Now, it is the moment that I had a confidence in loading the LX80 Mount with the TOA150-BINO.There seems to be no sign of suffer of the Mount with the heavy loading.
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.
TOA150-BINO is almost completed in my mind, because the most difficult process is successfully completed.Isn’t it amazing that just four rings will make up the frame-work of a large Bisocope?
