Digital compact camera - low light, low weight, and threaded lens

Has anyone had success in attaching a low weight, low light compact digital camera to a telescope eyepiece for imaging the night sky? I already have a good attachment using the following ETX-90 Standard Meade lenses Digi-T adapter -http://www.scopetronics.com/dtsystems.htm Olympus C4040Z camera Cam2com software -http://www.sabsik.com/ The problem is that the camera is slightly heavier than I would like. At 420 grammes it seems a bit of a load on the telescope. I'd rather avoid counterweights so I'm looking for a more modern and lighter camera. The basic requirement is that it have a threaded attachment like the one shown below so I can couple it directly to the eyepiece, and be low weight. One that has good low light performance would be good. The threading on which the Digi-T adapter mounts is just visible in this link showing the lens adapter tube that couples the Digi-T to the camera. https://emporium.olympus.com/innards...sku=200558-410 In case anyone hasn't tried it, the threaded mounting is far more solid and far easier to use than those awkward rods-and-rings bits of meccano that hold the camera via its tripod attachment. Asking on wider range of newsgroups. Maybe others have already gone down this road. Not sure if this will invoke derision from the CCD folks.... :-) -- James |

One thing you might try is to remove the batteries and use the external 120V power adapter. 4AAAs weigh 120 gm. Even if that leaves a heavy camera, it'll lighten the requirement for the counterweights, if you feel you still need those. |
