Re: 1.8 SVDecon (post1)

but it is ruining my stars. SVDecon pulls a lot of light into the star center. I will illustrate the problem Hi, Pulling light back into point lights is precisely the purpose of deconvolution. Your stars are, as far as I can tell, improved and better defined. If deconvolution works for the rest of ...

Re: Issues with moon glow and aggressive wipe

Hi David, You can, indeed use Wipe on the individual stacks and save them away (while still linear), and re-open them in the Compose module. That said, in widefields like these, you should be able to go quite aggressive with Wipe without losing real detail. The reason for that, is that Wipe works by...

Hi Richard,

The module should behave largely the same. Would you be able to share an image where you are having trouble?

Re: ST, Open, and Bayer Drizzle

Hi Mike, If a Bayer matrix ("Bayered" as the dialog calls it) was used - in any way - during acquisition, this means that twice as many green samples have gone into "the mix" than red or blue samples. This means that - all other things equal - whatever resulting green channel is presented to StarToo...

Also, if you have never came across it in the past, this is from the AutoDev documentation and perfectly demonstrates/encapsulates what StarTools strives to accomplish; https://aife.me/startools-prod-kfsres/modules/autodev/usage/understanding-autodevs-behavior/animation.gif This is a crop of a Hubbl...

Re: The Halos that Aren't

Furthermore, being able to see detailed, consistent diffraction patterns in stellar profiles, yields a lot of clues as to the veracity of detail, focus, and characteristics of the optical train. what can I learn from the diffraction patterns in particular? In the image below many stars have blue "f...

Re: The Halos that Aren't

Hi Ross, It's not so much a philosophy - it's just properly respecting the data, as is the job of the astrophotographer. Clipping (throwing away) or hiding signal is never warranted. Stars are diffracted, single-pixel point lights - they should remain so as much as practicably possible in your final...

Re: Units of bias sliders in Color?

So, if I am reading you correctly, that is akin to the Airy Disk percentage we use all the time in SS. Pretty much. :) Are there any ballparks, and is the slider linear? It's indeed linear. Just kind of wondering what FOV the 50% default is contemplating. And far left, low percentage, would perhaps...

Re: New computer specs??

Hi Wayne, Many cores is always good, but there may be diminishing returns with regards to how things scale and depending on the algorithms you are planning on running. If a chip clocks lower to accommodate more cores, in comparison to a chip that clocks higher, but with fewer cores, then you may ver...

Re: Units of bias sliders in Color?

Thanks again Ivo. That is interesting. So each channel is really adjusted independently. But I presume it is the 3D nature of each pixel that makes it appear that the effect is relativistic. Well, it guess it actually truly is relativistic the way the three channels create final pixel colors. And t...
