Two more NEOWISE stacks from last night, with more detail showing

[michael.h.f.wilkinson]

I re-stacked the data with the 50-100 mm zoom with flats, bias and darks, and got a clearly better result, I feel

I also stacked just 10 of the long sequence of images I took with the 200 mm F/2.8 (30s, F/2.8, ISO 200)

Quite a bit of detail coming out. These were stacked in Astro Pixel Processor, with some tweaks with GIMP. Both show signs the ion tail has two different colours showing: blueish on the right and orange on the right.

I don't think I can stack more images in APP without incurring motion blur of the comet, so will give DSS a spin. That may take a while, because of the need of manually labelling the comet location in a HUGE number of files.

Thats stunning!

[Pete Presland]

WOW, that is some image!  The detail is tails is quite superb!

[Graham Darke]

Awesome Michael! 

[Victor Boesen]

Amazing photos! I tried the comet mode on about 180 images (yes pain in the ass) spanning an hour and it didn't really work out great. Perhaps I'll try again...

ABSOLUTELY   FAB  U  LOUS !

Wow and double wow. I like both pictures.

You might find it quite quick as your data is probably clean so the comet centre is easily marked and saved.

Lovely detail above

As far as I'm aware, you only have to mark the comets position in the first and last frames and DSS will automatically sort out the position of it in all the other intermediate frames.

Stunning result Michael, so how did you stack it in the end (read your problems with DSS comet mode post)?

Remarkably good. I wish I knew more about image processing. I'm just a photographer and that's what I get, photos!

These are simply short enough stacks that avoid visible comet motion.

That's what I did with mine for this comet.  

Stunning gas tail as well as the dust tail, well done.

Still want to see what I get if I stack all 15 minutes' worth of data in the 200 mm case

[DarkAntimatter]

Wow!  That looks like it belongs on the cover of an astronomy book.  

[Moonshane]

Blimey Michael. That's incredible.

I am also having problems stacking the comet, tomorrow I will try the much older DSS version I have on the XP disc.
