Default ASTRO: Holmes on the 18th UT

I processed the frames from the 18th many different ways, each shows
something different about the comet. One is shown on my scale image
showing its growth. I've attached two others. The first blows out the
pseudo nucleus but that helps me show a rather strong tail coming from
it and going through "The Blob" which is elongating from its original
nearly round shape. Several streamers exit "The Blob" (Where's Steve
McQueen?)

The other shows that there's a second blob just behind the pseudo
nucleus. It was lost in the stretch used for the other shots. It is a
very low contrast feature so I used a strong enhancement to bring it out.

This guy is very interesting to say the least.

All 3 images were made from the same 7 frames, only the curves used were
changed. The same RGB frame was used as well.

14" LX200R, f/10, L=4x1', RGB=1x1' all taken binned 3x3 as it is fading,
STL-11000XM, Paramount ME tracking the comet not the stars. Images
reproduced at 2" per pixel.

Third character is a zero rather than a capital "Oh".

Cool! I hope you get some more of these "detail" shots showing what's going
on in the inner coma. All I got here is endless snow and rain and that's the
forecast for another week or so.
