DSI Grey screen

Is it just me, of is the Meade DSI a pain to use?

I picked up one to use as a guide camera a while back and have now purchased a Stellarvue 60m finder to use as a guide scope.

The Stellarvue is great - light with good optics.

But the DSI is another thing altogether.

When plugged in, I get a gray screen with mush. After much fiddling about (including a few exposures), I can resolve some faint stars but I can't get the contrast right. Often there is so much static (wavy lines or just general electronic noise) that I can't make out anything on the screen. When I can, its a devil to focus.

The story is the same on the ED 80 and the LXD75.

As you'd expect, the manual ain't much use.

Have I picked up a dud, do I have unreasonable expectations or is it another case of pilot error?

Any pointers would be appreciated - especially a website that carries useful practical information.

Thanks

Pete

Hi Pete,

You will have to get used to the settings for the camera.
Your symptoms sound like you have the Gain turned up.
Try full Gamma, full brightness, but NO Gain. See if that helps.

I find it okay under PHD - for 2-3 second exposures it can grab reasonably faint stars.

Focus on something bright - say Jupiter on 1 second refreshes, and once that looks sharp - check its moons until they are at maximum sharpness.


Then set it to say 3 seconds and try of fainter stars.
