... the screws are designed for M4. The holes for adjusting screws (x2) have been threaded with a tool (M4). The bigger diameter for the adjusting ring must be put face to the camera. If not, the focuser will be thighten and won't be able to turn.

... EAF to the 3" Feather Touch focuser. ... In my case I used it to mount the ZWO AEF (https://astronomy-imaging-camera.com/product/zwo-eaf). It's reversible so you need to orient the holes such that they align with the two screw threads on the focuser.

Celestron doesn't officially support their electronic focuser on the 5SE model so this fixes that. No modifications are necessary to any of the stock telescope or focuser components. Basic instructions are: 1. Print this thing out .. I used...

The dust cap has an inner diameter of 2.25 inches and fits snugly over the exterior of the draw tube on my Moonlite CR 2-inch Newtonian focuser. ...When printed at 100% scale, the fit was a bit too tight, so you may want to adjust your print settings...

After years of reliable service, my focus mechanism's rubber gaskets finally gave way. Determined to find a suitable replacement, I created a custom drop-in solution that closely mirrors its predecessor. ... Inner circumference: 40mm Thickness: 12mm

Protect the focus point with a protective cover, much like shielding the diagonal mirror or Barlow lens from harm. ...A sturdy design features three secure screw holes to ensure a solid hold.

The user-friendly design of this 1.25 focuser makes insertion a breeze, thanks to its cleverly angled bevel. ...Once in place, the secure grip provided by the ergonomic fingerhold ensures a confident removal, every time.

... the drilling of a setscrew hole on the side of the base that must be threaded to accept an M8 screw. An M8 nylon bolt is then screwed into place, serving as a tensioning mechanism and securing the focuser firmly in position when required.

This is a precision focus adjuster for GSO Monorail telescope mounts with 1:10 fine focusing capabilities. The project draws inspiration from the https://github.com/fehlfarbe/arduino-motorfocus codebase, offering a high level of customization and...

I got my scope second hand and it was missing the cap for the focuser, so I made this one that covers the focuser, and 1.25" adapter. There are L shaped slots cut out to go over the set screw knobs so that the cap can be locked in place. Loosen...

This is a remix of part C of the great ZWO OAG HELICAL FOCUSER, adapted to fit the Lowspec spectrograph, https://www.thingiverse.com/thing:2455390. I joined the guidescope tube from the Lowspec to the OAG, and now I can smoothly focus my guidecam...

... a metal gear for the motor 4 M3 bolts to fix the motor on the box and the box on the support. Also 2 M4 bolts for the support on the base. Many arduino projects use step motor as electronic focuser. ... I used EQFocuser and I'm fully satisfied.

Human: I'm building a custom focuser for my Explore Scientific 80ED using a cheap stepper motor and Arduino. The case is designed to be easily clipped on and off. All the necessary electronic components are listed on this GitHub page:...

After experimenting with a couple of existing designs, I encountered issues opening up the C-rings to accommodate my scope's unique shape, which led me to design a focuser that utilizes half-rings instead. Additionally, I was concerned that the...

This is a fine Focuser based on a design from wal20. It uses two #6-32 screws to tension and lock on a piece of steel plate. ...Beneath the ring are a piece of felt to ensure a good lock down.</p> <h3>Print instructions</h3><p>Printed on a Prusa Mk2,...

After years of faithful service, my trusty focuser rubber seals finally gave out. Undeterred, I set out to create a drop-in replacement that would replicate the performance of the original with precision and accuracy. ... Key specifications include an...

The original rubber knob can be placed again on the UpperGearHolder, and to disengage the motor for a rough first focusing, just pull out a bit the ServoSupport4Motor, focus using the knob and then release the motor support and the spring (or a...

The design utilizes two rings from the previous focuser, one ring is modified to anchor a motor securely to the body of the telescope. The motor drives a belt which is attached to the other ring. The belt is secured to that ring by a belt clamp...

 The pictures with this post show one version with the collet nuts for both; and one version with the handwheel main nut and grooved collet nut.The lock-nut is optional, if you threads are tight then it is not really needed, but if you need to...

Then, the gear can be slid back down to engage the fine-focus knob's large gear, allowing the motor to do the final focusing. I'm controlling my motor using a Raspberry Pi 3B and PiFace Motor-Extra board. The control software is the...

The 3D-printed adapter in blue gives an amateur astronomer the opportunity to acquire a cost-effective SCT electric focuser. ...The GSO costs $100, while the Orion electric focuser comes at a price of $69.

This is a support for a step motor (28BYJ-48) to focus on Celestron C5 scope. It comes in 4 parts: - The support - The motor case - The gear - The shaft cap You need some M3 bolts with nuts. 2 M3 (8mm) bolts with nuts in the gear. You put...

Why buy a motorized focuser accessory for astronomical amount of money when you can get high-quality wireless focus motor from the videomaking tech?This was designed for Meade Poalris 127 (~155mm tube diameter) and 15mm rods. Specifically I use...

To assemble the adapter, three 20mm M3 screws are required to secure it into the focuser. Additionally, two M3 screws are needed to attach the 28BYJ-48 to the mount. When attaching the motor to the mount, a 30mm screw was used, but a 10mm screw could...
