Apply the color module to each stack before switching Tracking off for each stack. Take note of the red, green and blue ratios. If all is well, they should not vary much between stacks, but it's probably a good idea to stick with the same ratios. You have oodles of detail in there, but I do notice t...

Hmmm... that's odd. Could you perhaps share the data (or a crop of the data) and your processing log? It would bemuch appreciated!

besides being out of synch my resulting short image is darker than my resulting Long, Hmmm.... Isn't that to be expected? Could you maybe post the two results as a jpeg in this thread? Scratch that... I just saw your images. The issue is simple; you're not suuplying a FIlter Kernel radius! (play ar...

If I were to find a way to crop the files together in Nebulosity, in order to synch them and make them the same size, would that make my files "non linear", and mess up their use in StarTools? It shouldn't - making data non-linear pertains to the way brightness livels pixels are non-lineary tranfor...

Hi Tom, Aligning your data sets is something that fits more in the realm of pre-processing. If you're using DSS you can use one stack as a reference frame to align the others against (without using the stack in the stacking result). Could you tell us your processing flow? You should be able to arriv...

Awesome!

Ok, cool. I'm having best results with 9.17 - a later version introduced a bug (can't remember the issue exactly... ).
Very odd about the wildcards not working...
Does the option '-t 0' (flip image = none) help with the auto rotate?

Thanks Rowland. Will try to repeat this.

Expertly processed and such a good example of a target that benefits from the Color Constancy algorithm. Hard to believe this is from a DSLR. Glad you discovered the read noise compensation parameter and find it useful! It can really clean up a background that has been overstretched to show mainly r...
