Hi, using a Formula it's not possible, but it could be possible with other commands. For example, the task you wrote can be done with: 1) For DSLR and OSC, with an in-memory Preprocessing, selecting "Red channel" as method in "RGB Demosaic". 2) For generic color images, with a script which extracts ...

Hi, to save an image with negative palette, use "Save View" (e.g. JPG, PNG, TIFF ..) To invert the pixels, it's required some pixel math, for example using the Formula: " 65535 - v " for 16 bit images or " 255 - v " for 8 bit. That formula can be transformed into a Macro, to execute it with one clic...

Hi, when making a custom communication protocol based on serial ports, it's easier to test the device with a terminal software (PuTTY, RealTerm, etc.) maybe something similar is already included in the Arduino software. To debug I would start with something like: Lhires = Serial.readString(); if (Lh...

Yes, using a script:

Image.Points.Count

returns how many points are selected.
and:

x,y = Image.Points.Get(i)

returns the coordinates of the #i point.
See in the Guide: Scripts / Function(Images) , "Points and Rectangles" near the end of the page.

Hi, when the Sigma coefficient goes up and up, the Sigma algorithm becomes a classical Average/Add (without Sigma), which gives the best SNR. Sigma is useful to remove hot pixels and satellite stripes, but if these are not present, then Average/Add is better (also Sigma cannot be used for precise as...

Selecting files and folders the command SelectFile let the user to select just one file, and returns the filename as a string. Instead, the command SelectFiles allows to select several files and returns them as an array. It's possible to suggest an initial folder and the extension of the files: fil...

Hello, a new minor version of Astroart 8 is available: Version 8.0 SP6 - April 2, 2024 -------------------------------- * New feature. Automatic meridian flips, with autoguide and centering by plate solving. * New feature. Script commands for selecting files. * New feature. Script commands for persi...

Thanks, may you send me or post a sample image?
Actually it would be possible to deconvolve differently all parts of the image, for example if coma is present. Every corner of the image will be different.

Hello, if the autoguide window is not opened, then no autoguide pulses are sent, so it doesn't matter which "guide protocol" is selected. If the problem really happens when the telescope is connected (just for GOTOs), then try with a planetarium software. If it happens again, it's possible that the ...

New release for supporting the mirrorless cameras: R7, R8, R10, R100. However, these cameras are not supported on Windows 7/8.

If you are using a older camera, there is no reason to upgrade.

Hello, here is a preview of a video tutorial about stacking, and about the option "Follow minor planet", used to align comets and asteroids: tutorial-link.txt The first part of the tutorial is about the basics of image stacking (dark frames vs sigma stacking, hot pixel corrections, etc.). The second...

Hi, the filter is designed to be interactive (the window is non-blocking). Points added over the nebula and/or over the stars need to be removed, selecting a rectangle around them (the filter will update automatically if the Preview Lock is enabled). Sometimes enabling the option "Create flat field"...
