DIY EQ MOUNT V2

Hey everyone! I’m so excited to share my latest YouTube video with you. This time, I’m showcasing Version 2 of my DIY Harmonic Mount—a compact, budget-friendly mount for astrophotography enthusiasts!

In this video, I cover:

The redesigned, all-in-one enclosure

How OnStep makes DIY mounts powerful and accessible

The pros & cons of the V2 design (with real test results!)

A detailed breakdown of the build process and costs

All this for just $399! And the best part? The mount is completely open-source—all the files, designs, and instructions are free to download and customize to suit your needs!

Whether you’re into deep-sky imaging or planetary photography, this mount has a lot to offer!

Curious about how it stacks up to the original version? Don’t miss the side-by-side comparison and first-look at the test results!

    Ho visto il video, molto interessante.
    Due domande:
    1) sul peso servirebbe qualche chilo in più. Un tele con puntatore e guida, una macchina fotografica, magari una ruota portafiltri, un miniPC e un USB hub o addirittura una powerbox e – a meno di usare un rifrattorino – siamo oltre i 10-12 Kg.
    Il progetto è scalabile, in qualche modo?
    2) Il case in plastica non è soggetto a flessione tra i due assi? Gli HD fissati sulla plastica…
    Molto meglio quello in alluminio, sempre che sia bello spesso…
    Comunque, molto molto interessante, complimenti. Spero che tu resti in circolazione, io e un mio amico progettiamo di mettere insieme un setup “da viaggio” e questa cosa sembra fantastica.
    Ti ricontatterò.

  2. What a great project, I already have a Keen-One, that was fully 3d print, but yours look amazing

  3. Nice project, I think the 3D model only includes 1 part of the enclosure without the top cover?
    Is it intentional?
    Also, do you know of alternative stepper motors that could work? Shipping from OMC is very expensive for me, so trying to find cheaper options.
    Thanks.

    1. Any stepper motor with 0.9 deg, 38mm long and nema 17 style will work!/
      Yes I’have to add the top part

      That’s what I got too. Not sure how to print it out without all the parts being included.

      1. Yes, sorry i will post the top in the next days, sorry

    I’ve been really interested in building a mount. Thanks for the videos. What is the PCB way configuration you use to print the enclosure. If I want an aluminum enclosure, do I need more details for the tapped and threaded holes? Thanks so much!

  5. Fabulous project, keenly awaiting trials under the stars. Really appreciate you open sourcing this….

    Hi,
    exacly what i was looking for.
    To use a metal HD seems a good idea.
