Pixel processing in SP6

Hello, as written in the post about the release of Service Pack 6, some new commands have been added, and all the "GetPixel" and "SetPixel" commands are now much faster to permit image processing and analysis in scripts. Image.PrepareUndo Image.Undo Image.GetPixelR(x,y) Image.GetPixelG(x,y) Image.Ge...

Re: combining 1x1 lights with 2x2 colour

Hi, you can combine steps 1 and 2 with the single command "Coregister", which scales and aligns. If it's not possible to align automically, Coregister will ask you to select three stars (or three points) on both images. The procedure is: select the RGB image, click "Coregister", the select the L ima...

Re: Difficulties to remove subtle gradients

Yes, a darker UI will be added in the future. Meanwhile the Full Screen window with its black UI can be used for some tasks: press CTRL+F12 to show it, then: [+] (Numeric keypad). Zooms in the image. [-] (Numeric keypad). Zooms out the image. [Arrows]. Pans the image. [PAG_UP] , [PAG_DOWN]. Changes ...

Re: autoguiding query

Hi, about "reduced the pulsing", which option exactly ? By the way, I suggest to reset all autoguide settings (click the 3 buttons "Default values") and repeat the calibration (is it normal that RA is 2X faster than DEC?)

Reliable autoguide with scripts

Hello, I've been asked the most reliable way to command the full-frame autoguide from scripts and to alert the user after 3 images with autoguide lost. Here are the functions that are currently used: This is the subroutine to start the guide: Function StartAutoGuide Guider.FullframeAutoguide guideOK...

Re: Trying to quantify seeing/image-quality

Try the option "Confirm all images" with the option "Multithreading", prepare the left hand on the ESC key and the right hand on the RETURN key, usually it's possible to select/discard manually images quite quickly, I'd say that 300 images can be selected in 200 seconds. The options for automatic re...

Re: Trying to quantify seeing/image-quality

Interesting! About the questions: 1) There's the command Image.RaDec(x,y) which could be called for two adjacent pixels. 2) The command Image.FWHM uses the 30 brightest stars of the image, so it could give a different result if compared with 500+ stars. Maybe it's better to exclude also the faint on...

Re: Platesolve fails near celestial NP

I checked, you're correct, plate solve is not possible near the poles (Dec > ~89). It will be fixed in Service Pack 6 available next month. The problem was indeed the singularity of the pole coordinates.
If you need the prerelease now, let me know by email or PM.
Thanks, Fabio.

Re: Plate Solving Failure

OK, but I suggest to don't change the rotation tolerance and leave it at +- 180 degrees. You may decrease the rotation tolerance only if the camera is aligned with the equatorial axes. The exact field of view is 43.2 arcmin, it can be found with the Statistic Window on a calibrated image, so the set...
