Curious Saturn image
by Chuck Hards 30 Sep '04

30 Sep '04

http://saturn.jpl.nasa.gov/multimedia/images/raw/casJPGFullS04/N00019699.jpg This image was obtained Monday, Sept. 27th. Note the trailed stars behind the tenuous "F" ring, as the camera tracked the rings during the exposure. Does that mean that all the untrailed points are discreet ring particles? They vastly outnumber the trailed stars, and obviously cannot be stars themselves...or do I have it reversed? Are the brighter, trailed images the ring particles, and the dimmer ones stars? I don't think so; I think we are looking at individual ring particles, the first time in history other than "shepherd moons". Can a lister more familiar with the details of the probe help solve the mystery? _______________________________ Do you Yahoo!? Express yourself with Y! Messenger! Free.

Just for the record, a good friend of mine had his family's house burn down because his sister left a small "makeup mirror" on her bed where the sun hit it. I don't know how common such a thing is, but apparently it happens. --Paul

Spaceship 1
by Debbie 29 Sep '04

29 Sep '04

I turned on CNN news this morning just in time to see the civilian Spaceship 1 rocket into space. It was anything but routine. As it went vertical it started rolling wildly and kept on rolling as it entered space 62 miles above the earth. I held my breath as the skilled pilot regained control of the craft and I watched it land safely at Edwards Airforce Base. I guess the pilot will have some good material to put in his book. It should be on the news tonight. Debbie

Chuck, I have a mirror cover and a scopecoat but one still needs to exercise caution. I recall at TSP several scopes were toppled over by the wind. Every year someone's scope is damaged at Texas Star Party because of the wind.

Star party etiquette for crumb crunchers and parents
by diveboss＠xmission.com 28 Sep '04

28 Sep '04

I volunteered to give a pre-star party etiquette briefing to a group of K-6 students and their parents, and was going over my notes regarding things that the little tykes and their parents need to know to help make an evening of star gazing more enjoyable for both the kids and adults. Outside of the obvious things like the meaning of "NO" and "STOP", I am at a loss and therefore appeal to the wisdom of the group for further insight as to what else I might say that will help make this event a success. Here is what I have so far: Watch where you're walking. Look with your eyes, not your hands. Don't touch anything. No running, yelling, shoving or fighting. Stay in line, be still and keep quiet. We'll be watching and if we see anyone with their fingers in their nose, they won't be allowed to look throught the telescopes. This should take care of the parents, now what should I tell the kids??? ;) Guy

Big copy scope lens
by Chuck Hards 26 Sep '04

26 Sep '04

http://www.surplusshed.com/pages/item/l3245.html I have mixed feelings about this lens; for about twice the money you could buy a real doublet corrected for infinity; on the other hand I've had good results with most copy lenses, albeit at low to medium magnifications. This might be a way for someone on a budget to get themselves into a 6" refractor relatively inexpensively. If anyone buys this lens, I'd sure like to take a look at it. (I already own a 5" doublet refractor, so I'm passing on it.) _______________________________ Do you Yahoo!? Declare Yourself - Register online to vote today! http://vote.yahoo.com

Head band lights

I seem to remember seeing folks at star parties wearing head bands with red LED lights that are used for chart reading in the dark. Anyone know where I could get such a head band? Thanks, Patrick :-)

Joe, There is a picture of the Green Flash in the latest Sky and Telescope issue. That picture looked a lot clearer than mine. We had morning and evening fog that day. Maybe I'll try from Santa Barbara next summer. It was clearer there than Ventura/Oxnard.
