What, exactly, does Semi-APO mean? If it does not contain a low dispersion glass in its two element objective how can it qualitfy as an APO, semi or...
Hello Folks, I have the SVP100mm refractor f/6. I also own the Baader FringeKiller and Skyglow filters together with some very good results for eliminating CA...
When anybody gets one of these I'd like to hear their impressions about the optical quality and build of this OTA. It looks like it may be a hot sellor. The...
Tom; If you are sure that you have good optics then you could theoretically go to at lease 50 power per inch of aperture under very good viewing conditions....
Jim; Semi-Apo generally means a refractor that uses special glasses, normally ED, to reduce color error to substantially less than a standard flint and crown...
... It is most likely a rebadged William Optics ZenithStar, the Megrez is a little differnt, and is an ED APO. Interesting to see what the response to this...
Hi Rich, Thanks for the response. I guess where I have a problem with semi- APO is when, as in this case, there is no mention of special glass material or...
The recent addition of a Williams Optics 80mm short tube does rather prompt the question; why does Orion re-badge products with their name? What is the point?...
Hi Jim, I, like you, buy most of my astronomical equipment from Orion because of the convenience, high quality, customer service, fair prices, product...
To my Orion group freinds, I have been asked about the Idaho Star Party from members of other groups that I am a part of, and I thought that maybe someone here...
... groups that I am a part of, and I thought that maybe someone here just might want to know about it too. If you are not interested then don't read on. ...
Hi Mike, You did make me Laugh Out Loud! That is too funny! I hope that you and your black water heater have a good time with Deep Impact tonight! Happy 4th...
Hi, Well the view from the Boise site at Blacks Creek was not so good. We were fighting wispy clouds in that area of the sky for most of the evening. A lot...
... We were fighting wispy clouds in that area of the sky for most of the evening. A lot of us showed up and we had some very large scopes but no one got a...
At least you guys saw the comet, I tried last night and Temple-1 was just too faint for the pervasive haze and light pollution to even show up. I had a...
Atleast YOU as well had clear skies, here in BC nothing but thick clouds (well thick clouds for the last few weeks!) ... just too faint for the pervasive haze...
thinking about buying my first telescope. how does orion rate compared to other brands. was thinking about a space probe or deep impact. whats the difference...
Hi Whirlibird, I have had my first scope, Orion Observer 70mm EQ refractor, for a couple years now. Even though it is a small scope, it consistantly out...
Howdy there, I am wondering if anyone here installed a telrad to a starmax. I mean i know its easy but has anyone done it without actualy sticking the base to...
hi wirlibrd, I owned the 130st . ( short tube ) ,that one has a good parabolic mirror and comes with plossl eypieces , a step up from the standard 130. Both...
The longer tube (the scope with the slowest f/ratio) will give you better planetarie views while the shorter telescope (the fastest f/ratio) will give you...
Using a 8 bit CCD camera and the 120ST @ f/2.5 I was able to record some brightening of the comet nucleus. The images are heavily enlarged and cropped, and...
Hello everyone, I was wondering if anyone knows what the couterweight shaft diameter is on Orion's big Atlas Equatorial. I have a 1906 vintage refractor and ...
I saw Comet 9P/Tempel 1 before and after impact from the SF bay area through a friend's 12.5" Zambuto-mirrored Portaball. We drove up to Lake Sonoma NNW of...

Yup, that's what I saw from Livermore using frame integrating video and a web cam on small aperture refractors. Cool, but hardly fireworks, as it were. ...
I just bought a 120ST from Orion - I got the OTA and mounted it on Orion's AZ-3 alt-azimuth mount. I already have a number of larger, heavier GOTO scopes, so...
Hey all. 1. Post here :-)) Now no one here that use Orion scope, how many of you use GOTO/computer on your Orion/SW telescope? And what type/model(number are...
