I am trying to decide between the 80ED (OTA) or the Coronado
PST for X-mas:-) My only other scope is the Deep Space Hunter 10" (which should arrive tommorow or the next day). A small refractor would be nice. I'm thinking the PST might be better off as a third or fourth scope in the arsenal. What is the cheapest way to effectively mount the ED for casual observing? I am thinking of a strong alt az mount. The ED package looks OK, but the Sky View mount is only half of a full eq. mount, and I would want a Telrad for the finder anyways. P.S. Why are those TeleVue mounts so damned expensive?? -Tom |

I personally do not like alt-az for astro use with a telescope unless I am just using a real low power or using them with binoculars. But then, that is just me. Kruger |

Visit the Universal Astronomics web site at: www.universalastronomics.com There is also a Yahoo group dedicated to UA products.

....What is the cheapest way to effectively mount the ED for casual observing? Prior to piggy-backing it on my main scope, I successfully used my 80ED on a Slik camera tripod (cost about £70). It made a fantastic "quick look" system, particularly at low powers (20-50x). Higher mags are useable (I took mine to 200x for the moon a few times) but there's a lot of "nudging" needed to keep up with the sky at that power. Cheers Beats |

I have my 80-ED on an Orion AZ-3 ($140) -- an alt az mount with slow motion controls. I find slow motion vital when viewing planets and the moon at up to 200x (using a wide field EP). I have to dodge trees, etc depending on where the planets and moon are, so an EQ wouldn't be much use. I don't believe that the UA alt-az mounts have slow motion controls, neither do the Televue mounts You are correct re the UA and TV mounts. Some of us equate the 80ED and its brethren with lower power wider-field casual viewing not needing such controls. And some do use the UA mounts at 150x or so successfully. Phil |

I have to dodge trees, etc depending on where the planets and moon are, so an EQ wouldn't be much use. I don't believe that the UA alt-az mounts have slow motion controls, neither do the Televue mounts UA UniStar Light mounts don't need slow motion controls as they are exceptionally smooth, using teflon bearing surfaces in both altitude and azimuth. There is also a steering handle so that you can aim and track without touching the OTA. Highly recommended, although I'm not sure how "cheap" these might be considered. I use one with my ST102, and have used it with a C5 and a Starmax 127 OTA in the past. For hand tracking, as always, the issue isn't how much power you use, it's how large is the field of view at that power, which is more a function of the eyepiece at that point. For example, a barlowed 7mm Nagler Type 6 yields a half degree at 170x in a 600mm focal length telescope, that's why *I* use them ;-). Combined with the smoothness of the UniStar Light, there is little to complain about. Any vibration problems will be a result of the capabilities of the tripod, much of which can be taken care of with vibration supression pads, even using a lightweight tripod like the D&S CS Compact Short Tripod that Larry sells.

I am trying to decide between the 80ED (OTA) or the Coronado I am thinking of a strong alt az mount. Vixen do (or did) an altaz for this size of telescope. Complete with slow motions and a sturdy wooden tripod. "Cloudy Nights" has a review along with the Gibralter. Google will find them with vixen + custom Chris.B |

I use mine almost every (clear) day. |
