Re: Astroart 7.0 SP2
Great, I assume that this is the first exposure of the night (?) If not, for autofocusing during the night, the Step must be lower, because the defocus must be much lower. I'd say maximum 50-100% of star size, for example, if the good focus for your system is stars of 4 pixels then the Step must be ...

Re: Applying dark results in dark image
Hi, master darks cannot be done with "Sum" methods, it's required to use the "Average" methods, otherwise they will have a diffent scale compared to light images.
With that dark frame you can solve dividing the image by 50 then saving it.

Focusers and Rotators in SP2
Hello everybody, Astroart 7.0 SP2 has several new features for these devices. The focuser temperature can be used as ambient temperature and written in the FITS Header: AmbTemp.png During autofocus the results are drawn as graphs in realtime, both in the subframe and in the fullframe autofocus: AmbT...

Re: Save "Points" used for gradient removal
Hi, on the other image, just SHIFT+Click to copy and paste the points.
SHIFT+Click can also be used to recover deleted points on the same image. Other functions are described in the Help, paragraph: "Selected point".

Re: Preprocessing error
Yes, two separated stars, for example near the corners, but not too close to the borders. By the way "two stars" is useful only if the image have rotation too, maybe "one star" is sufficient for those images. Try a comparison of the result. A bit of saturation in the center of the star is not a prob...

Re: Preprocessing error
Hi, the problem is big saturated stars, for the moment the only way to solve is to use the align method "One star" (or "Two stars" if you want to correct rotation). Procedure: 1) Before launching the preoprocessing, open the first image, select a star (ideal is a medium bright star, isolated, eg. wi...

Re: creating Hubble palette
Also, if you need to create the frame which is 70% HA and 30% OIII , it's possible to use the "Merge" Window or the "Average" Window, after having aligned the images with the command "Align" or "Align All".

Re: How to specify FIT format?
Hi, before saving, menu Edit / Data format / Floating point.
In the status bar of the image the range "R = ..." will be expressed as "RF = ..."

Re: Scripting functions for stacking?
Hi there's an experimental command called "Preprocessing(text)" which accepts a text which contains the files to be stacked. Here is an example of the format of the text: #PREPROCESSING Dark=D:\temp\Drk01.fit Dark=D:\temp\Drk02.fit Image=D:\temp\IC1805-R1.fit Image=D:\temp\IC1805-R2.fit Image=D:\tem...

Re: GSC Data - No SAO labels will DIsplay missing Stars
Hello, the GSC catalog is on the Astroart 3 CDROM, in the folder "GSCData", just copy it to a folder of the hard disk. In the past, the USNO A catalog must be requested from the USNO headquarters. Here it seems that there's a FTP folder to download it: http://tdc-www.harvard.edu/catalogs/ua2.html . ...
