Auto extract of three colors at once

[John Sikora]

I saw the comment in the last version history about being able to extract RGB in one go. Where is that in the menu? I may be just blind but couldn't find the option.

It is in the popup menu of the photometry tab. See attached.

Remember you have to select the files first

Thanks, got it.

Hey !

I dreamed about this very useful function a long time ago (in a far galaxy) ... And you did it !
Thank you sooo much, Han ;-)

Thanks, but note that the stars have to be unfocussed to some degree, to measure with 1/4 of the sensor area in red and blue. If the sharp peak of a focussed star is at one of the green pixels you will not measure very accurately red and blue. On the other side of the range, a too unfocused star will result in star detection failure.

Hello Han,

Thanks for the tip. Indeed, I allways capture images in a defocused mode, and have almost no trouble to solve the images and finally get good photometric results.

Unfortunately, when observing some bright to very bright stars, I need to severely defocuse (20 to 50 and more pixels in diameter for the star images). This conduct in impossibility to solve the plates, so It is need to extract the data manually. Not a big deal, and a reasonnable and acceptable price to pay for an otherwise usefull and very good software, which makes life much much easier . ;-)
