Hi James,

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 ...

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!!

Hi Marge,
Does the price include lumbar disk/hernia repair surgery? :)

You are going to be sadly disappointed.

Meade sells their big mount for that $30K, surely an AP mount must be
worth, I would guess, 2-3 times that much.

The Takahashi EM-2500 Temma-2 Mount with a 155 lb. load capacity is $46K.

If you base it solely on the relationship between the mount number
and the price of a fully equipped mount (counterweights, dovetail,
etc)... AP900 is about 9K, AP1200 about 12K, then the price would be
about 36K for the 3600 mount... I'm betting more.

Let's get up a pool and maybe Roland will give a free one as a prize
to the one who guesses correctly!


Jerry,

It's entirely likely that the AP3600 is/was meant to provide those AP
Customers a mount that is equal to or surpasses the Bisque mount. And
from the looks of they have indeed done exactly that. So in that light
$15K would be about right.

The Meade mount at any price is still a Meade :( Besides ..... didn't
that price include the optical tube ?

Marj: Put me on the list. I'll take one <g>

Regards

Bill

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)

Looks like it will come in between $19-20K, depending on the final
configuration and number of mounts we produce in a run (the more mounts, the
better the break on the material and the setup costs are spread out).

Re: OT: Comet 17 / P Holmes: Stokes Parameter polariztion difference image and Halpha

Richard Crisp
 

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

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.

Good guess Jerry,

Hi from AIC:

Believe it or not, this new mount can be configured with an
astrographic pier to allow all-sky coverage with no meridian swap. 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. The first prototype that is being installed in Antarctica has
such a configuration that allows tracking 24 hours per day.
