Here are the details: * Tube outside radius: 104.4mm * Tube inside radius: 100.6mm * Radial separation of screws on the tube's surface: 45mm * Axial separation of the screws: 31mm * Focuser tube OD: 42mm Keep in mind that your scope tube and focuser...

Warning: A motorized focuser such as this does not detect when your focus has been turned to the limits, using a motor to drive beyond the limits will likely damage your telescope. ...A close focus should be achieved by eye and a focuser used for fine...

Has a flat mounting plate as my dobsonian has a flat attachment point for the focuser. Set screw for the eye piece can be whatever you can thread into it. There are no threads in the set screw location. Works a treat for me. Hope you it works...

1.25 inch focuser for Dobsonian telescopes features a versatile mounting system that allows users to attach it flat or in a tubular configuration. The focus stroke is designed to deliver precision, with a 30 mm travel range. Engineers have carefully...

This is a replacement grip for the focuser on a Celestron C-14. I tried it on my Meade LX90 and it fit also, so it may be more universal. ... I use TPU when printing it.

A helical focus adapter made pecifical to mount a SVBONY SV161 1.25 inch Double Helical Focuser to an Orion Starblast 4.5 114mm Newtonian telescope. it might work with other similar telescopes. This is meant to mount the SV161 that has m31...

After removing the 1.25" eyepiece compression retainer in favor of a 0.8x reducer/flattener it was possible for the focuser to travel too far into the main OTA. ...This ring prevents that.

I created a GSO focuser sleeve, because the original one I had, broke. It contains 2 sleeves, one for right side (original) and second for left side. ...You can swap sides of microfocuser handles.

I needed a dustcover for my Explore Scientific Refractor Telescope, good thing there is 3D printing :)M68 x 0.75 thread for Hexafoc or maybe other focusers Print it in 0.1mm layer height for a clean thread

This is the story of myFocuserPro2M DRV8825 focuser controller, built from scratch on the project at https://sourceforge.net/projects/arduinoascomfocuserpro2diy/files/myFocuserPro2M/. The printed circuit board can be downloaded from...

This is a focuser for a Celestron C11, using: - 1 Nema17 Stepper motor - 2 M4x 20mm Hex Head Screws and - 2 M4 nuts for the lateral screw holder - 2 M3x10mm screws with nuts for case holding - 2 M3x10mm screws for stepper motor - 2 M3x5mm screws with...

The controller is based on anat's Leonardo-based controller, found here: https://www.cloudynights.com/topic/594658-pnp-focus-the-simplest-ever-arduino-focus-controller/. I used the NEMA 17HS13-0404S-PG27 motor that anat referenced in his post and...

Probably yes and due to the fact that your equatorial mount is not as stable as you expected and just by touching the manual focuser, you get a very shaky image in your eye piece. You can find here details about my project. I added also a 3D STL...

... software used for this focuser is Ardufocus, developed by J.Brazio, whose work is greatly appreciated. The Arduino is connected to a Raspberry Pi via Ekos/Kstars/Indi software, facilitating seamless control and automation of the focusing process.

... perfectly suited for seamless integration with the 28BYJ-48 motor. Meanwhile, the focuser gear sports an impressive 40 teeth, accompanied by a 4mm screw hole and a 9mm rear hole with a precision countersink to ensure effortless centering.

An adapter from Thingiverse connects the camera to the focuser tube, fitting perfectly on its 32mm OD (1.25" approx.) but not compatible with standard 1.25" or 2" lens mounts. Print settings include rafts, supports, and a 0.1mm resolution. The...

This is the box I'm using for my focusers. They are based on Ardufocus (https://ardufocus.com/). This specific build uses: - Arduino Uno - "Driver" ULN2003 - Stepper motor 28BYJ-48 - 4x M4x12 screws with nuts - 4x M2 screws for fixing boards to the...

### The Focusino is an Arduino based, compact telescope focusing device that is homebrew friendly (single sided PCB) which uses simple and easily sourcable components/parts. **Small form factor (51mm x 51mm x 46mm)** Please checkout the Github...

Focuser 1.25 inch for telescope prints with Prusa i3 settings optimized for precision. Printer resolution is set at a precise 0.2 mm to ensure crisp details. ...Infill density is carefully adjusted to 20% for added strength and reduced material usage.

The focuser is designed to fit any standard 1.25" telescope or instrument. For a 2" version, please visit http://www.thingiverse.com/thing:1904663. ... Print Settings: - Printer: FF Dreamer - Rafts: Not required - Supports: Not necessary - Resolution:...

This is a precision-crafted bracket I designed specifically for motor focusing with my telescope, tailored to fit the Skywatcher Startravel 102 focuser like a glove, holding a Nema 17 PG25 stepper motor securely in place. The design may also work for...

Focuser for the Meade Polaris 127 the original one is bad, the Bore is conical, and only one bearing surface. Result: the Eyepiece wiggles New design: Straight Bore, three bearing surfaces. As for the bearing surfaces, you will need expended...

The coupler has a mechanical fuser (4 thin long bars) that helps to avoid physical damage of the telescope focuser in case of end point is reached (no limit switch was used). No nuts were used, all bolts were heated and screwed into the parts. The...

Every manual focus lens features helicals for its focusing mechanism. If your lens front element does not rotate when focusing, it is likely that your lens has two sets of helicals - one with left-hand turn and the other with the more conventional...

This support enables mounting a stepper motor onto a scope, making it possible to fine tune focus using an Arduino without physically touching the scope and risking vibration issues. To achieve this setup, I've employed rubber bands to securely...
