Thanks for taking the time out of your busy schedule for checking the sub for me Ivo. So if I understand correctly, what you are saying is that an individual sub doesn't appear to show any colour discrepancies, whereas the stacked image does? For what it's worth I've attached a fits of a crop of the...

AA also uses dcraw internally (a lot of of software does). Indeed it does Ivo, as does Pixinsight (a working copy of which I no longer have). The only thing is that unlike AA and PI, DSS doesn't seem to work with Fuji RAFs, although it should, necessitating an additional step of converting all the ...

I've now tried stacking with Astroart, with the same result.

Any ideas Ivo?

Hi Ivo, I use DSS for stacking and I've currently a demo of AstroArt. I don't think I can use DSS to crop the fts, after the event, and AA demo doesn't allow me to save. So, I've opened the fts in StarTools v1.4, cropped it, and re-saved as a tiff. Is that adequate? One small bug I've found with v1....

Thanks for your reply Ivo, but I'm struggling with this. The issue for me is that it is such a stark annulus of magenta, trying to rid it by colour balancing ends up upsetting the overall colour balance. I guess that one could start masking but I can't help feeling that shouldn't be necessary. The f...

Hi Here is a crop from the galaxy centre when processed in StarTools. However I work it, I seem to get this pinkish annulus around the bright core. M31 ST v2 sRGB crop.jpg Now my immediate reaction was that this is caused by the bright regions being saturated, but I don't think this is so as the ver...

The output TIFF from StarTools doesn't appear to have any colour profile associated with it. I was wondering what colour space StarTools uses please.

As one of a small number of Alt-Az imagers, using a refractor and DSLR, I'm often surprised that it hasn't gained more traction in the imaging field. It offers an easy entry into the world of imaging with minimal investment, allowing the user to concentrate on and develop the pertinent aspects of im...

+1 for me too. I'm glad the log file is there to allow me to re-do my processing, but it is such a pain. Given that StarTools has a log file I'd been wondering whether it could be saved as a sidecar file or some such, along with the TIFF (or input FITS?), and then used by StarTools to re-perform the...

Thanks all. Certainly the file size seems to imply that, but I had assumed that the DSS autosaved TIFF file wouldn't be compressed, though why I should think that I don't know.
