Shot these at F28 Seeing was sub-1 arc-sec occasionally.  Really was great viewing.  Zooming in to 66% resolution on the big screen was engulfing in the living room.  

 

A little discussion on B/W vs. Color.  Thought I would throw these two out there.  The only difference is Level adjustment was changed to R=1.8 G=0.6 B=0.8 on the raw. 

 

I used to interpret thermal images, always preferred using black/hot or white/hot, all other palettes were not as valuable. 

 

Can't really say much here.  My wife thinks the "Color" image is by far the best show.  To me the B/W shows more science and sometimes the science is paramount.

ps. still have 1.6Tb to process,LOL!  Sure glad I am Retired Now!  (3 days and counting...)

I’m one for color.

Sure B&W shows detail different but as I’m just visual color is what I’m used to pulling detail from .

Congratulations on retirement, that’s when I changed my email signature to “Everyday is a Friday” and I’ve enjoyed them all since 2007.

Well, I haven’t taken that into consideration before!  I guess I tend towards B&W more because I cannot duplicate the visual color and view that my eye sees through my Lunt.  Our eyes can detect such a dynamic range that I have never seen a color image of an Ha view that can really show what a flare looks like visually or the crispness that proms have along with disk details.  So in my mind, the B&W comes closer to the detail view my brain registers rather than an image that is any other shade than red.

I used to work on OH-58D Kiowa electronics systems including the Multi Function Display, it was green.  I was told that is because the human eyeball is most sensitive to green so I asked Copilot the Bing AI and the answer was:

 

The human eye is most sensitive to yellowish-green color in daylight1. This sensitivity is due to a combination of factors related to our evolutionary history and the biology of our eyes. Specifically, green light at around 555 nanometers stimulates two of the three types of cones (L and M) almost equally, making it the color to which our eyes are most responsive2. So, next time you’re out enjoying the great outdoors, remember that your eyes are particularly attuned to that lovely yellowish-green hue!

 

So with that in mind maybe we should choose the 555 nanometer wavelength spectrum for scrutinizing our solar images.  I will see if I can give it a whirl.

That's why the Continuum filters are in that ballpark at 540nm ... wink.gif
