I know I am
crazy – only a little over a week after my jaw surgery, and I’m back outside! But the sky was clear, and I couldn’t
resist! I wanted to try out the ZWO with
Saturn. But first, downstairs neighbor
Rhonda’s grandkids were visiting, so we looked at the moon, Saturn, and
Jupiter. The seeing was pretty decent,
but not spectacular.
For
imaging, I used Miqaela’s five-slot filter wheel, since I’d found the piece I needed
to attach the camera. The B channel
looked fuzzy, so I re-focused and tried again.
I took 2-minute videos on each channel.
I had to use VirtualDub to convert them to an AVI format that RegiStax
likes, but it took it then without complaint.
I followed some instructions online where you process each channel, save
out a FITS file, and then stack the three FITS files. You just have to add _R, _G, and _B to the
end of the filename (or also _L if you do luminance), and RegiStax will color them
appropriately for you. I ended up not
using the L channel because the result was weird. It worked great, and the result is awesome!
