Default ASTRO: IMPORTANT UPDATE ON COMET

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/com...tokes_page.htm

in particular scroll down the page and look at the image that differences
the output of the 90 and 0 degree analyzers:

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)

What's the 'RG Processing' ? I haven't heard of that before. Some kind
of wavelet transform ?

interesting structure! but what does it mean? what can we learn from these
false colour images?

solid cloudcover for days here.....

Sure Guy would publish them in a circular

Very interesting results, Richard, particularly the image with 90 degree
rotation. In it, I see three central points that make a kind of triangular
arrangement with what appear to be jets emanating from them. Are those
locations of jetting out of the core, or has this object actually
fragmented, and we are seeing three cores in that image? I don't
understand the method you are using and what it is supposed to show, which
is why I ask these questions. I hope they don't appear to be stupid ones.
At any rate, Great work. I assume you are going to publish your results.

George

Amazing images Richard. This technique really brings out detail that is not
visible in "normal" shots.
Have you tried something like a Larson-Sekanina filter on your "white light"
images? Would be interesting to see if it is possible to get similar detail
that way.

Stefan,

Here's L-S processed of my white light image. Rotation is +/- 5 degrees.
Much better than what I had before.

Eric.

Looks like a spider :-) I'm just playing with my own images as it has
cleared up over here...
