Thanks. I checked the help menu, and found nothing. I now realize that I hadn't installed SP6 yet... :)
:D - do You know where to download it from?

Re: Script commands for domes

From the help: Dome functions Dome.Connect Dome.Disconnect Dome.Connected These functions are intended for connection with the ASCOM hubs, for example "POTH" or "DeviceHub", where the movement of the dome is controlled by ASCOM. Your scripts will just open or close the window, or park the dome. Exam...

Re: Feature request: scale bar on images

Hi Bernd - I would also like to have this available somehow. Perhaps as an extra annotation type, that You can place anywhere in the image, and that automatically add/remove tickmarks depending on it's size.

Re: Pixel processing in SP6

Thanks Fabio. I will proceed with the one dimensional array. Just wanted to ask first ;-)

Re: Pixel processing in SP6

Hi Fabio, This is great. Is it possible to define a two dimensional array in the scripting language? I've tried: dim(640,480) dim(640;480) dim(640:480) dim(640)(480) (...and many more), but with no luck. I need to store the image bits in an array in order to subtract one image from another in a scri...

I controlled two Canon D1000’s simultaneously with two AA instances a couple of years ago with success.

Re: autofocusing noobie q

I do not usually autofocus for every image, but perhaps every 5 to 6. AutoFocus takes arround 30 seconds on my setup, so doing it every 120 sec image, would "waste" 25% observation time. Doing it every 6'th image, only 4% observation time is lost for focusing. I always let Astroart save focus pos an...

Re: Trying to quantify seeing/image-quality

Pascale,

If the star is elongated at an angle of 45°, 135°, 225° or 315°, then |sin alpha|=|cos alpha| and Astroart's x and y components are equal.

Re: Trying to quantify seeing/image-quality

Hi @pask, Thanks for the formula. That's a clever way to give one single value for an image. I have also been searching for such a formula. I wonder, if it is possible to get the "true" elongation with a script function, perhaps even also the angle? Not just the x and y components. If the elongation...

Re: Trying to quantify seeing/image-quality

Hi again Fabio, I am still using my analysis script, most recently on almost 600 images taken over several nights - it would be an almost impossible task to go through all images manually one by one. Here's the output put into an excel sheet, showing the background levels. I use this to quickly dete...

Difficulties to remove subtle gradients

Hi, Yesterday I was processing an image in Astroart, and when editing the image, I could not see, that there were a subtle gradient on the right side. I think, this is because Astroart is so bright, when viewing the full image. Then my (old) eyes cannot see the gradient in the dark image, it drowns ...
