正立ミラーシステム(EMS)を開発した松本龍郎のサイト。 たった2回の反射で天体望遠鏡の像を正立像にします。
Tatsuro Matsumoto; Inventor of the EMS, Erecting Mirror System. EMS offers non reversed upright image with no additional undesirable abberations.
Many of you have resumed muscle training in the period of “Stay-Home-Period” by the COVID-19. I am also one of the guys, but I might be very few of them who decided to regain the ability of my youth again at the age of 68. Which may sound unrealistic, but I am serious.
It is a good chance to show you the comparison of the old and new larger-housing of the EMS when the old one returned for the reform. The left one is for the FS102-BINO , now it is at my place, and the right one, in white, is the current larger-housing.
The old one, left TAKAHASHI-colored one made more than two decades ago,was molded in the sand by the traditional method, and the right white one was diecasted by the modern plant which is far more precise and thinner.
You will know by this movie how difficult it was to set the maximum sized mirror into the older housing.
To optimize the IPD range of reformed Center Mount system from the equatorial type Binoscope, I decided to make a pair of 3mm-thick plates to enlarge the maximum IPD by 6mm for the sake of the special situation of the client.
Today, I am going to show you the perfect adjusting model of the binocular viewing and the cross-eyed adjustment which many of the novice would often be trapped in.
If you can adjust EMS correctly, the target will appear in the same positon in both of the left and right field. Try the two images merging into one by the parallel watching. You will find one merged target and also one merged field.
If you are trapped into the cross-eye viewing, you will adjust the images as the photo above. Try the two imaged merging into one by the parallel watching. You will also find one merged target and also one merged field. In the actual binocular viewing the left and right field will not perfectly merge as the photo below. However in the experiment of this way, the field appear a bit behind from the target. Anyway remember that you should always aim at the position of the top example.
This is the typical image of the binocope cross-eye adjusted. I could not show you by the parallel watching of the above images.
