  Ali Sadighi Jul 30 '13 at 12:45
