Uh-Oh... Tech2000 has been designing things again. But telescopes like to feel new and improved.
We've developed a number of nifties that we found to be unique, useful, novel, and low cost!
So why not make some cool things available to other users, improvers, and builders?


Virgin Teflon Pad Set

Machined Virgin (not the cheap reprocessed) Teflon, that has been long-favored by Tech2000 customers as an upgrade for for altitude bearings. Proven performers on tubes up to 100 Lb. Used also for azimuth bearing pads, then you use three placed under the scope, and cut the fourth one to use as flank-buffers that prevent the tube from rubbing the lateral rocker-box walls.  Set includes #5 brass screws that recess-into the machined pad holes below-surface.  Tip: Once mounted, place a sandpaper strip with the grit facing the pad surface--then rock the instrument slowly until the Teflon pad surface has been abraded to match the bearing face.
Strongly recommended for upgrading the 'stubborn' general consumer Dobsonian telescopes. And new ATM.

3/4 x 2 x 1/4" thk.

DDR-TEF $35 (4-pak)

Trolleys... "Rock~N~Rollers" Automatically tilt to maintain full-contact like train wheels

These support azimuth bases, often used by us in place of two of the three existing pads.
The surface these run against must be capable of supporting the pressure of a roller-contact as-opposed to a pad like above without indenting the surface. Axles have side-thrust washers, so the wheel drums will not drag against the carry-trolley part when these devices move in a circular or otherwise curved path direction, lateral tilt for full roller contact on imperfect surface planes.
Includes elevation washers/hardware to achieve a desired position that can be varied above the surface.
Often partly-recessed in a well that you drill with a 1" flat spade bit.

DDR-TROLLEY-1/2" $25/pair .5x.5" roller 25Lb load ea (if circular path, Ø recommended >12")
DDR-TROLLEY-3/4" $35/pair .75x.75 roller 50Lb load ea (if circular path, Ø recommended >18")

Midrange Altitude Bearings

Very classy-dressy things, install fast and support tubes up to 200LB on high quality needle bearings with hardened races.  The black roller pokes under your altitude bearing surface, the 1/4 thick aluminum disk screws onto the exterior wall (roller protrudes slightly above disk edge to avoid interference with alt. bearing).  Use 1 to 4 as needed to upgrade scopes up to 200LB. We replace the normal Teflon pads on a Dobsonian altitude trunion with these just one at a time, with the rough rule of thumb that each 50 Lb of OTA weight should add one roller unit. And the results are spectacularly impressive! Too many rollers then it's too "loosey-goosey", hence this rule of thumb. Who would not wish to experience tube movement in arcsecond motions without the old sticky-jumps?

DDR-ABM $33.50ea


Replaces two of your existing four altitude pads (front pair or rear pair) to dramatically reduce the stop-stick behavior common in Dobsonian mount pads when attempting to move fine distances.  They really work well!  Bronze rollers on stainless steel axles mounted in Virgin-Teflon, approx. 1/4" thick.  If using a Dob-Driver, you still need two of our regular Virgin-Teflon pads also.  A low-cost and quick way to upgrade beyond Teflon-only  - up to 100Lb tube OTA's.

DDR-VGP  $50/pr


Wipes on Dob bearing surfaces/pads and dries to a non-greasy non-waxy film that will not pick up dust & dirt or get on you and your stuff.  Microscopic colloidal suspension reduces "pad stick" effects.  Great for fine motion at high mags - and Dob-Driver!  3.4oz lasts for years.

DDR-MG  $20

HD Bearings Plus

Kit for Monster-Dobs is STRONGLY recommended at the 150-500 Lb class total weight.
All our best bearing solutions, levelers too, all pre-assembled, and the other wierd parts required for monsters, and has a great manual to guide at every step of install (especially if you are going to use a drive).
Super solution covers all problems!

DDR2HD $299


  The CNC-machined pulley blanks we use for Dob-Drivers turn out to work very well indeed as new altitude bearings for Dobsonian telescopes that we and others build from scratch, or use to upgrade an existing Dob. 3/4" thk MDF composite is easily drilled cleanly or sawn to suit special applications. Center has 1/2" bore/sight hole directly at rotation center, with a pop-in dust cap included. These are flanged around the rim with a flat well in the middle that is .400" wide x .06" deep, which is perfect for 3/8" wide strips of poly or Teflon to keep this bearing on-track while deleting the requirement to use the extra side-pads that are normally required to prevent lateral movement of a scope tube from rubbing side-walls of the mount cradle (rocker box). High-quality black super-penetrating laquer coating, which you can paint over in any color of your choice without concern about heavy-weather exposure durability.  #MAP  $59 ea.

2-piece set Virgin Teflon strips for above, 1/4 thick x 3/8 wide x 2" length, sink the included brad-nails subsurface to set them in-place.  #MAPTEF $35


Some telescopes have only partial ground boards, such as Orion XT.  We offer custom for those who do not wish to fabricate a more robust solid one on their own.  Cabinet grade BIRCH ply, deep-sealed with hard penetrating coatings.  Thickness at center pivot bolt location is 3/4". You specify round or square, dimensions, center bolt hole diameter, and clear or enamel pigment color.  2" leveler feet supplied.

Up to 100LB load $199
100-250LB load (double thick with toroidal hidden lower deck) $269


Dual machined knobs, all etched & anodized aluminum, dual vertical guide rods with Virgin Teflon sleeves.

NEWTONIAN SECONDARY HEATERS units do NOT require spider conductivity or insulating. The cables are insulated very-fine-scale wire "zipcord" with a micro-connector to route thru small holes without re-soldering. The user has a choice of attaching a 9V battery directly in front of the Secondary Mirror Holder (stowing the excess wire inside the holder), or glue-tacking our cable under the Spider edge (making it invisible to the optics), then either a 9V battery or the 12V cords we make for it can be used. Cordless - super convenient - no powerpacks - no setup - no external controller - simple and effective. Auto-shifts power up if 12V is detected. Low cost, use a 9v battery for 10 nights out in the backard, 10 club meetings, or connect 12v for serious all-week star-parties in colder weather! (Auto-Detect). Unlike other dew sytems, just leave it on the scope, cords are not required.

Spiderman's Engineering Notes about the Tech2000 SPIDERZ 3D:
1)  A curved telescope spider vane like this within the lightpath (shown on the left) always gives much-reduced diffraction spikes in an image view or camera. Dramatically improved contrast is of course the desired effect. The optical physics analyses related to this are often called "The Bi-Directional-Vector Lighthouse Effect". 4-vane spiders are used most often, but are the worst for diffraction spikes (unless you actually want 4 rays of light from each star and some people do want that for imaging). 3-vane spiders are better, but still give three diffraction spikes (not as pretty in images as a symmetrical 4-spike pattern). Curved spider mounting however spreads the light diffraction in a way similar to sweeping a flashlight instead of holding it still in one direction, the result is that light is 'spread' and this greatly increases image contrast -- which is the grail that astronomers always seek.
2)  Our addition of another arch dimension in the vane (shown on the right, longitudinal along the lightpath so not blocking any light-pass) creates a few more advantages in our experience. The mass of a secondary mirror holder with its optic payload was traditionally always mounted in Newtonian telescopes with the disadvantage that the center of gravity of this mass was pendular... meaning it has a tendency to flex its position when the telescope is moved up or down (causing collimation problems). Now the mass is much more in-plane with the mounting feet than a straight-across spider vane could ever hope for. Secondly, this arrangement also provides the ability to use sort tube lengths beyond the focuser position, or relatedly, constructing secondary cages for truss-Dobs that have a far shorter length (and weight) requirement just to get the seconadry mirror mounted in position for a focuser. All using the curved vane benefits described above!
3)  Your secondarys' centerbolt can be rapidly centered, shifted-offset style, or rotated depending on users' desire for perfection or experiment, thanks to our oversized internal square tube and its' moveable circular end-clamp-plates seen at label 'C' above.
4)  These spiders are shown in outward-arching aspect. They can be reversed. Could just be straight across arc too if you specify that (item F above).
5)  Vane thickness will vary to optimize for secondary mass and span. Typical .040-.125". Thinnest when larger vane width (longitudinal) is possible. Think like its a large diameter cylindrical tube with the profile shape cut out of it like above... its then very 3D rigid!



So simple it just can apply anywhere required.

ROTACALC!  Field-rotation calculation program for superior imaging with a Dobsonian or other altaz mounting.

Plots the rotation RATE CHANGE (which varies over time and sky position) then finds the best times to shoot longest possible exposures with the minimum possible rotation on altaz mounts or altaz platforms. You input your location, your desired image rotation limit for an exposure, the object designation and its' Ra/Dec cooridates... then out comes an all-night field rotation rate plot and a list of the optimum times to begin exposures for that night.  PC Windows only (it starts itself in a DOS-Prompt window with a doubleclick).

ROTACALC $32  Ships via:  email


1-1/4" long-barrel type machined from aircraft aluminum.
Use a 1-1/4 adapter on 2" focusers (not supplied).
We do supply a user-calibration cradle, tool, and target... no one else does that!
