Re: Shifting a set of images by a given shift (dX,dY) depending on image

Hi, I am at the very beginning of my leaning curve about scripts. So, I have a number of questions ... I would like to shift a set of images (image-1.fit, image-2.fit, image-3.fit, ..., image-i.fit) by a given shift (X, Y)(i), the value of each shift (X,Y) dependant on the image number i. I know ho...

Re: Demosaic - extracting green channels

Hi The command "Demosaic RGB" allows the user to extract a single colour channel. However for Bayer patterns with 2 green channels, does AA8 sum or average these two or just pick one? Regards Andrew The green channels are combined, but I think this is a function of the debayering process itself.

Re: Sun Tracking

I recently tried doing a goto to the Sun but got an error message. Sorry I cannot quote the message since it has been to many days back it was something about format if I remember correctly. Is there a way to do a GOTO to the Sun or is this a safety issue to prevent accidently looking at the Sun? I...

Re: Alt-az mounts

I am curious to know whether others have plans similar to mine. My next telescope setup will use an alt-az mount. While until recently the combination of an alt-az mount and a rotator was the province of very large professional telescopes, it is increasingly available for small telescopes, and thes...

Re: Camera Control Setup tab - Scripts

In the Camera Control SETUP tab, can someone please explain what is the purpose of the Scripts choice? It appears that while an existing script can be selected from the Library, there can only be one recorded? When does such a script run? It appears that to remove that script one must select New? R...

SP4 is an auto installation file where it installs the files in the correct directory for you. SP4 download is an application file not a copy and paste file. It installed fine in Windows 8.1 M...

Re: calibration (dark,Flat & Bias

I'm new to Astroart8. My familiarity with similar software is MaxIm Ver 6.14 and the sky X with which I've found calibration of images fairly simple. 1. Can I create master darks, flats etc that I could load and use for calibration instead of load say the 20 + images taken for each (akin to MaxIM) ...
