Since you haven't gotten delivery of your AP1200 yet, I hope you haven't poured the concrete for your 1200 pier. You're going to need a bit more for the heftier 3600 pier. Just in case you forgot about that ... Joe

Thank you to the great folks at AP - the 3600 is great news!!
I am about to receive my new 1200 in a week or so, and now I am already on the list for the 3600... :-) I am so happy I will be receiving the 1200, but hey, it will have a very short tenure in my observatory, and then it will be my "portable" mount when the 3600 arrives! Considering everything I am mounting on the 1200 I will be happy for the capacity of the 3600!! I am so eager, the photo of the 3600, with its little brother - the 1200 - is now my computer wallpaper!!

IMPORTANT UPDATE ON COMET
Richard Crisp
I discovered a flaw in my processing flow for the Polarization Difference Image of the Comet 17 / P Holmes
I have since corrected and have extraordinary results to share. *I am serious, you must have another look*. http://www.narrowbandimaging.com/comet_17_p_holmes_stokes_page.htm in particular scroll down the page and look at the image that differences the output of the 90 and 0 degree analyzers: direct link: http://www.narrowbandimaging.com/images/comet_17_p_holmes_90-0_crisp.jpg the structure revealed using this technique is truly remarkable. I wish I had more than 3366mm focal length available with clear skies right now (and good seeing too)

aligned particles of the right size relative to the wavelength of light will polarize light
toggle quoted messageShow quoted text
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.

I see you must have been a fan of the "6 Million Dollar Man" TV series where he cost 6 Megabucks, but his dog Maxamillion ... only a megabuck. But, I see that you can be right - it will be interesting. I just hope you aren't putting prices in Roland's head, prematurely, or it will be a self fulfilling prophecy :-) Joe

The advantage over a fork is more compact size and lower vibration for an given weight. When I get back next week I will post an image of this concept.
