Another good example of the AT65EDQ�s capability in the hands of an experienced astrophotographer is Jeremy Vandermeer�s image of the Rosette Nebula, also found in the feature images links below. 另一个好例子AT65EDQ�s能力的手中的一名有经验的astrophotographer是杰里米Vandermeer�s形象的贴花星云,也发现,在功能图像下面的连接。It was taken from the light-polluted suburbs of Chicago. 它已经从原来的light-polluted郊区的芝加哥。Jeremy combined 47 separate 240 second exposures taken with a modified Canon T1i to produce the final image, which we think compares quite favorably with professional images taken with much larger and more expensive scopes. 杰里米联合47分开240第二暴露采取与改性佳能T1i产生最终的图像,我们看比较相当顺利地与专业拍摄的照片与更大更贵的范围。Jeremy said about the AT65EDQ, �this scope is great." 杰里米说有关AT65EDQ范围,这�真的是太棒了。So is Jeremy�s image.所以是杰里米�s的形象。
Can you take images as good as these with a 65mm scope? 你可以帮我把图像一样好这些与65mm范围?At the low price of the AT65EDQ it won't cost you a fortune to try your hand at wide field astrophotography.在较低的价格AT65EDQ它就不会花你一笔财富来试试你的手在astrophotography宽领域。
Other manufacturers often use FPL-51 ED glass or its equivalent in their more-expensive triplet designs to keep their manufacturing costs down, or use FPL-53 in a simple doublet. 其他制造商通常使用FPL-51艾德玻璃或等价物的他们的more-expensive三线态设计来让他们的制造成本FPL-53下来,或者使用在一个简单的上衣。In comparison to this approach, Astro-Tech uses a more-expensive true FPL-53 ED (Extra-low Dispersion glass) element in the triplet objective lens of the modestly-priced AT65EDQ. 这种方法相比,使用一个more-expensive Astro-Tech真实FPL-53艾德(超低色散玻璃)元素在目标透镜的modestly-priced三线AT65EDQ。The result is the finest possible control of spurious color, for images that are free of all vestiges of the annoying faint color halos around bright objects visible in lesser scopes. 最好的可能结果是假的颜色,为控制所有的照片都是免费的恼人微弱的痕迹颜色晕周围亮的物体可见在较小的范围。In addition, a fourth lens of a proprietary ED type acts as a field flattener for wide field imaging.此外,第四个镜头的一个专有的艾德类型作为一个领域为广大flattener场成像。
Those exceptional optics are even more impressive when you consider the package they come in. 那些非凡的光学,则更令人印象深刻,当你认为包装他们进来。The finely-machined AT65EDQ has a dual speed 2" rack-and-pinion focuser with a microfine 10:1 fine-focusing ratio. AT65EDQ有双重的finely-machined速度2”与超细10:1齿条式齿轮座fine-focusing比率。The standard equipment camera angle adjuster rotates a full 360� for the most pleasing photographic compositions. 标准设备镜头角度旋转360�满调节器为最令人愉快的摄影作品。The supplied 2" and 1.25" accessory holders use non-marring brass compression rings that won�t scratch your accessory barrels.提供的2”和“附属持有者使用non-marring 1.25黄铜压缩环�t挠你赢得附件桶。
If this Astro-Tech AT65EDQ was simply a top-quality 65mm FPL-53 ED doublet system, it would be fairly priced. 如果这仅仅是一个Astro-Tech AT65EDQ 65mm FPL-53艾德上衣、高质量的系统,它将是公平的价格。But � a 65mm fast focal ratio quadruplet astrograph using true FPL-53 glass, with a dual-speed 2" rack and pinion focuser and a built-in ED field flattener at this price . . .但�quadruplet 65mm焦比一个快astrograph FPL-53使用真正的玻璃,以一个dual-speed 2”齿条和齿轮座和一内置艾德领域flattener这个价钱。。。is the kind of super value only Astro-Tech can give you!是一种超价值只有Astro-Tech可以给你!
