We are a leading telescope dealer and know the devices we sell.It not only matters which telescope you buy but also where you buy it. 8' aperture reflector optics reveal detailed views of the planets and Moon, as well as deep-sky objects such as nebulas, galaxies, and sparkling star clusters. OTA with 203mm aperture and 1200mm focal length Innovative GoTo Dobsonian reflector telescope with fully motorized object location and automatic tracking of over 42,000 celestial wonders.Included in delivery of Dobsonian Orion N 203/1200 : The entire construction distinguishes itself by its insensitivity to wind and its stability. The components of the telescope are both easy to handle and light the telescope is eminently portable and can be assembled in just a few steps and without specialist knowledge or tools. The tube holds position as it is suspended in perfect balance. Orion 8945 SkyQuest XT8 Classic Dobsonian Review. The Dobsonian base turns on smoothly running Teflon bearings, so allowing jerk-free, effortless movement of the telescope. Focusing on models up to 150mm aperture is via a 1.25" rack-and-pinion drive, and from 203mm aperture a 2" Crayford focuser is used. The soda lime glass mirror is supplied with high-quality aluminium and silicon dioxide coatings. Maybe the guys at the telescope store (astronomics, orion, or whoever) will have advice.The optics of this Newtonian reflector telescope are of Orion's customary high quality. I think it is worth a try, but it might not work (maybe you can't reach focus, or the thing will be impossible to balance, and there may be other unanticipated difficulties). will there be a balance issue with a heavy DSLR on a little xt8?Īs to the question "is it worth it?", that depends on how much your friend wants to take pictures. It is likely that mount jiggle will be the limiting factor for shutter speed, not moving sky. Probably could have gotten away with longer, but I don't know exactly. I've take pictures of the moon with a 12 1/2" f/5 dob and 2x barlow, which is almost three times the focal length of the XT8. I think the only possibilities are the moon, Jupiter, and Saturn. Will we be able to take shots of any in-between subjects, like say Jupiter or Saturn? And what sort of exposures will we be limited to? 1/50sec? Faster? On the other hand, close-ups of the moon should work out fine. So, the question is: is it worth it? I'm sure that, even at ISO 1600, most faint stars will not be visible. In this case, the t adapter has been inserted into a 2" extension tube.). Here is a picture (works the same for a dob. ![]() Obviously, no long exposures will be possible unless your friend has some kind of equatorial platform for his telescope. Cuenta con un espejo primario parablico de precisin de 8 pulgadas (7.992 in) marcado en el centro de la fbrica para una colimacin precisa y montado en una celda de soporte de aluminio fundido que proporciona la mxima ventilacin. Some people cut their truss tubes but I don't think one would do that to an xt8. El telescopio Dobsonian clsico Orion SkyQuest XT8 combina una ptica potente con lo ltimo en simplicidad mecnica y estabilidad. The primary mirrors of some dobs have a lot of travel (via collimation screws) but not all do. You can fix the out travel problem with an extension tube, but there isn't always an easy fix for insufficient in-travel. You can get them at You may want to call to check my facts and make sure the thing you get will work with the xt8 (some scopes have quirks).ĭobs (eg the xt8) don't always have enough in-travel to reach focus when you attach a camera. The t-ring connects to the t-adapter (I think that's how it works. The t-ring fits to the camera, the t-adapter fits into the 2" focuser of the telescope. Your friend needs a t-ring and a t-adapter.
