Saturn 2008

Here are some more Saturn shots I took on February 10th thru 13th. 

Saturn two months from 2008 opposition

Saturn on 4-22-2008, notice the rings are more open

RGB Taken on 5/3/08, ring color best

I tried to imitate the color on the Cassini Saturn pics, this is similar to ring color

RGB Taken on 5/3/08, planet color is best

Not sure why the rings appear yellower but in some NASA pics they do too.

(RG)RGB taken on 4/22/08, more blue

Still trying to get the pastel color with the white rings

The seeing was pretty good. Notice the storm in upper right.

Not great seeing but came out pretty well, near opposition

Rings are fairly closed right now but no shadow from the planet on the rings

These photos were taken on 1-27-08 (my dad's 75th birthday).  The seeing was pretty good but I had some transparency issues.

Picture was enlarged from original. Taken at f/10.

First good shot of 2008.  I might have some others but this one is first out of the chute.

For the moon lovers

The Enceladus and Tethys moons were copied from Dione and placed according to lum only shot

Taken 2-13. Comparable to LRGB pics. Seeing and transparency were pretty good.

I worked on my technique for RGB images and, as opposed to what I was able to do with Mars, Saturn shows about the same in RGB as LRGB.  Hmmmm...

Less gain on this image. Colors a bit different.

Saturn on 2-13 using Powermate 2.5x
lrgb-c775g105in0049-08-02-1.jpg
Saturn is near opposition in this shot.

The picture below was taken without using the Powermate.  The Powermate magnifies the image 2.5 times but, consequently, it's a lot dimmer.  If the atmosphere is still though, you always get better results using the Powermate even though your picture acquisition times are longer.

This is an LRGB full color shot taken on 2-10-2008 using no filter, red, green, and blue filters.  It is still odd to me how pictures taken on different nights can look so different.  Some of it is probably humidity in the atmosphere, elevation, pollution, seeing, transparency etc. but some of it is probably the way I do things.

Here is an LRGB image of Titan, Saturn's largest moon and the only moon with an appreciable atmosphere.  I used the 2.5x Powermate to give it some size and took away some blue and a little green from the final image.

Here are the smaller visible moons of Saturn.  Titan was quite far away on this night.  The one off by itself toward the bottom is Iapetus, the mysterious black and white moon.  It was lucky to have it so close to Saturn when I took this.  The others, from right to left are:  Enceladus, Dione, Tethys, and Rhea.  It was taken on 08-02-11 at around 05:35 GMT.  These are just monochrome shots.  It's hard for me to get the little guys in color.
