Hi all, I'm trying to de-rotate/stack images in WinJupos but I can't seem to make it work.
I've taken a series of 4 min videos over about 40 minutes and the individual stacks look pretty good (to me anyway). More experienced people than me then take their stacked images and put them into WinJupos to combine and derotate the images which improves their images further. When I try to do this with my images I find that the derotation is not working as it should.
So briefly, I take the stacked and sharpened images, measure them in WinJupos then add them to the "Derotate Images" page. The measured images look fine, the moons line up where they are supposed to, but the stacked image is blurry and the moons (and the shadow) are not on top of each other as I would have expected.
Am I doing something wrong, or am I asking too much of WinJupos?
Example photos are below, the first is an example of one image prior to de-rotating in WinJupos, the second is the image after stacking 8 such images in WinJupos. You can see the faint dots of Europa moving between images, and the moon's shadow forms a dark smear on the planet's surface. The derotate page showing my setup is also here.
Does anyone know what I'm doing wrong here?
Thanks in advance,
