Guiding, QHY5 or DSI 1c

I currently guide using a QHY5 and an ED80 scope however sometimes I fail to find a suitable guide star and have poor signal noises (CMOS Chip)

Would I be better changing to use a DSI 1C (CCD Chip) as there's one going cheap on Astrobuy/sell? (Or a DSI 2)

Which would be more sensitive?

Comments/advice please

I think it might be due to guiding from within Maxim. With PHD I had less problems; I'll go back and re-try PHD.

In trying to convert to Using Maxim as a think it has a slight edge with accuracy and can be controlled in a remote obs setup.

In maxim I currently use 5 sec subs!.

This was triggered as there are a couple of DSI 1c and a DSI pro going cheap at the moment

cheers

Rob
