Re: calibration (dark,Flat & Bias

I suggest to test incrementally: 1) Add your images to the "Images" box, verify that no options are active and press OK. You should get a result image with trailed stars and noise. 2) Enable auto-alignment in the "Options", press OK, the stars should now be round, but noise will be still visible. 3)...

Re: calibration (dark,Flat & Bias

Hi, 1) Yes and it's recommended. However using Master dark frames and flat fields is just a speed optimization, which will save 4-5 seconds for every process. Before doing that, verify that the results you are getting are already correct. Then, a Master file can be created "manually" placing dark fr...

Script commands for sequences

Astroart 8 SP4 has some new script functions to create a sequence of images. Try the following example after having connected the Camera Simulator: if Sequencer.Active then print "Sequencer already running" Script.Stop end if Sequencer.Clear Sequencer.Add("Light", 3, 10, 1) Sequencer.Add("Dark", 2, ...

Re: Astroart 8 SP4

further information from the updated documentation: Optical distortions with user defined polynomial order ... use the option "Distortions between images" only if the images cannot be aligned well by normal rotations. This can happen with large fields when the images were taken on different nights o...

Re: Full Frame Focus Exposure Time By Filter

Hi Joe,
you may switch to SP2 / SP3 , using the SP3 Upgrade: https://www.msb-astroart.com/down_en.htm
but I think that nothing will change.

Maybe you are now using the 64 bit version? Maybe you upgraded the QHY ASCOM driver and now the device names are called: QHYCCD-Camera and QHYCCD-Guider?

Re: Starnet path

The setting is saved into the "Temp" folder of Windows, so it's possible that if you "clean up" the PC it gets deleted too.
In a future release it will be saved into a more persistent folder.

Re: Full Frame Focus Exposure Time By Filter

ASCOM relay boxes are rare hardware which converts USB/serial to an autoguide cable, it's probably not the correct settings. If there is no need to control the mount for GOTOs, I confirm that the correct setting is: "Camera 2 relays" / "Same connection of GOTO" or "ASCOM guider relays" / "Same conne...

Re: Full Frame Focus Exposure Time By Filter

... Looking at the full frame focusing window in AA8 there isn’t an option to set the exposure duration by filter (I.e. 3 seconds for LRGB filters and 30 seconds for the narrow band filters ... Until now it's only possible with scripts, but that's actually an interesting feature. It will be added t...
