Jill,
I heard Jerry, SBAU President, had sent you a reply already on this, but here and attached are some Celestron info in case his recommendations on eyepiece placement distance did not work (you are using a diagonal with the eyepiece, correct?).
Chuck McPartlin and I tried to help you set up your scope at his driveway, a while back.

If you still need help, please feel free to email me at tomcez @ gmail.com or call at 562-8795. Tom Totton

From the Celestron EdgeHD Series manual for OTA's (see attached file) this is the part about focusing and locking the clutches, so read it carefully.

"Focusing
Your telescope's focusing mechanism controls the primary mirror which is mounted on a ring
that slides back and forth on the primary baffle tube. The focusing knob, which moves the
primary mirror, is on the rear cell of the telescope just below the star diagonal and eyepiece.
Turn the focusing knob until the image is sharp. If the knob will not turn, it has reached the
end of its travel on the focusing mechanism. Turn the knob in the opposite direction until the
image is sharp. Once an image is in focus, turn the knob clockwise to focus on a closer object
and counterclockwise for a more distant object. A single turn of the focusing knob moves the
primary mirror only slightly. Therefore, it will take many turns (about 30) to go from close
focus to infinity.
For astronomical viewing, out of focus star images are very diffuse, making them difficult to
see. If you turn the focus knob too quickly, you can go right through focus without seeing the
image. To avoid this problem, your first astronomical target should be a bright object (like
the Moon or a planet) so that the image is visible even when out of focus. Critical focusing is
best accomplished when the focusing knob is turned in such a manner that the mirror moves
against the pull of gravity. In doing so, any mirror shift is minimized. For astronomical
observing, both visually and photographically, this is done by turning the focus knob
counterclockwise.
Mirror Support Clutches
The EdgeHD Optical tube is equipped with mirror tension
clutches to help support and minimize lateral movement of
the primary mirror during astrophotography.
To use the mirror clutches:
1. Use the focus knob to adjust the primary mirror
to the desired focus.
2. Once in focus, turn the two mirror lock knobs
clockwise until both are very tight and can be
turned no further.
Warning! Once the mirror is locked down, do not turn
the focuser knob without loosening the mirror locks first
.
Although turning the focus knob should not damage the
telescope, undue stress can be placed on the focus mechanisms causing excessive image shift while focusing."

170327 KZSB SBAU radio show 4th Monday, from 9am Sunday 3pm repeat. Baron Ron Herron, Jerry Wilson, Tom Whittemore, Chuck McPartlin.   click on attached file for audio playback.

far from perfect notes:
00:15.642 song: "calm and cloudless night...Galileo used his telescope for the very first time" JerryW, ChuckMcP, TomT not here, should take Yamaha w/ wife on back, he is at high desert.  1st Friday of month AU has speaker, Jupiter 5AU, occultation, Baron-Q's about Sun today, Sean Kelly meeting, Q's during talk?  TomW not seated, Dr. Whittemore, Mcp is backbone of club, Chuck-more like rear end. B-Many outreaches, dont need Totton, kids like space. B-Sun, mostly H, JW-ball of plasma B-one of 4 states of matter, all of this H, in our Sun, 800,000 miles across, 100xEarth diameter. TW-fusion just in core.  B-light we see came from inside. JW-some from surface, electron fall in levels as plasma cools.  B-Sun fusing for 4.5Billion years, CM-3rd generation star B-begin of univ was all H CM-+He, CM-all protons in center, so need pressure to jam protons together to fusion.  TomW-random walk of gamma rays JW-drunkard finding his car.  JW-neutrinos go straight out from the core. B-all this stuff from the Sun may hit our DNA. JW-usually not good mutation.  CM-like throwing piece of metal into car engine.  "Galileo saw craters on the moon..."

14:08.078 Holst, Saturn music.  B-where Cassini probe has been CM-14yrs.  B-power from nuclear RTG. JW-launched over unpopulated areas usually. except for North Korea. Russia over unpop land.  CM-text Q from Tim Crawford, why gamma rays turn into visible light. JW-Sun emits wide range.  Dwarf star G2 is Sun, altho bigger than most stars.  JW-heat is produced by absorption of light and emitted as infrared[?].  B-flares? JW-CME corona mass ejection, throws particles. CM-mag field lines reconnect gives flares. TW-mag field has a source and entry, and out and an in, in on the North, out on the South. JW-  CM-Sun is a fluid ball B-Sun reverses? JW-all the time, mag field lines flip TW-differential rotation on the Sun, 27 days at equator, 36 days at poles of sun, causes mag fields. B-solar wind, we are protected by our Mag field, solar wind affected by Sun mag field?  JW-sun mag field lines split during flares. CM-mag fields extend far out from Sun also, carrying things.  B-Mars? JW-does not have dynamo, metal works well.  TW-Zyman effect of mag field, earth about 1/2 Gauss. 

25:40.959 Holst, Venus...B-all the planets are asleep with this music.  TomW-Jupiter is wild. worked at Lockheed, solar group, missions on sounding rockets measuring solar corona.  CM-possibly micro flares.  JW-very low density. TW-13 electrons ripped from iron, so hot plasma.  JW-leaving electrons behind like luggage.  B-gold particles from Sun?  CM-cosmic rays maybe heavy stuff.  B-neutrinos at speed of light, not stopped.  CM-can go thru 14 miles of lead before stopping.  JW-earth is transparent to them.  but neutrinos changed types between sun and earth.  B-dangerous?  JW-neutrinos postulated by Fermi that are not detectable.  CM-detecting neutrinos now, give warning of a supernova happening.  B-light tsunami.  heavy elements seem grouped together.  JW-earth lumps them together. B-Totton, he's not listening, probably in middle of cactus garden in Palm Springs.

32:40.183 Jean Luc Ponty music.  B-jW sent email about not being able to describe the Big Bang, but some do? JW-singularity, could have been spread over large area in other dimensions, TW-brane.  JW-like shower of sparks from metal colliding.  B-discovering Dark Matter not counteracting?  CM-more Dark Energy forcing things apart.  Dark means we do not know.  JW-may be property of spacetime itself.  B-may come back together?  JW-big crunch  CM-gnab gib, big bang backwards.  B-supernova like?  JW-our sun will not slam together and bounce back like that.  only white dwarf.  B-Helium has 2 protons, 2 neutrons, why fuse to Carbon, not elements inbetween?  TW-short lives of those elements. B-who knows this stuff? TW-quantum cowboys.

39:31.057  star trek Enterprise Tv show theme music "it's been a long time..." B-the Bare Naked Ladies did Big Bang Theory tv music.  B-April 7 Sean Kelly will do talk on space elevators, started by Arthur C. Clarke JW-also sync satellites B-22K miles above.  Asia has also? JW-yes, ring around the earth.  B-need spider web material for elevator string?  JW-stronger than spider silk.  B-carbon?  JW-single sheet of graphene is strongest, maybe rolled into a tube and many tubes together.  B-lots of weight, how far out?  CM-23K miles.  JW-theoretically possible.  B-not a rocket up?  FAA rules on planes to not hit cable?  B-know anything about Sean talk?  CM-probably a rope and someone to volunteer...  B-movie Gravity, toss ball to earth, it will go down?  JW-depends how you throw it, hard enuf, like 17,500mph, it should drop straight down.  B-last 30s, invite folks to join.  CM-1st Fri april 7, 7pm, web page sbau.org, 2nd Saturday star party telescopes.
