Official StarTools support forum

Hi Freddy, this is what I came up with: IC410_Freddy.jpg Disclaimer: I have absolutely no experience in processing mono/SHO data sets nor data coming from refractors. My first thought was: "Where are the spikes"... This is a pretty straight forward processing. No fancy stuff. SHO matrix was one of ...

Thanks Mike for trying, Yeah a real pity of the framing. When i first noticed it, i felt like slamming myself. Alot of the otherwise beautifull surroundigs are a bit lost. And yes it comes out a bit muschy in Startools, doesn't it. Splitting the image in starless and stars and using unscharp mask fo...

Here is the link to the files https://www.dropbox.com/scl/fo/kuqrdpj5wnsg6nntf67io/h?rlkey=kknxdzvudhiags4y3jk975ftl&dl=0 Anyone who likes to process them, most welcome Be aware , the second stack is too much tilted...i loose quite some field there, unfortunately... Mike in Rancho Stretching in PI i...

Ok , well not 100 percent Startools but let's say 95 percent. I did the complete run through Startools. But i could not get it sharp, not sharp enough to bring out the details. So i use PI and use Starnet 2 to create a starless image, and a starimage. Then in Gimp i used Unscharp mask , that worked ...

Beautiful Stefan.

As i allready mentioned, very nice starcolors. Startools is really good in that imho.
Finally we has some clear nights over Europe...giving us some slack to image, it has been ages. Sadly , it is allready over

Mike, That is quite nice, imho. I really like the difraction spikes on the bright stars :thumbsup: , i think they add value to the picture. It could perhaps use a bit more integration time just to reveal a bit the darker clouds under the horsehead. Certainly a target i want to revisit too, allthough...

Hi Mike Yes the holes are still there, more in the background but still there. They come from starremoval , i am almost sure, i think from the PI script i used here. I must do further investigation, cause there are several parameters in the script. Still i find it acceptable, but too much enlarged i...

Mike in Rancho i made a new one. Almost completely done in Startool, i do say almost bin 50 percent stretched, wiped hdr contrast NO sharpening Deconvulation, classic Full color -SII reduce bias to 0 - Ha bias reduce to 2,98 - OIII bias reduce to 0 - Matrix : SHO 50SII+50Ha,50Ha+50OIII,100OIII entr...

I like your most recent rendition on astrobin, Freddy. When you are using star removal you are probably doing that in PI, right? Is that on linear data or already stretched? Can you then process in ST with tracking on? Regards Stefan Thanks Stefan, Yes, star removal has been done in PI on the secon...

Do you see that, too? That looks strange to me, I’ve no idea what’s causing it. Some kind of correlated noise? Grain size is much too large to be normal shot/Poisson noise. Is this already visible after stacking or does it happen later during processing? Best regards, Dietmar. I guess it comes from...
