Interesting stuff!  I can't wait to hear your specifics!

Hi Chris;

I can't talk about specifics yet. I will after I am done with the  

Camera and they have addressed the issues I have found.

The camera seems to be quite something... looking forward to more  

details. How is the spectral sensitivity?

Multi core support is highly welcome since all the new hardware  

offers plenty of CPU cores to use.  ;-)

regards

Chris

Hi Folks;

Little status update...

I am testing a new Monochrome low noise Camera and adding support  

for it to Astro IIDC 4.08.00 (still in progress). I'm under NDA on  

the camera, so you'll have to wait before I can talk about it :) I  

plan on writing a review up for it - but needless to say the flat  

frames I have taken with it uncooled are amazingly uniform and  

exceedingly low noise - even uncooled.

In any case, here is my first Astro Light with the camera of M42  

Core, taken at 1625 mm focal length with AT8RC scope and 30 second  

Luma, 30 second Red, 30 seconds Green and 35 seconds Blue. Uncooled  

Camera temp was + 7°C internally and ambient temp was -2°C, so it  

does not warm up much. I shot no Flats or darks, so this is  

basically raw out of the camera. Seeing was bad and even guiding at  

15 fps on a mag 3 star, I was getting stars jumping +/- 5 arc  

seconds between guide frames. I under exposed it to preserve the  

core and then log sqrt stretched it in Astro IIDC to bring out the  

Crab "arms":

Here is the original Luma stacks from the Camera without any  

processing:

Lastly, I am in the process of re-writing the stacking code to use  

all available CPU cores. After a couple weeks of work, I finally  

solved the last of my bugs (threads going rip van winkle) this  

afternoon and it looks like this should significantly speed up  

stacking over the old method - especially if your on a 4 core or  

higher Mac. Even on a 2 core Mac, I'm getting around a 30%  

improvement now than the old code, but if your running multiple  

(maximum 16), core, all of them run in parallel and it screams.

Clear Skies..
