Re: [APML] Planets on provia 400f
Hi John:
The old compulsion to image those planets on film is still pretty strong,
isn't it? I know I should be trying it on CCD, but .... maybe it's just
inertia plus knowing that setting up the CCD is much more of a hassle than
just attaching the film camera!
I did fiddle a bit with AIP and with MaxIm this evening, but without any
significant results. Not familiar enough with those programs yet. I can get
them to open the tif images, but they seem to want something else done to
them before they will activate the deconvolution filters. If I convert to a
.fit file with Eddie T's Fitplug plugin in Photoshop and then try to open in
the CCD processing programs they claim the header is too huge to work with.
Don't know what's going on there---maybe the plugin is only meant to work in
the fit---> tif direction and not reverse? I may have to try AstroStack
although I already have too many programs on my machine that I don't
understand :-(.
When you were using MaxIm on your planet images, did you load them as tif
files, BMP, or something else? You got a phenomenal amount of detail in your
Jupiter cloud bands! Very nice job!
