Just an observation. Don't you believe that every new eyepiece offered to the market today has been "computer designed"? I would even go so far as to imagine...
Probably true for the last 30 years, but Geoff pointed out that older eyepiece designs were pretty much devised by trial and error. I suspected as much, but...
Baader Hyperion eyepieces are often mentioned as reasonably priced, good quality eyepieces. I have never seen one so I checked Baader's website for info and...
It is this type of commitment to quality that sold me on the Baader Hyperions as opposed to the Orion Stratuses. They are mechanically very good and I have...
Under mediocre seeing conditions the Hyperions will perform quite well compared to premium EPs. Once I compared my 13 Hyperion to a 12 T4 and really "saw" no...
... Hi Jud, What I think you might be alluding to is that often an entire region can be tagged as having poor seeing because of the jet stream location, but I...
We now know that the atmospheric turbulence that creates seeing is concentrated in two layers: one that is many kilometers up and not strongly influenced by...
John: Have always wanted to visit Australia and have communicated a bit with John Rombi, but he has dropped off my Astromart Radar screen, although he is still...
I have a black Celestron C90 f11/1000mm spotting scope the one with a gold band. I like to turn it to an astronomical telescope. But the trouble is it is hard...
... I would be nervous drilling into the scope, too. A better solution might be a Rigel QuikFinder. These can be attached with double-sided tape (included)....
Jud, I do not disagree withanything you have written. I am in North East Maryland and our seeing is usually a 2/5 (poor) on the clear sky clock and I...
Tim Used to live in Columbia Md, but was focussed on my family with 3 children at the time; even though I had a 6" RV6. So, not sure what the sky was like at...

Actually, after thinking about it - $34 for a 50mm achromat plus a 20mm plastic "Plossl" isn't too bad. I must be getting tight in my old age! LOL! Rick...
I have a 12" lightbridge and was wondering what collimating system would be best for this type of scope. Any advice would be much appreciated, Kenny...
... Personally, for my 11" f/4.3 Newtonian I use a set of Tectron collimation tools: sight tube, Cheshire, and autocollimator. I gave up on using a laser...
I've got to agree with Geoff here, i have the Tectron collimation tools and a 12" L/B and i find that these are far more accurate than the laser alone although...
I second the autocollimator, I use it to check/adjust collimation every time before viewing. I haven't used the sight tube and Cheshire since the initial setup...
... Hi Kenny, I agree with Geoff. If you are only going to own "one" set of collimation tools the Tectron Tools are excellent and what I would recommend. I...
... That's exactly my recommendation, too. I used an Orion collimation eyepiece for many years and was very happy with it. My preference now for the Tectron...
... Hi Geoff, Such comments as yours and my own experience with the collimation cap have kept me from putting the Tectron tools at the top of my priority list....
New member intro, longish… My 10yr old daughter pulled me back to the stars. History: Growing up I wanted a telescope. Large family, tight budget, and no one...
... Got some really good news for you: You've already done the hard part of the job. Collimation will be easier than the refurbishing was. I'll leave it to...
... Welcome to the passion, I didn't get my first scope until I was 55. Everyone has their own take on eye pieces and many know much more than I do but here is...
When you buy a telescope eyepiece do you always have to spend more for better quality? Im looking at an orion stratus wide-field eyepiece,Its 68deg. field of...
