Re: The Halos that Aren't

Hi, the post at the top of this page said the image was NB and merged with RGB stars too so not a OSC source. Hi, I think Stefan should be the one to answer this, but it just so happens that I have had some discussions on this topic before with Stefan, we discussed this subject because his imaging ...

Re: The Halos that Aren't

Hi, I have a question relating to the below: With the image at hand, I cannot readily observe detailed diffraction patterns (which is a useful cue in itself!). At full resolution, there appears some blotchiness to the outlines of stars, and it is clear the stacker was unable to properly align the tw...

Re: The Halos that Aren't

Hi, following with great interest. I have exactly the same imaging setup as Stefan, and very much the same issues and questions.

Re: Star Tools GPU processing - GPU type influence?

Hi, I did the testing with as similar conditions as I possibly could. I did as follows: * Start Star Tools * Open the image * Go to Deconvolution, select "Mask as is" (full mask), start stop watch * Stop the stopwatch when done. Repeat from start at least three times, calculate average, and then cha...

Re: Star Tools GPU processing - GPU type influence?

Hi, Thanks for the tip, this worked, I could choose which GPU was used this way. This also gave me the oppurtunity to test the processing time when changing no other factors than the GPU. So I did a simple test, I ran deconvolution on a 4466x2940 32 bit FITS image. I did three processings with each ...

Re: Star Tools GPU processing - GPU type influence?

Hi, thanks for your answer, I now have a different machine, a gaming type laptop that has both Intel UHD 630 Graphics and Nvidia GTX 1650 Graphics. However, Star Tools states that is using Intel UHD 630 Graphics, and so it would seem that the Nvidia graphics is there to no avail for Star Tools...? R...

Re: Star Tools GPU processing - GPU type influence?

Thanks for your answer. The GeForce 1030 I have is specified to have GDDR5 SDRAM memory. I am not really considering to buy a separate GPU, rather I am choosing between different types of laptops, either a "standard" one with only integrated GPU, or a "gaming" one with a dedicated, but preinistalled...

Star Tools GPU processing - GPU type influence?

Hi, I have a question relating to Star Tools GPU processing. I did some testing on the time gain of using Star Tools with GPU support, and without it. I measured the time needed to do the default deconvolution processing on an otherwise unprocessed image. My result was that when doing the processing...
