It is a great accomplishment of this test that a Binoscope using a pair of SWAROVSKI-ATX95 is proved to be definitely possible.But the back-focus available is rather short and we should trade off some conditions.At first, 31.7mm(1-1/4inch) adapter sould be made low profiled, and the dust filter should be eliminated so that the end of the eye-piece barrel will not hit the filter.Still doing this the focus margin is so small of a few milimeters, that some of the eye-pieces might not make focuses especially when the user has a strong myopia.So the “A” in the left photo should also be cut short by 6mm or so. But if A is cut short by 6mm, this EMS will have direct connection only with Swarovski.
It may sound that this title is not related to binoscope making, but it is.It is very important for the TOA150-BINO in the making, which is to be loaded on the LX80 and will be linked to SkySafari via SkyFi.The trouble I had found is the wrong directions of the movement of the target cursor in the screen of iPhone/iPad on SkySafari.My friend who is an excellent digital engineer has just discoverd a wise way to evade the annoying bug of the AudioStar controller.He has uploaded a video in Youtube, but I am sorry that he spoke in Japanese only. I is rather difficult to instruct it even in Japanese, but I will do my best in English now, to share this precious accumplishment with my dear astronomy friends in all over the world.
1. Never use the fastest rate “9”. 2. Set the speed to the moderate level as shown in the video on the screen of Skysafari. It coincides with rate”6″ in the AudioStar controller. 3. Then tap the four direction buttons in the screen of SkySafari in turns. You will find odd directions in the lateral ones. But never go panic now. 4. Then, take the AudioStar controller and set the speed rate as “6”, and push every direction keys in turns. 5. Now, return to the SkySafari again, and tap the direction buttons on the screeen again. You will find the right directions of the cursor now!! After doing this process, you can choose the speed level from 1 to 8 (except for 9) at the AudioStar, and you will find no bug even in SkySafari.
EMS-UXL with large Helicoid Set for the TOA150-BINO is completed.In the case of EMS-UL, the first mirror is identical in size with the second (eye side) mirror. While, in the case of EMS-UXL, the first mirror is far larger than the second.You can compare the seizes of the mirrors in the left photo. The novice would not tell the difference of the first mirrors in just watching stars through them, but actually the larger the better is the first mirror.
