I am trying to get a grip on winjupos derotation. Having troubles. Last night I managed to get about eight shots of Jupiter as the spot transited. I read that you can set up firecapture to make a text file that winjupos can read so you don't have to manually put in the time and date and location, but haven't figured out how to do that yet. I manually entered the times for the images and combined and came out with this result. Does anyone know where I went wrong?

Make sure all the checkboxes I have circled in Blue on the follow figures are checked. This will create a text file with the same name as the capture file.

The only setting above that matters is the "Winjupos file naming".
The text file is totally irrelevant. Winjupos tries to parse the image file name and if it looks sensible, then it uses it for the date/time parameters.
The date/time part of a FC filename represents the mid-point of the capture.

might set LD compensation to .5 if you still have problems
or at least tweak that setting to see what works for your image
you can try this iteratively in the derotation section

thank you both! I set my firecapture up so that will help a lot. I turned down the LD to.5 and got a better result. I still see artifact, but Im heading n thr right direction.

Lowering LD (limb darkening) can be beneficial but it is really just masking inaccurate AF (alignment frame) setup &/or incorrect timestamps.
Flick me a PM with an accurate email address if you'd like my WinJupos tute. (it is too large to PM)
It is quite old now but is still a good complete guide for using WJ, with occasional updates.
