(From time to time I am asked "Will it work/Could it mount on my X telescope?" for various values of X. Well if I had an X, I would make it work. You could send me an X! But it's cheaper if you make a simple adapter plate - If you don't…
This is a modified mounting plate of 1.25" Crayford Focuser for telescopes by aeberbach for use with Hadley telescope. This focuser is a massive upgrade in functionality compared to any printed helical focuser. Attaches to the Hadley UTA…
I am proud to present to you “ Hypatia ”, my take on a focuser for the Hadley Telescope ecosystem. It combines what I consider to be the best features in other designs, and some ideas of my own: the Crayford style of focuser - which uses…
V2 3D printed 1:10 reducer for crayford focusers Update History 2) Integrated needle mod and V1 small button alternative - Integrated needle mod within original file. You can still like and download here or from remixes list. - Added…
Die Kugellager werden im Gehäuse mit DIN 914 M5 x 40mm Madenschrauben befestigt. Die Kugellager sollten 5 mm Innendurchmesser, 10 mm Außendurchmesser und 4 mm Breite haben. Für den Antrieb wird eine 4 mm Stahlstange verwendet. Um eine…
Crayford Focuser 2inch by jackleone12 - Thingiverse Found this focuser over on Thingiverse and re-engineered it for the Hadley project. It is far superior to my rack and pinion design, smooth operating with no grind or slip at all. Has…
3D printed 1:10 reducer for crayford focusers Update History Update 2 : V2 now available here : V2 Crayford Focuser Reducer 1:10 Update 1 : Added a fillet on the reducer support + added all step files Informations The exact reduction is…
2 inch focuser for telescopes, 72mm tall + 26.5mm travel. So far the only mounting plate is for GSO 6" Newtonian tube, but if you need another, drop me a message and I might be able to help. Or you can change dimensions in the first 2…
As a beginner, it was difficult for me to work with a self-printed focuser. I therefore designed an adapter for a Crayford 1.25 inch focuser, which can be bought on Aliexpress or Amazon. The adapter can be installed instead of the…
Update (04/05/26) - fixxed eyetube on very short version to have the thumb screw m4 insert hole in the correct place. Update (01/05/26) - Added new very short version for the Travel Telescope V3.0 only (due to the mounting points being to…
This is mounting bracket for a NEMA17 motor to attach to the Crayford focuser on the Celestron Omni XLT 150/750. My understanding is that there is little standardization on Crayford focusers, so this would likely have to be modified to…
Remixed the main button so it can be installed on a Skywatcher Crayford focus button. If you want really smooth operation, check out the anti-wiggle needle mod here:…
No modification is done to the Hadley UTA. Pick all components from the Crayford reducer V2 except the main button.
Elektronic focuser with NEMA17 for Newton or Refractor with 2" dual speed Crayford 1:10 for OnStep telescope goto controller or my Focuser Hand Controller (FHC) . Wiring diagram and PCB on EasyEDA FreeCad source code on GitHub BOM: 1x…
Remixes the main knob so it can be slip-fitted on a skywatcher ST80 stock focuser knob. If you want truly smooth operation , see the anti-wiggle needle mod here :…
Original model and build instructions here: https://marcosatm.com/2020/06/04/2in-crayford-focuser/ This is based on the nut version as I found the heatserts for the bearings difficult to get right. I've added a lug to secure the reduction…
The small button has a bit of wobble in the original version . The wobble is reduced to almost zero if you add a common axis to all the pieces. Operation is even smoother ! Adds a through-hole for a smooth axis (like a sewing needle)…

This is an reinforced version of the original model. The base plate has some additional supports. The original Model can be found here: https://www.thingiverse.com/thing:4424419
See the instructions on the original.
Adaptor plate to mount crayford focuser to the Orion StarBlast 4.5 reflector. Adaptor Plate mounts to OTA with factory hardware. Crayford focuser mounts to adaptor plate with M3 screws and heat staking threaded Inserts Crayford focuser…
If you find my designs useful, please consider sending a tip The standard backet that comes with the ZWO EAF (Electronic Automatic Focuser) wouldnt line up with the mounting holes on my Astro Essentials SCT Crayford due to the large…
Remixes the main knob so it can be slip-fitted on a Bresser Hexafoc Focuser. Tested on Bresser AR102s/600 refractor but it should be working for any Bresser Hexafoc 2.5" Focuser (?)(TBC). Adds an attachment plate that fits the focuser…
Updated to: Use a smaller diameter main knob for more clearance from the diagonal on a C5. The new main knob is the same diameter as EleusisT's original. Use snap fit connectors to secure the reducers' support to the secured base plate.…
It is difficult to mount a focus motor on Lacerta Crayford focusers, because no free threaded holes available, but I figured out how to do so! This part grabs onto the housing of the focuser shaft, and holds the motor firmly in a very…
The subject of the project is an upgrade that changes the way lenses are secured in the focuser. Instead of locking the lens directly with an M3 screw, I have implemented an indirect locking method, similar to that used in focusers with a…
Spare part rubber for focusser wheel for a Skywatcher Focusser like on Dobson Teleskop N 200/1200 Skyliner Classic DOB. Diameter 40 mm, width 12 mm, FreeCAD model is available to adjust the size to your demand. Glue the rubber to the…
Remixed the base to fit my XT10 telescope.
Taking dark images with my Newtonian telescope in daylight with just the telescope lid on was impossible - the result was a very bright light and overexposed picture. When I investigated where the light was coming from, I found that it…
The iconic 1:10.24 crayford reducer meets the iconic public domain Benchy, when you want fine rotation for your boat. If you use a non-reduced telescope checkout the original model by EleusisT :…
I modified part of the design to mount a dual-speed focuser on my Newtonian reflector telescope. Additionally, during the modification, I added M4 screw holes to the bottom of the focuser for easy attachment of the EAF. Note: The attached…
A while I ago I made the https://www.printables.com/model/125438-125-crayford-focuser-for-telescopes model and it has been popular. But I wasn't that happy with the 3D model, way too many little things patched up or added in a later…
I like Marci's Hypatia Crayford focuser, its great, but when I built mine I only noticed half way through building, it needed 2x brass bushings, which were £9 for 4 so pushed the project price up and would have delayed the build. So I…
I made these models to use with MyFP2ESP32Focuser, a DIY focuser that can be used with NEMA17 motor Update (30th April 2026): I ditched the old design which still used the Crayford design and made the whole camera assembly slip under…
This project allows an electronic focuser to be added to suitable Astro Essentials crayford focusers. The 3D printed parts consist of the housing/mount for a stepper motor and the 4Tronix stepper motor driver board. The 4Tronix Focus RFU…
On an 8" Newtonian telescope I inherited and now use to do variable star photometry, there's a gap between the focuser and the telescope tube -- this focuser probably wasn't meant for this telescope. Not to worry, a 3D-printed part can…
