Hi Folks;


I posted a shot of NGC 3828 (Fainter Northern member of the Leo Triplet) at:


http://tech.groups.yahoo.com/group/Astro_IIDC/files/DSO/NGC3828.jpg


The upper half is the LRGB image (20 minutes luma bin 1x1, 7 minutes red bin 2x2,  5 minute green, bin 2x2 and 3 minutes blue bin 2x2) and the lower half is the original Luma stacked image with no processing. 


That's the light pollution I have to deal with living on the southern  edge of Calgary. This is with a Hutech IDAS LPR filter which cuts the light pollution by 2.5 times.


I should have the new SSE3 optimized stacking alignment code out tomorrow for Astro IIDC 4.06.00 A2, which doubles the rate the stacking code runs at on x86. Performance with SSE3 is not nearly as good as what I can get with Alitvec. In fact a G4 1.25 gighaz Mac Laptop is slightly faster processing the same amount of data than a 1.66 gighz X86 Core Duo is. A G5 runs 2 times faster than both of them.


TTYL..
