M31_2.jpg Guess i got it out..took about an hour with trial and error. I also reduced the starfield a bit, needed a mask for both M31 and M101, to keep untouched, otherwise i lost too much detail. Trouble is for very cluttered starfields this seems really difficult. In this case it worked pretty we...

Thanks alot Ivo, Really appreciate this. I will recheck me DSS settings, guess i missed background calibration setting i noticed. Last picture is really great! Strange i winded up with that many stacking artifacts, allthough this fall beyond the scope of ST. Some CN members reported also quite some ...

is this to be expected Hi My guess is that wipe should be able to flatten the colour better if you cropped the bottom edge a few pixels, but unless you post -a link to- the original file, it is just that; a guess. Cheers and clear skies, Steve Indeed there were quite some stacking artifacts , still...

Still confused witht the wipe function.

After wiping, and choose the color button i get still this , see image

Can't understand why.

Found that i had to reduce the gamma button an eventally got a descent image, but is this to be expected, is what i wanne know...

Tried it also today, Got confused with M31 as it gave me real bad overcoloured and oversaturated image. Eventually was able to drop somewhere the gama ray and that it all fell into place. I have a hard time processing images...but sofar Startools was able to producs nice images, though i wonder if i...

Then i have to download it immedately as my M31 looks exactly like the picture on the right....

I did not figure it out...that is why i used the develop stretch , to at least give me something...

White balance is off.

I followed the guidelines in found in the ST 1.6 manual for stacking. Still in dev image comes out B&W until i add color to it...Do i overlook something...?

Yes i crop and wipe. But meanwhile i think i figured it out, I have to use the second option when you load an image , linear bayered etc...not just linear If i then autodev, i get a black and white image , but thisone shows me actually the defects, like gradients or edge distortions. After cropping ...

Hi everybody, I having some trouble getting an good image out of autodev... At start i get a very red background with eg a very yellow M31, or really blue background with a yellow M100. What is the exact procedure ? Use autodev : correct issues - like gradients - crop edge stacking artifacts... And ...

Great info, I will try out ST 1.7, because my old computer has a GPU. Yesterday i tested ST 1.6 and GPU remained pretty much in an iddle state. I will replace my current setup because it belongs to my son and allthough not that bad it is over 7 years old, but still rather powerfull. Off course syste...
