Hi Everyone -- I used my new ZWO camera tonight with ASILive on a Macbook Pro.   I saved some of the stacked pictures and they're in .FIT format. 

 

Is there an easy way to translate these files into something I can open in Photoshop/Lightroom or another processing program?

 

Thanks!

 

Steve

FITS Liberator is one option.

Thanks.   I've tried to follow the directions on how to install it with a newer OS for the Mac.   It doesn't look like you have to install manually.   I've downloaded it, and then the instruction is to "move the files into the correct locations in the file system".   

 

"Manual install (MacOS 10.11 and later)

To install manually, download the manual installation package for OS X and extract the files to a directory. Next, move the files into the correct locations in the file system."

 

Any idea what that means?

 

Thanks,

 

Steve

Oh darn it looks like it's become a real pain to get FITS Liberator working on later versions of macOS... I haven't used it in a very long time as I work with FITS for my work. Looks like the Windows side is much more straightforward, I don't suppose you have access to a Windows virtual machine?

 

PixInsight is another option, but it's more akin to Photoshop and can do way more than just convert FITS files. It's also commercial software, but they do offer a free trial.

Hopefully others can chime in with other options that are now available since I've last had to tackle this issue!

Actually, IIRC GIMP can also open FITS images.

I believe that AvisFV 2.0 can open fits files and save them in several different formats.

Gimp is free and will also translate FITS to jpg and png.

 

You probably know that your ASI apps will allow you to open and work with FIT files

PIPP is another free option.  I have GIMP as well.  Both work well.

Thanks everyone.   Gimp does seem to work, and I found a $4 app in the Apple Mac store called XISFViewer that also works well.

Attached (I hope) is my unprocessed stacked image of M42.    Gratitude to y'all on this forum that have helped me figure this out.

Just curious why you wanted to open the fits files, as ASILive also saves the stack as a .jpeg which is what I usually look at when using ASILive.

I wasn't aware you could save as jpeg.   Will try that next time I go out.

I think ASILive automatically saves the stack as both  a fits file and a jpeg file.

Upgrade to ASIStudio 1.3 and it has a FITS viewer.

 

Earlier versions might also have had this feature, but I have been using SharpCap and only just noticed this when I upgraded my ASI software.

Yes, ASIFitsView has already been around for a couple of releases of ASIStudio. However, it is only a fits viewer and doesn't allow you to convert and save files as the OP wants to do.

In the latest ASIFitsView version 1.3 one can save in jpg, png and tiff format.

Thanks for that update on ASIFitsView, Roel. The save feature in 1.3  is a welcome improvement to the earlier  versions.
