Anyone up for the gravel quarry Saturday night?

I'm hoping to get enough of my honey-do list done Saturday to get away guilt-free while the weather's good and get some Fall observing in. Anyone else that wants to join me just East of Park City?

Dave, Congratulations!! It was a beautiful shot, well composed, and worth publishing. I'm glad someone finally recognized that fact... (By the way you have now exceeded your 15 minutes by approximately 250%. A bill will follow.)

Re: Orion 80mm ED APO

I got the shipping notice on this today, so the backorder delay wasn't nearly as bad it initially appeared. With luck it will arrive while the high pressure is still stuck over us. I also tried Orions "mag-wheel" focuser knobs, installing them on a 1.25" focuser, as well as a 2" focuser. Looks aside, they improved the feel and function of both, due mainly to their increased diameter over the stock knobs. Just a little more leverage makes a difference. The rubber grip ring is a nice touch. The 80mm scope appears to have similar knobs, judging from the photo, although it is supposed to be a Crayford-style rather than R&P.

RE: [Utah-astronomy] Fwd: Rigel and companion
by Kim Hyatt 15 Oct '03

I've never had difficulty with Rigel with an "unmasked" 10-inch f5 Newt. If I can't make out the companion, I wait an hour for the position to change and to see if it was lost in the glare of one of the diffraction spikes from the secondary, or I try rotating the tube assembly. Even with bright diffraction spikes, Rigel's companion hasn't been difficult for me. Not so for other pairs I've tried observing that way. I believe that the same principle behind the "apodizing" mask makes observing close doubles easier with a SCT than with a quality refractor of comparable aperture. This was apparent one night in May 2001 while observing Eta Cor Bor with both Don Colton's Ultima 2000 (Celestron 8-inch SCT) and Siegfried's 9-inch Clark. The large central obstruction of the SCT in effect made the Airy disk proportionately smaller than that in the Clark and allowed the pair (0.8 arcsec, as I recall) to be split easily. At the same time, I couldn't split the pair in the Clark, nor I believe could anyone else. (I was so impressed by the performance of the Ultama 2000 that two weeks later I bought one myself. Siegfried wouldn't part with the Clark for the same price, although I offered...) -----Original Message----- From: UTAHDEB(a)aol.com [mailto:UTAHDEB@aol.com] Sent: Monday, October 13, 2003 1:14 PM To: utah-astronomy(a)mailman.xmission.com Subject: Re: [Utah-astronomy] Fwd: Rigel and companion Joe, According to the Astro-League's Double Star list, the separation is 9.5 arc seconds and the PA is 202 degrees.

I'll try to take a picture of Rigel this winter with my digital camera. I don't know if more vanes could help.

Thanks Deb, I'll take a look. -----Original Message----- From: UTAHDEB(a)aol.com [mailto:UTAHDEB@aol.com] Sent: Monday, October 13, 2003 1:55 PM To: utah-astronomy(a)mailman.xmission.com Subject: Re: [Utah-astronomy] Fwd: Rigel and companion Wow.
