This is a Model for Dobsonian 8-Inch Telescope. The Eyepiece Adapter is specifically designed for use with a 2-inch eyepiece. If you prefer to use a 1.25-inch eyepiece, however, you will need to create and install the 2-Inch-to-1.25 Adapter Model...

Focuser mount for a homemade dobsonian telescope with an 8" primary mirror and a 12" tube inner diameter. I included the original FreeCAD file so that the parametric can be adjusted to fit your needs. Uses m6 bolts and nuts for final assembly...

The Fiber Optic Laser collimation tube assembly featured in my Raman spectrometer project is also a Step file, encompassing all its internal components.

Altitude bearings for small Dobsonian telescopes consist of mounting holes to screw onto wooden cradles for optical tubes. The bearing diameter is 150mm; width is 25mm. Light sanding of bearing surfaces may be necessary to remove print artifacts. The...

This is another design for the altitude bearing of a Dobsonian telescope, an improvement over my previous design: https://www.thingiverse.com/thing:2637742 The lever arm of this design is twice as long (6" vs 3") making the balance of the scope less...

**Bench Collimator:** A bench collimator is a more advanced version of the standard collimator. It's designed for use on a workbench and provides more precise alignment measurements than a standard collimator. 3. **Collimation Screws:** These are...

... this tool is placed top of phone or iPad screen. ...The unfocused star is a ball with cross of telescope camera support.Tool is used to confirm, that the cross is middle of the star and there fore the eVscope telescope is collimated perfectly.

(gently, don't scratch your mirror)Install the Cheshire Collimation Eyepiece into focuser.Shine a light into the side of the eyepiece while looking into the pinhole and you should see it in the primary mirror.Adjust the Collimation screws at the back...

... white wall. This is good guide on how to collimate a Newtonian telescope: https://skyandtelescope.org/astronomy-resources/how-to-align-your-newtonian-reflector-telescope/ The Cheshire is used in Step 3. ... Made to be printed without supports.

Poor Man's Bob Knobs Make Tool-Less Collimation of Reflector Telescopes Easy. These knobs fit tightly onto 4mm bolts without any tools required. Simply use three bolts to replace the grub screws that came with your telescope, and you're good to go!

1.25-inch collimation eyepiece is available for printing with no support or brim, requiring only 15 or 20% infill density. It can be printed in single and dual extrusion models, allowing users to print separate components that can later be assembled...

-------------------------------------- A support to collimate its laser (if it is "collimatable" of course) It is intended for 6001 bearings, I took ZZ because they "roll" better, the 2RS with their sealed flanges need more weight to turn well. The...

A 16" Dobsonian telescope 3D model boasts intricate detailing and authentic textures, crafted in Blender using the Cycles rendering engine. ...Customizable color options are available, while the model is specifically optimized for Cycles-powered...

Drop-in replacement for eyepiece racks that Orion used to bundle with all of their XT-series dobsonian telescopes. They still feature pre-drilled holes in the mount for the rack, but no rack is included in the accessories package. ... This eyepiece...

... parts follow on from the two cloudy nights threads. [DIY1]: https://www.cloudynights.com/topic/589521-37-dobsonian-dsc-for-diy-makers/ [DIY2]: https://www.cloudynights.com/topic/753765-diy-digital-setting-circles-wifi-bluetooth-with-2-encoders/

I modified the collimation eyepiece by adding crosshairs and an eyecup, then lengthening the tube. ...The result is comparable to a purchased Cheshire telescope.

A simple collimation eyepiece size 1.25". The center hole diameter is 2 mm. ... You can add inside some reflecting material.

This printable telescope features a collapsible optical tube assembly that collapses into a compact cakebox form protecting the optics, and a sturdy dobsonian mount that can be set up and ready for stargazing in under 5 minutes. The optical tube...

I've continued my previous telescope project, constructing a 12-inch (300mm) Dobsonian truss scope with a shorter focal length of about f6 compared to the initial 10-inch f9.8 version. The modular design allows for easy adjustments in mirror cell and...

Applies to GSO 10" Dobsonians with premium Altitude bearing tension adjustment mechanism Apretura AD10, Zhummel Z10, Orion Sky Line 10" 8" and 12" telescope models of the same lineup will require a different belt and mild redesign of the motor-clamp...

... your telescope. ...Featuring an optional access point, this innovative design can also be utilized as a precise collimation tool. ...The accompanying STL files are carefully scaled for optimal compatibility with 1.25 inch (31.75 mm) eyepiece mounts.

Slide this part onto the collimation tool torx wrench (for the Unistellar eVscope telescope). It is a tight fit. It is easier to adjust the collimation screws using this adapter for the wrench. I printed with PLA on a BiQu B1 printer using Ultimaker...

This mask simplifies collimation of SCT scopes, making it easier to align them properly. It should also work with other types of scopes, but I haven't tested that myself. This design features a "handle" that encircles the secondary retainer. ...Having...

This is a telescope build around a PVC tube. It uses components available in any hardware store, a set of two telescope mirrors and some 3d printed pieces. F=750mm D=150mm F/D=5 This was a 2020 summer project, it took me a lot of time. I do...
