Once you open it in GIMP, you can EXPORT AS and select TIFF. There are many other file types to choose from. Also either in GIMP or Photoshop you should change the MODE of the file to 16 bit RGB. It was 32 bit Grey Scale which as you saw has few options.

Anyway after you save as TIFF you are off and running to do whatever Photoshop magic you can.

Hope this helps :telescopewink:

It actually does, thanks :D I wasn't too sure if doing the conversion to 16bit RGB was just adding color to greyscale. I tried it doing that and it seems fine in PS. Thanks again!

All the best,
Mark

First off, I have only done AP with the Sun/Moon, so any processing from me would be, well, bad... :lol: But I ran into the same thing JT did.

I downloaded the file, and first opened it with Gimp, as it was the only thing I had that reads it. It opened... in greyscale. And as you can see in the colors tab, the options are limited.

Hello Mark.

When you first open an fts file in Gimp a box opens with various options. The bottom option defaults to greyscale (can't remember what it is, I'm not on my laptop!) if you change that to Naxis 3 (Dunno what that means!) the file will open in colour. At the top of the screen a couple of file thumb nails will be displayed, select the black one. Then click the Curves command from the Colour Menu and stretch the curve up and to the left. Try experimenting with different amounts and from different positions. Then, as if by magic, an Iris will appear! Then after messing with Levels and other functions, Export as a png or jpg and post up the result.

Good luck.

Regards

Graeme

Excellent detail in the Iris and the black nebulosity shows up well too Andy.

Adobe CS2 does a good job. Would you say it's a step up from Gimp or on a par?

Regards

Graeme

Hi Graeme I used to use gimp,but I find I get on better with Adobe cs2 and was free to download.I also use deepskycolours and I paid for anstronomy tools that I use for the plugins on Adobe cs2,also the deepskycolours works in affinity as a plug-in,only paid £23 for affinity as was on promotion.Thats all I use,as some other software is expensive.
Thanks

AP Processing Challenge No 5 is now closed.

A popular challenge, 9 of us had a go at it, experienced and beginners alike. So a big thank you to BobHarmony for the data, NGC7023, the Iris Nebula in Cepheus.

Don't forget AP Processing Challenge No. 6 is still running. An excellent opportunity to have a go at processing an image of Comet C/2020 F3 Neowise with data submitted by GCisko.

The next one is AP Processing Challenge No. 7, starting today, which will be a chance to have a go at processing an image of M57 the Ring Nebula in Lyra submitted by me! Come and have a go.

If anyone would like to submit some data for a future challenge please send an email with a link to your data to tssapchallenge@theskysearchers.com. Feel free to PM a Mod if you would like further instructions.

Regards

Graeme
