So.. New subject..
How do *you* connect up
cameras so the scope can access everything it normally can access (in the sky)..
?? My CMOS cameras both have short USB cables, which I plug into the computer
that sits on a table right next to the scope to the East of the mount.. For
Planetary imaging, for instance, this means I can only image from slightly
before the Meridian
to the Western Horizon.. I can¡¯t image, say, 45 degrees up in the East.. When
I move and get back into Astronomy, I hope to be able to operate ¨C i.e.
place the table ¨C to the north of the mount, and I assume that will give
me some access to both sides of the mount, such as from 45 degrees up in the
East to 45 degrees up in the West..
??? BUT! What
does it take to get farther from the mount, say ten feet?? I have a multi port
USB hub, so do I just plug both cameras into that and then run a new USB cable
from the hub to the laptop?? And do I mount the hub to the tripod??
?
??? I ask,
because I have previously tried to run the camera with a 6¡¯ cable instead
of the 3¡¯ cable it came with and it dropped almost all the frames, so I
am *ASSUMING* USB has severe cable length issues???
Some
Notes.. The 6¡¯ cable was ¡°good¡±, as at the time I had two ASI
cameras and both camera cables came with them.. the ASI178 came with the 3¡¯
and the ASI120 came with the 6¡¯.. Since I wasn¡¯t guiding at the
time, I could use either cable.. Also, these *ARE* USB3 cameras and my laptop
only has USB2 ports.. This hasn¡¯t been a problem yet.. I have imaged at
200 fps, albeit not full frame, and I don¡¯t see that transmission rates
over the USB cable would be an issue when only sending an image downline no
faster than every 60 seconds..
??? So how
would I ¡°move away from the mount¡±?? What are my options?? Please
speak slowly, as ¡°USB Hub¡± is the only phrase I know in this ¡°foreign
language.. :-))
