A gathering of friends on a clear March night took place to look through these 3 spectacular TEC APO fluorite refractors. What's a TEC refractor, you ask? Visit TelescopeEngineering.com to see the nice product lineup offered by Yuri and his crew (TEC stands for Telescope Engineering Company).

TECfest Observing Report by Wes Bolin

" q* A, A! a% D( O6 nwww.astroview.com.cnThat was a night to remember. We were in between storms with one clear Saturday night. We hoped the seeing would provide us with the ability to perform high-magnification viewing. A miracle happened; the seeing was really stable. Our primary target was Saturn since we were in a very bright light dome of Plano/ Dallas. I tried some "brighter" deep sky objects with my 160FL, but they were not the right targets for that location. Early in the evening, all three scopes were trained on Saturn: Chuck's 200FL, my 160FL with Baader Binoviewers, and Tim's 160FL in mono mode. I had TMB Monocentric eyepieces in my scope, Chuck had AP eyepieces, and Tim had a variety in his throughout the night. 天文家园欢迎您！1 o$ {  p& _- r( T) Q4 X0 n

' e$ L: A$ \4 ]/ F: }" l$ a/ u天文家园欢迎您！I arrived before dark to set up, and assist Chuck in whatever way possible with his set up of the Big Kahuna. The 200FL is a big scope! He lovingly cradled it in both arms as he climbed the short ladder to place it in the rings, with his wife Deborah on one side and me on the other acting as spotters like in the Olympics. In contrast, Tim's setup and mine were a one- person operation. But the 200FL was a big telescope on a big mount on a big pier, all first class. 天文望远镜器材评测和交流论坛$ H  l1 S, X' P' @

% J$ ?3 y% j4 h" x  n- D4 q天文望远镜器材评测和交流论坛After dark, we started to view Saturn. I have never seen a finer view of Saturn than what Chuck's scope presented. It was bright, sharp, subtle contrast was evident, and it was "big". Aperture wins for sure. We could see 7 moons, the Enke Minima, color shadings on the poles, Cassini all the way around, and beautiful Saturn with a stark black background. More experienced viewers could see many nuances in its image. I started viewing through the 200FL so I could look through the 160FL's and try to determine what was "missing". So, the 200FL was outstanding.

1 z& {; W& K/ HNext, I went to my scope, also using Binoviewers. I don't recall the magnifications, but I think Chuck was over 300X and I was about 275X. First thing I noticed was that Saturn was smaller and dimmer, but surprisingly not too much. The majority of characteristics observed through the 200FL were visible in the 160FL. I just had to look harder, or catch them as they fleetingly came in and out. A friend of mine said that going from a 140 to a 160 made the planets look brighter and easier to see, and thats exactly what I saw between the 200FL and the 160FL. 2 S  v/ ?& d7 E' q8 Q- N

Then I went to Tim's 160FL, in the Mono mode, and could see no difference in Saturn com- pared to mine, taking the Binoviewers into account. His scope's image was remarkable. I had used this telescope at the Eldorado Star Party (Eldorado, TX) last October, on Deep Sky, and it performed flawlessly, so I saw it was the same on Saturn. The thought came to me about the consistent quality that Yuri and crew produce.国内专业的天文望远镜器材评测和交流论坛，致力于如高桥、televue、tmb、ap、tec等顶级望远镜和附属器材% X5 ^( Q" Y: b$ H

One overriding impression is that all three telescopes had the same color images; whiter and pure. There is something hard to describe about the purity of Saturn in all three scopes. Perhaps it has to do with the fluorite... 天文望远镜器材评测和交流论坛+ I; ?1 L$ I6 N* ^- E5 l' E! ?

I am very happy with my 160FL; it fits my needs exactly. I just wish I lived closer to Chuck so I could take advantage of his hospitality to let me look through his 200FL. The 160FL is the best telescope I've owned, and its good to know that its in good company. But, I still dream about Saturn in the 200FL. 天文望远镜器材评测和交流论坛* j. l/ i' h1 b0 v0 F2 G

Chuck thinks that he is not bringing his TEC200 APO to TSP (Texas Star Party), but I have only begun pester him about this, so we will see.

% f. ]& o- G, v# d, `Thanks to John Rudd for trying blind me. He put a low power eyepiece in Chuck's 8 inch, and pointed it at the moon, without any filtering. Prior to looking into the scope, my eyes were pretty well semi-dark adapted. Then I unwittingly (I do that alot) glanced thru that eyepiece. I almost fell into the pool. I guess that I should have noticed the beam coming out of the eyepiece--it was like flying over the Luxor in Vegas. John got a good laugh out of that one. www.astroview.com.cn4 y) c* ^$ x+ D9 b

Chuck's mighty TEC 200FL sits handsomely on an AP1200 mount and a PWT Monolith portable pier. The views of Saturn that evening with the Baader binoviewers and AP eyepieces were truly astounding.

Wes traveled from another state to attend this event, and I'm glad he did. His scope matched the views of Tim's, as expected. I enjoyed getting familiar with his DiscMount.

Jay Ballauer contemplates the possibility of creating a TEC 160FL binoscope. Not really. The truth is as a devoted imager, Jay was struggling to get through the night just using eyepieces. He kept bragging about the eyerelief of his laptop monitor. www.astroview.com.cn6 o! a( J. P; T' v0 |

嘿嘿 通篇读完 有够毒的 要是tec是空气头就好了

狼为什么念念不忘空气头，你对油头不感冒？给个理由先

200里面看到的东西，大部分160里也能看到。这么说的话，还是160划算。

就是更加明亮,细节更容易辨认而已,然而代价是巨大的,重量便携性能和资金确有很大差别

看过漏油的图片 怕了

镜子的口径是无止境的，找一个适合自己观测习惯的sweet point是最重要。

要是突然下起了阵雨，这几个镜子就遭殃了

还是2寸接口的双目好啊,45度都不会自己滑下来

那个游泳池好啊，游了再看，看了又游，边游边看。呵呵……

我更喜欢那里的环境，国内社会的整体素质目前还达不到。
