[AZ-Observing] Re: Very Good Seeing and Another Saturn Image

Tom,

I am not a state of the art imager....I use a Nikon DSLR just like I did
with the "old" film cameras, sometimes I get fancy and try to stack a few
iamges.

Nothing like what you did.

I was just curious as to how you took the image.

Thanks for the information, the image is great.

Tony

Tony,

I gave talks on this subject at both big Phoenix clubs.  It's a stacked
image using a monochrome camera with R, G, and B filters.  I do 1000 frames
(or more) in each color channel.  Since Saturn is faint in a 10-inch, I can
only use 15 frames per second.

If you want to learn how to do tri-color image, it's hard to do better than
Mike Salway's tutorial.

Tom,

Another great image of Saturn.

Are these images a single shot or a stacked image??

Can you give some details about the exposure data.

Happy New Year to you and Jen.

Tony

I got up again at 4:00 to do a seeing check, hoping the result would be a
return to bed.  But no, there was only a bit of image motion at 300x. I came
away with a much better image of Saturn than yesterday's.  Notice that Titan
has moved to the east of the planet.

Still need to mess with the color balance, or are the edge-on rings really
that red compared to the disk?
