已自青山处订购:
用途: 配西瓜冲一下极限倍率。 配ES127做深空目视
Ethos
100° & 110° Apparent Field Eyepieces
6-mm | Model # | ETH-06.0 | Focal Length (mm) | 6 | Barrel Size (in.) | 2" & 1¼" | Apparent Field of View (deg.) | 100 | Eye Relief (mm) | 15 | Weight (lb / oz) | 0.97 / 15.5 | Field Stop (mm) | 10.4 |
Delos 戴勒斯目镜有固定的20mm出瞳距离和72度的视场。 提供了极佳的对比度和观测舒适度。
Plössls
50° Apparent Field Eyepieces
8-mm | Model # | EAP-08.0 | Focal Length (mm) | 8 | Barrel Size (in.) | 1¼" | Apparent Field of View (deg.) | 50 | Eye Relief (mm) | 6 | Weight (lb / oz) | 0.11 / 1.8 | Field Stop (mm) | 6.5 | [url=]Compare to similar focal lengths[/url] |
The 25mm, 20mm, 15mm, 11mm and 8mm Plössls round out the focal lengths for various observing from deep sky to planetary. They work best with Tele Vue Powermates to effectively double the number of focal lengths in your collection. Far superior to eyepieces usually provided as standard with most instruments
=============================================================
至此, 我的目镜系统基本成军(用途:深空漫游,太阳系翱翔,月球漫步):
注解:西瓜的极限倍率是西瓜说明书上标注。ES127的极限倍率按口径3倍算出,这个和环境关系大。3倍应该是理论极限了。考虑环境因素, 可能极限倍率在2-3倍口径之间。 即:254倍-381倍
====================
致谢:
-1-感谢昆明苏搭配了大部分配置
-2-感谢青山(iTelsscope)耐心讨论,使我确定了补充配置。
======================
现在的配置感觉比较满意了。 但是还有个小蛮腰情节。 期待实战后确定。
