Subject: Re: [Astro_IIDC] Saturn with 4 moons

Hi Milton -

I really like your picture! Wonderful how the turquoise color of the northern tropics shows up at this image scale.

I happened on a fantastic saturnian moon alignment last week viewing on January 18. I could only make out four strung out in a perfect line with the planet's equator, but after checking Starry Night to identify which was which I found that Mimas and Enceladus were there too. I wish I had imaged at a short focal length to record it as you have done. The seeing wasn't too bad, but I had a very difficult time with the wind and low transparency. Completed an image this morning:

Thus far this is the only data I've recorded this apparition worth wrestling with - and it is almost opposition already!

Hi folks;

I finally got my HEQ5 mount drift aligned last night after bringing it

back from my Christmas vacation trip.

Since Saturn was above 30 degrees when I finished, I tried imaging it

at prime focus and with a 2x barlow too. Turublence was a little bit

better than average, but still I captured nothing worth posting (or so

I thought).

However I could just make out Titan in the prime focus images (shot at

30 fps), so I log stretched them and much to my surprise brought out

three more of saturns moons (Mag 9.5 to Mag 10.2).

This image is all one and saturn is not pasted into the image like

I've done in the past. I just log streched it bring out the moons and

left the structure of Saturns rings in it.

TTYL..
