[edwin hubble <hubble_edwin@xxxxxxxxx>]

With reference to Chris Schurs's technical specifications for his Comet
Tuttle 8P image of December 30:

"... Camera:  Hutech Modified Canon XTi @ ISO800
Exposure:  45 x 2m Continuous dual stream ..."

and Dean Ketelsen's question January 1:

"... I assume when you say "two data streams ... were brought
together" that you mean that you removed the comet from each frame and
co-added and realigned it to the co-added shot of the galaxy? ..."

--------------------------------------------

Does "dual stream" refer to an operating mode where the camera produces
simultaneously files in 2 different formats ??

For example, a video camera specification might say:

" ... 30 frames per second on dual stream mode of MJPEG and MPEG 4 data
..."

I am also interested in how the two streams were brought together,
thank you.
