Official StarTools support forum

At the risk of derailing this thread about star cores with a post about star cores :lol: 565 is not, it turns out, a super-magic bullet against flat-disk star cores. But I think you have to work at it. How do I know? Last month I started on am M97/M108 project. I took some test subs and pushed the e...

Very nice, Marko! I must admit it took me a minute to figure out what (CVn) meant :doh: The astrobin link says you used an L-Pro filter for this. Any particular reason why? I have a similar amount of time on M3 also this year from my B6/B7 home, but I always shoot clusters and galaxies without any l...

@all: this is ST forum and not Mike's and Dietmar's private chat. :P Participation is very welcome, of course! Shh! Mike and Dietmar are trying to talk here! :obscene-drinkingcheers: (and I want to know more about what's going on in the "obscene-drinkingcheers" emoji) About Mike's question regardin...

Hi Dietmar - interesting project with the plot, for sure. (and absolutely on target for the thread) (I only removed the M13 because my dropbox is nearly full) Here's how I'm currently thinking about it (but I could be completely wrong!) The real action is happening in just the first few points in th...

The answer is that re-calibrating and registering the subs as 16-bit integer files did indeed resolve the 'greater than 1' issue. Which helps explain why Ivo writes signal processing programs and I sit here and push buttons. Here, by the way, is the 1.9.565 version of the M3 data, properly calibrate...

I'm definitely not proposing we should be doing 16-bit stacking, however the assumption is that the source material is *multiple subs* of 10, 12, 14 or 16-bit quantized data, where values fell within the range of 0 to /1024, 4096, 16384 or 65536. Stacking multiple subs will - in essence - add 2^(st...

Colors! Now we're talking! Can you do one with 8x10 color glossy photographs, with circles and arrows and a paragraph on the back of each one?

Link to the raw single sub - https://www.dropbox.com/scl/fi/gdnc1l46c8eihc6lqwe21/M_3_AT130_45s_Light__336.fits?rlkey=sxv03qpaepnpzhm2gh061tc0t&dl=0 although it probably does not matter any more. I think 16-bit ADCs are now fairly common, with the IMX571 having become so popular, though maybe that's...

I was also able to "hide" it by increasing Optidev's curve resolution (the amount of points it calculates to interpolate the constructed curve between) 16-fold (from 4096/12-bit points to 65536-bit points), which should not be necessary unless something has stuffed lots of data/"detail" in a tiny (...

What Mike said - thank you, Ivo! Haven't had time to do much beyond download the new beta yet, but a quick look seems similar to Mike's reaction. Different, but definitely improves (cures, even?) the dark-ring effect. As for 16/32, it's a bit awkward in Siril to keep swapping back and forth (really,...
