Re: Stars coloring

Thanks for the prompt reply Fabio.
Well - yes, that’s actually how I do now. But it is difficult to find an adjustment, that fits well for more than one star. Also, for example with M13, you quickly wear up the mouse button ;-)

Stars coloring

Hi, Is there a way to colorize stars that are near saturated in the center? I can do it one by one, by adding a smoothed mask, and then for a red star, decrease the green and blue channels. But for a star rich field, this can be tedious work. Is it possible to automate this with Astroart? Is there a...

Feature request: Connect All button

With mount, imaging camera, guide camera, focuser and filterwheel, it would be convenient with a "Connect All" button, that connected all devices in one go. All devises that were connected last time ;)

Using "Multiscale high pass" on deep sky images

I have been thinking about, how I could get more dynamics in deep sky images with Astroart. Then I thought about the "wavelets" function, as we know from Registax. Wavelets is using fourier transformations to enhance the dynamics in an image. This should also be possible to use on deep sky images? A...

Re: Dithering with PHD2 - setteling issues

Thanks for the answer Fabio - I increased the dithering dx/dy to 6, because I knew that I needed arround 50 frames. But is it ok to have less dithering positions than the number of frames? And yes, my declination has quite some backlash, but I hoped, that AstroArt and PHD could "talk together" and w...

Dithering with PHD2 - setteling issues

I tried the dithering feature a couple of month back, and that night, it worked fine, but it was only for a few frames. Last night, we had our first clear nights for months here in Denmark, so I thought, that I would use dithering for the whole session. My setup: Mount: NEQ-6 Pro Telescope: Sky-Watc...

Re: Applying dark results in dark image

I imagine something like this would do, but how do I save the result in the function createFlats? # Create flats #function createFlats(flatType) rootDir = "C:\1 - ZWO Images\flat\" pre = "#PREPROCESSING" + CRLF flats = FindFiles(rootDir, "flat*" + flatType + ".fit") n = Count(flats) for i = 1 to n p...

Re: Applying dark results in dark image

Thanks Fabio - and Yes, I will try making a script for the job.
I will share it here.

Another thing in the same area; will it be possible to make the sequence window wider?
It is hard to see the exposuretimes if in milliseconds.

Re: Applying dark results in dark image

Hi again Fabio, One question, is it possible to create just a master flat with just the flats? Or do AA need darkflats and darks for the process. Does the three goups have any influence on each other? Can I make master flat only, and then flat darks only and then dark only? I have 100 x dark, 25 x L...
