Thank you. Improving the results from all algorithms in ST will always be high on the agenda, so it may well be that I can find a solution for more difficult cases. And, of course, if the WPs are the result of bugs (rather than a "misinterpretation" of the data by the algorithms), then these definitely require fixing with high priority before we can make it to beta/release. There is plenty of scope in the algorithms for those bugs to creep in (for example as @Mike in Rancho and @jackbak have shown me).firebrand18 wrote: ↑Wed Sep 15, 2021 2:26 pm @Ivo, you hit the nail on the head with "It is perhaps worth mentioning though, that normally Deconvolution is extremely sensitive to noise or artefacts and singularities (such as over-exposing star cores, or hot/dead pixels, etc.)." That is probably the crux of the problem in my case as shooting from a Bortle 8 where noise and other spurious junk makes its way into subs, even with narrow-band filters (I use L-Extreme).
In a heavy nebula image (currently processing the Tulip) good luck trying to select clean sample stars; never mind WP, I get deformed stars no matter how I play with the settings. Have to resort to synthetic decon in these cases, which still does a pretty nice job with deconvolution. Had much better success with my Glob images using SVDecon with only 1-3 WP's, easily healed out.
Your system is most definitely supported, and should yield a nice speed boost in most cases. You just require drivers that support OpenCL, which you should be able to obtain from nVidia's website.On the subject of 64-bit GPU (any version); I cannot launch it; assume because my Nvidia GTX-1060 6MB on a pretty powerful Intel i7 PC is not supported? If so, any options; I feel left out!
Just FYI, $400 US for an RX570 is excessive, even in this climate. Depending on how recent your distribution is, Linux will support most AMD and NVidia cards. However, you will, at the very least, still require to install the vendor's proprietary drivers, which will enable OpenCL support.jackbak wrote: ↑Wed Sep 15, 2021 7:17 pm I am about to pull the trigger on a moderately priced (for today's bloated prices) used AMD RX 570 as I have been told that AMD drivers are built-ins for
linux. I sure hope this is not a waste of $400 US. I just can't redo my complete computing world for Kubuntu - I do everything from banking to astronomy in linux, there is no Windows in my world.
If you are buying second hand, it will be much more cost-effective to go for a card that crypto miners don't want (the RX570 is rather popular with them because it is a fairly low power vs high hash rate card).
I currently run an eight year old AMD R9 290X under the latest Linux Mint (was a little bit of a hassle to get the card working though). It's about as powerful as an RX570/RX580, but draws a lot of power when processing. If going for an older card, just make sure your power supply can handle the power draw.
A new GTX 1650 Super should also be possible for around than $400 USD, which performs better than the RX570.
Hope any of this helps!
