Re: Flats flip

OK, actually also ROWORDER "top-down" is fine.
The problem is ROWORDER completely missing.
Clear skies, Fabio.

Re: Flats flip

Hi, probably all lights, flats and darks FITS files are incorrectly saved vertically flipped, but you can safely preprocess the whole sequence and flip the result after preprocessing. To avoid the problem, you could ask the software manufacturer to support the ROWORDER keyword, see: https://free-ast...

Re: Placing a mark at an exact coordinate

Hello, no, but after the annotation is moved with the mouse, it can be moved precisely with the keyboard with CTRL + arrows. Actually if the point is removed and it's replaced with a star selection, then snapping is possible with the experimental shortcut SHIFT + S (with the annotation active, and a...

Re: Placing a mark at an exact coordinate

Hi, it can be done with the menu command: Image / Select / Coordinates. The shortcut is CTRL + ALT + P.
Another solution could be a script which asks the coordinates then transform them with the command Image.XY(ra,dec)

Re: Coregistering multiple images

Hi, Coregister as a script command and macro command (to apply it automatically on a list of files) will be available in SP3, released in January. To receive the pre-release next week just contact me by email or PM. "Automatic coregister" meant that it was no longer needed to select manually the ref...

Re: Mosaic and rotate

Hi, Mosaic does not rotate. The only solution would be to rotate the second image manually, before mosaic. The angle is the difference between the two images. It could be found via plate solve, or from the same two stars, using the command "Separation" from the Stars Window. For example, if one imag...

Re: Script commands in AA8 SP2

Hello, all the script commands are included in the documentation, but: Image.Stars.fwhmx() and Image.Stars.fwhmy() are no longer supported (because they could not detect diagonal elongation in AA7). They remain in AA8 for backward compatibility, but they are still not reliable. Replace them with Ima...

Re: 2 cameras using same driver

Hi, usually that is managed by the manufacturer with something like "Camera 1" and "Camera 2" in the ASCOM Chooser. Here is a quick example from Atik and QHY cameras: Camera1-2.jpg I suggest to ask the manufacturer what is the procedure to control two cameras with ASCOM. In Astroart, using one or tw...

Re: Plate solving parameters in Telescope control Centering

Hi, everything about plate solving and astrometry is J2000.

If your telescope needs to work in JNow, then enable the options "JNow" both in the Goto and in the Center page of the telescope window. Probably in the future it will remain only one option for JNow, currently that is just a duplication.

Re: Plate solving parameters in Telescope control Centering

Hello, 1) With only 4 stars there's the risk of a false positive. However if the field of view is small, or for some other reason it's not possible to get consistently more stars, there's no choice. The number of stars is different from the Plate Solve window because the Centre window usually works ...
