Telescope Mirror Flip Flop
Using new Celestron telescopes, how well do mirror locks work to reduce or eliminate the shifting of the mirror? 

There are two specific conditions that affect SCTs with moving mirrors. The first is mirror shift that occurs when you are attempting to focus. The second is mirror FLOP, where the mirror moves as you cross the meridian or change orientation in altitude.

The mirror locks do absolutely nothing to control the shift that occurs when focusing. For visual use, they are not normally employed because you would have to unlock them every time you wanted to change focus.

If you are imaging, the locks are used to keep the mirror from flopping as the telescope changes orientation. For this, they are very effective. Once the mirror is focused and the lock knobs are tightened, the mirror will maintain its position and not flop around as the telescope is moved across the sky. Once you put your camera on and focus, you can move from object to object without fear of the mirror flopping to a different orientation.

Note: As soon as you adjust the focus using the mirror focuser you may introduce a shift in the mirror. The mirror locks do nothing to counter this. The mirror locks consist of small rods that are attached to the back of the mirror assembly and extend into the lock knobs. When the lock knobs are turned, they cause the mechanism to tighten around the shaft to hold it in place. The best way to avoid the flop issue, if you can do so with the back focus, is to use a rear cell Crayford focuser. That way you can lock the mirror into position and leave it there when collimated.

When dealing with flop, it may not be an issue when astro imaging with short exposures summed in a small time frame where the telescope will not cross the meridian or make large changes in elevation.

Singularity Observatory Bullet Clutch & Focus

Master the Bullet Clutch & Focus
There's a bullet inside your telescope and how you master its use will determine the fate of your telescope!

(According to Celestron) The Celestron EdgeHD telescope series have a mirror with clutches to apply tension to a flexible rod attached to the primary mirror support. With enough tension from both clutches, they lessen mirror shift or mirror flop when the scope is moved around in different orientations while in use.

Because they are flexible, the mirror clutches won’t prevent focusing while tightened. However, because they do put force on the mirror, they should be loosened when focusing. Otherwise the combination of their force and the focusing effort may put unequal pressure on the primary mirror, causing it to bind or unevenly shift while focusing. Note: The EdgeHD 14”, like older Celestron 14” tubes, has two regular mirror locks in addition to the clutches. These locks do just that – lock the mirror. They should be used when the telescope is transported, not to prevent mirror shift. Never focus when these locks are engaged - you may damage either the focuser or mirror.

(According to link) The primary reason for focus shift in the SCT design is a result of the mirror continuing to settle when the final focus is approached using clockwise motion of the focuser. This is because the mirror can continue to settle due to the play between the threads of the focuser shaft and the carrier on the mirror. If you approach final focus using a clockwise, you are "pushing" the mirror down. When you stop, gravity will allow the mirror to now settle away from the treads that are pushing it down to the opposite face of the treads so that they are now "Holding the mirror up." The best results with a SCT will be to always approach final focus using counterclockwise turns of the focuser.

For imagers, this "Lifts" the mirror into final position so that play in the focuser is never allowed to occur. The mirror is raised into position so that the mirror carrier on the baffle is always left at the same orientation, an there is no play left for it to settle back from. For visual observers, the added benefit is that approaching focus using CCW turns will result in less chasing focus (inward direction for Refractors and Reflectors). If you overshoot final focus slightly, the eyes normal visual accommodation can easily adjust to refocus the image on their own. I have had the Celeston EdgeHD locks apart and I can assure you that the design, if the locks themselves, cannot cause any mirror shift. This means that the only shift is the same that comes with regular SCTs and the solution is an aftermarket external focuser, or using CCW motions of the focuser to approach final focus (to may not eliminate, but will greatly reduce shift).

Space1 EM Vision

EM Drive Design Key to Vision
Seeing with EM
The SPACE1 EM spacecraft "rocket substitute" invented by Humanoido is designed with the Hyper EM Drive and moves extremely fast at a blinding 232,500 times faster than a speeding bullet and faster than a rocket, so how can one see anything at those high speeds?

The trick to seeing with the EM is to take in all in the directional vector positions using a physical technical of Alt mirroring.

Alt mirrors are placed after the core to differentiate the image streaming by so fast, as to capture a mid stream and garner it to the window for the Astronauts, Pilot, and Commander. Without mirrors, the flight path would be just a blur of incredible speed beyond comprehension and the normal parameters scale of current spacecraft and rockets.

Space1 A Small Mirror of SpaceX

SPACE1 - a Small Mirror of SpaceX

SpaceX was started by Elon Musk with millions leading to billions of dollars in 2002, a full 12 years ahead of Space1 founded by Humanoido in 2014. SPACE1 was funded by Humanoido, working with hundreds leading to thousands of dollars in 2014. Thus, initially, humanoido had to design his private industry space program in unique monetary saving ways. Today, SPACE1 has become a small mirror of SpaceX following the accomplishments of SpaceX in baby steps. The following five small mirror events were developed by SPACE1 :
