Using the Sentinel Telescope out by Duna

[xerogravity]

 

I have a Sentinel equipped satellite in a solar orbit just inside the Duna orbit. Plenty of power etc but after a lot of observing all I've seen is one massive asteroid. Most of the time there is nothing. I had hoped to find a medium sized asteroid to capture and bring into Duna orbit as the basis of a refuelling station (through ISRU). So far I've found 1 massive object way too far from Duna to even think about grabbing. I was hoping for a selection more like what is around Kerbin (both in numbers, size variation and range).

Is this is as good as it gets in the game or can I somehow coax the Sentinel to be more productive? I've even tried pointing the telescope lens directly at Duna! ;-)

Isn't the sentinel supposed to look away from the sun? If you put yours in an orit above Duna, it will be lookin inwards instead. That may be why it finds next to nothing.

Put your telescope in an orbit in between Kerbin and Duna. That should allow it to find asteroids around Duna's orbit.

Thanks for the reply but that is how it is set up at the moment; "in solar orbit just inside the Duna orbit"

Would it be better to have it well inside the Duna orbit? My thinking was that I want asteroids close to Duna, not on the far side of the orbit so I didn't want the telescope to start racing away from Duna by being too far inside the Duna/Kerbol orbit.

Perhaps the telescope is set up to function in such a way that, wherever it is relative to Duna, so long as it's between Kerbin and Duna on a solar orbit, it only finds asteroids close(ish) to Duna? If so, I'll move it into a solar orbit half way between Kerbin and Duna.
