3600 GTO
snightingale40 <snightingale40@...>
Well, as I was staring at the new mount on the AP website my wife came
in and was convinced I was looking at porn. I'm on the list, there MUST be something I can sell around here...... Seriously Marj and Roland, I hope you are taking great pride in creating this wonderful piece of equipment. Congratulations. Steve

aligned particles of the right size relative to the wavelength of light will polarize light

you can get the same effect off the surface of a lake too the flow can align the particles: both solar wind for the comet as a whole and the mass outflow from a jet: both can have the effect of aligning elongated particles more or less in the same orientation here's a bit of info from a friend: thanks to Dr. Liebrecht Venter for bringing this to my attention, I'd say that the polarization difference imaging method I used to photograph 17/P Holmes apparently is a useful diagnostic technique to probe the comet's composition http://www.springerlink.com/content/p25k608154667745/ Polarization of Light Scattered by Cometary Dust Particles: Observations and Tentative Interpretations Journal Space Science Reviews Publisher Springer Netherlands ISSN 0038-6308 (Print) 1572-9672 (Online) Issue Volume 90, Numbers 1-2 / October, 1999 DOI 10.1023/A:1005250131509 Pages 163-168 Subject Collection Physics and Astronomy SpringerLink Date Monday, October 25, 2004 A.-Chantal Levasseur-Regourd Abstract Analysis of the polarization of light scattered by cometary particles reveals similarities amongst the phase curves, together with some clear differences: i) comets with a strong silicate emission feature present a high maximum in polarization, ii) the polarization is always slightly lower than the average in inner comae and stronger in jet-like structures. These results are in excellent agreement with the Greenberg model of dust particles built up of fluffy aggregates of much smaller grains. Also, they suggest the existence of different regions of formation, and of different stages of evolution for the scattering particles inside a given cometary coma.

Re: 3600GTO - El Capitan unveiled at AIC

Marj,
Any possibility of a package deal ... AP3600 + pier + counterweights? I realize the last bit (counterweights) is a bit of an unknown since most people will have differing needs but, given the capacity of the mount, I think we can all guestimate the amount of counterweightage needed. This looks like one sweet mount ... and so is the pricing!!!!
