With inspiration from nytecam, I took a crack at the latest comet in the skies.  Took some real-time IIE videos, IIE stills & natural light stills below on the evening of Aug 23/24 2014 from Mount Pinos Calif.

Very nice! thanks for posting these. My favorite is the Mewlon 250, 30 sec, 16,000 ISO, A7S image. Also the first one seems to show a direction for the tail.

Chris, A high tech image intensifier. Basically it's a very sensitive real time night vision setup.

Wonderful stuff. Out of curiosity what do you think the comet would have looked like in an A7S video?

Another awesome comet capture! 

 

Where's C/2013 V5, kinda bummed you didn't post up anything on this one, seemed to have a bit more wow to its structure?

 

I'll be posting some image intensified captures once I sift through all the clips, been capturing these two for the last week so there a bit of data to go through.

Another comet?!  You're messing with my Labor Day weekend, cnoct.  I might give that one a try.  Anxious to see your vids.

Thanks.  I seem to recall that it was VERY faint.  At max A7S ISO and slowest frame rate, I think I had enough of a fuzzy blob to help frame the target and that was about it.

The Star-Tron stuff is something else, perfectly matched to image intensifiers, wish the contractor that produced the lenses was known but probably wouldn't matter as far as having them make up a run of them.

 

You've taken image intensified astronomy to an epic level, awesome stuff!
