We'll do another one when you are available. We can never have to many star parties.

RE: [Utah-astronomy] Re: Planetarium at the Univ of NV, Reno

Thanks Chuck. I mostly agree with you - however, sometimes old buildings just can't serve "modern" needs. I'm not familiar with the planetarium, but it sounds like you are right in this case, "needs" simply means fluff/fru-fru/BS - whatever you want to call it, not science. I like the idea of a new science center in the old building. I hope they can pull it off, especially if it means saving the planetarium theater and continuing its use. I hope the building's preservation doesn't just mean bastardizing it for an inappropriate use. I lived in Long Beach CA when I was seven years old. I have fond memories of the Griffith Planetarium where my parents frequently took my brother, sister and me for a weekend jaunt. It was sad the last time I was there to see that so many of the old science exhibits had been replaced with trinkets. I wasn't able to stay for a star show - I hope those hadn't gone the way of everything else.

Filter seminar
by Chuck Hards 23 Jan '03

23 Jan '03

You guys better go-ahead without me. I just realized that Jupiter and Saturn will be just about history by the time I can spend any time at the eyepiece (other than the back yard during stolen moments), and if Mars has a dust-storm, you can kiss surface detail goodbye...do it now, while Jupiter and Saturn are at their best. Also, for those with large scopes, try and detect the chevron pattern in the clouds of Venus, using violet and bluish filters. Let me know if any conclusions are drawn. Sigh.

RE: [Utah-astronomy] Brent's view
by Kim Hyatt 23 Jan '03

23 Jan '03

Interesting topic. I have an old color filter card - I don't remember who used to make them. There are about eight different colors of "gels" and the optical quality seems OK. I believe that the gross detail has been easier for me to spot on occasion, but my experience with the fine detail has been like Brent's - the filters seem to degrade things. However, I would like to experiment more. -----Original Message----- From: Brent Watson [mailto:brentjwatson@yahoo.com] Sent: Tuesday, January 21, 2003 1:34 PM To: utah-astronomy(a)mailman.xmission.com Subject: Re: [Utah-astronomy] Brent's view My issue with filters is not the color change. My issue is that they degrade the image. When I look at the planets, I am trying to see as much detail as possible. My experience is that the filters do not allow me to do this. I know others see an improvement, but I do not. In fact, the image contains less detail. What is there after the filter does its dirty work may or may not be more apparent. Your mileage can, and does, vary. (I wear brown tinted glasses when I wear dark glasses. They cut the blue light more than the red, and hence do not deplete the rhodopsin as much.

Tuesday's SLAS meeting
by Ben Record 23 Jan '03

23 Jan '03

Sorry, I don't know any information about these meetings, and I'd really enjoy to go to one if possible. Is there any way someone could inform me on what time, and place the meetings are at, I'd really appreciate it. Many thanks, Ben _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963

Apology

My last message was to have only gone to Dave. My apologies for discussing a personal matter on the list. This is one of those times when I wish there was an "unsend" button. Patrick

Shuttle reentry update
by Patrick Wiggins 22 Jan '03

22 Jan '03

Here's the latest from JSC: "I've heard that the STS-107 orbit altitude is actually a little higher than planned, which will probably shift the entry groundtrack farther south and later in time. I won't get the revised entry data until Jan 27 or 28, so right now I don't know how much it will change. I'll send you the updated predictions when I have them." Patrick
