New to the Forum - SV605CC - USB Question

[Jupiter 2]

I have been working at Astrophotography for about a year now. Mostly on my own. I started with a SV105, upgraded to SV305C, and now SV605CC ( got it at a good price last week). My user name (Jupiter 2 - From TV - Lost in Space) is appropriate because I am lost most of the time.

I attached the SV605CC to my SV503 80MM yesterday. I downloaded drivers twice. Opened Sharp Cap. Everything seem to work fine at this point except the USB rating will only go as high as 2 for a USB3 connection. I am using a new Acer Aspire Laptop which has 2 USB 3 connections. I tried both and still Sharp Cap does not see anything but a USB 2. Ordered a new USB 3 cable on the off chance that is the problem.

What have I done wrong?

Thanks

Hi Gary,

I think this is simply a misunderstanding... The 'USB' setting in the controls on the right is just a number that indicates how fast the camera tries run the USB data transfer - it has nothing to do with USB 2 or USB 3 connections.

Setting that number to the maximum possible will (potentially) get the highest possible frame rates out of the camera, but the camera will also be more prone to glitches/instability/lost frames. If you are doing planetary or lunar/solar imaging then setting the highest USB speed option is probably best - if something starts to go wrong then you are there to correct/adjust if necessary. On the other hand for deep sky imaging, high frame rates aren't important at all, so you might set the USB speed to minimum to take advantage of any additional stability that it brings.

Hope this helps,

Robin

If you ever want to investigate USB connections, download USBtreeview https://www.uwe-sieber.de/usbtreeview_e.html

If the device shows S, this indicates a Superspeed (USB3) connection.
If the device shows H, this indicates a Highspeed connection (USB2).
