>From SLC head north on I-15. Get off at exit 335 and head west. You are on Antelope Drive. When you get to the other side of the causeway go left. You will see a sign for White rock bay trailhead and park headquarters. Turn left (the only way you can go) and then turn right onto the dirt road. When you get near the bottom of the road dirt road goes of to the left. Turn onto it and it will take you to the parking lot for Whiterock Bay Trailhead. I expect to get out there by 6pm so I should be there with my White Expedition. -----Original Message----- From: Joe Bauman [mailto:bau@desnews.com] Sent: Friday, August 16, 2002 7:04 AM To: utah-astronomy(a)mailman.xmission.com Subject: Re: [Utah-astronomy] Perseid colors Dave, can you send us directions on where?

Dale Hooper tracked it down for us out at the Antelope Island Star Party. We didn't get any pictures either. We watched it for several hours. The color and size looked a lot like Neptune. The motion was like a slow satellite.

Was having too much fun just watching it and showing it to others. It really was neat to actually SEE it moving. I've never seen an asteroid move before. However, during a close pass of another asteroid last year I took bunches of images on three consecutive nights and had them spliced together into a "movie" that shows how the apparent motion increases as distance decreases. See it at the bottom of http://planet.state.ut.us/slas/patrickw/patrickw02.html . Cheers!

2002 NY40 seen from SPOC

Very nice view for a dozen or so of us of 2002 NY40 tonight using the Ealing at SPOC. First time I've ever detected movement in an asteroid. Fun show. Patrick

I'm not sure what focuser you received with the paramount, but, with some focusers the autofocus routines in CCD Soft or Maxim DL can be used (i.e. robofocus or Optec TCF). In addition, there is some freeware software called FocusMax that will work for the above focusers and will soon support the Meade electronic focuser. I believe it can be customized (it's ASCOM compliant) so it may be able to work for you. There is also a knife edge focusing aid from Stellar Technologies called the Stilleto IV that could help you if you can't use the autofocus software. There is also the route of making one of your eyepieces parfocal with your particular CCD camera. I hope this helps.

Perseid colors
by David Dunn 16 Aug '02

16 Aug '02

I think it was Joe that was asking about his purple meteor last week. In APOD today they have a rainbow colored perseid. They claim that the eye doesn't pick the colors up very well and that film will show the colors. Also, a reminder that the Powder Mountain star party will be held at Antelope Island on Saturday night. Everyone is welcome to come out. People bringing telescopes to help with the star party are admitted to the island for free. See you there. Dave

RE: [Utah-astronomy] CCD focusing

I don't have any experience with it, but I do know after shopping for a new focuser that Jim's Mobile (JMI) sells digital read-outs that can be installed on a focuser. This presumably allows you to set/keep the focuser to a setting accuracy down to 0.01mm. Here's the URL: http://www.jimsmobile.com/dro_data.htm It's too bad CCD cameras don't auto-compensate for inaccuracies like an eye can. In fact, this actually brings up a question. Does anyone have any tips for visually achieving true focus. I find I sometimes have difficulty with this when I am trying to get the scope in focus at a star party for people to view an object. Usually I can look away from the eyepiece briefly & look back but sometimes my eye compensates too quickly. This is even worse after swapping to a higher power on a nebula where the surrounding stars are either too dim or practically non-existent with a filter. A nebula isn't exactly the easiest thing to focus on... I wonder if this is a more of an issue for those of us who wear eyeglasses. ---------- From: Patrick Wiggins Sent: Friday, August 16, 2002 12:14 AM To: utah astronomy listserve Subject: [Utah-astronomy] CCD focusing Anyone here have any experience with CCD focusing aids? For those who have not tried CCD imaging, getting a precise focus is not easy...

Asteroid 2002 NY40
by Dale Hooper 15 Aug '02

15 Aug '02

Hi All, Just in case you haven't already heard, asteroid 2002 NY40 is going to provide a rare treat Saturday night to Sunday morning. On its closest approach it will be traveling with an angular velocity of 8 arc minutes per minute!!! Here is a URL with more info: http://skyandtelescope.com/observing/objects/asteroids/article_697_1.asp I'll definitely be watching it from Antelope Island with the rest of the OAS. I think I'll try to track it with my STV. Thanks, Dale.

RE: [Utah-astronomy] Perseids

I observed from about 10 miles south of Evanston, Wyoming along Hwy 150. Skies were dark with a few clouds to the north and west. I noted quite a few very bright meteors between 11:45 pm and 12:15 am, mostly to the south. Many left a long, whitish-orange trail which persisted for a maybe 5 seconds. During this 30 minute period, I seen about 40 meteors. The numbers dropped significantly between 12:15 and 12:45 when I called it a night due to clouds and having to get up early. -----Original Message----- From: Joe Bauman [mailto:bau@desnews.com] Sent: Tuesday, August 13, 2002 9:58 AM To: utah-astronomy(a)mailman.xmission.com Subject: Re: [Utah-astronomy] Perseids PS: Dear friends, Anyone interested, please send me a note quickly.
