Hello ! Eric from Celestron and filippo.bradaschia sat down to present something we are really proud of: a that does not ask you to choose. Visual observation, planetary and lunar imaging, deep-sky astrophotography, all from one alt-azimuth setup, with no equatorial wedge.

Motorized focusing, ARCO field de-rotation, PLAY imaging software: you start simple, and you grow the system as far as you want to go. Your telescope, under your control.

The wait is over: "Alt-Az: It's About Time" is finally online! 🎬
This is just the beginning of the story. Filippo Bradaschia and Eric activate ARCO, and a normal night turns into a journey back to 1996, the year alt-azimuth hit a wall. What happens next? You will have to watch it to find out.

In 1996 first CCD cameras reach amateur . But digital sensors reveal every arcsecond of field rotation. Alt-az becomes a dead end, and everyone moves to equatorially mounted . But what if it never really failed? What if we were just missing the technology to do it right?

Watch the official trailer of "Alt-Az: It's About Time", the film by PrimaLuceLab with Celestron. Two friends, one , and a journey back to the night it all went wrong.

Big news from Tenerife! We installed our OUTPOST 3M dome at the ASTRIgamma Mini-Array, in the astronomical site of the Teide Observatory, on the island of Tenerife (Canary Islands, Spain).

The Istituto Nazionale di Astrofisica (INAF) asked us to protect and host a Lidar instrument used for the calibration of ASTRI, the gamma-ray observatory that studies among the most violent events in the .

We assembled and tested the dome in Italy, then shipped it pre-assembled in just 2 parts, so the installation on site was simpler and safer, even in a remote high-mountain location.

We tell the full story, step by step, here:

The Space Koala tested our SESTO SENSO 3 SC focusing motor against our ESATTO 2" LP low profile focuser on her Celestron EdgeHD 8" — and shared the results!

SESTO SENSO 3 SC motorizes the native internal focuser of the EdgeHD, for a simple, non-invasive, and affordable solution.

ESATTO 2" LP replaces the internal focuser with a complete motorized focuser, allowing you to lock the primary mirror and eliminating mirror shift.

Which one performs better for ? Watch the comparison to find out:

Look at this stunning lunar image captured by Gary Varney with a Celestron CPC Deluxe HD 11" powered by PrimaLuceLab!

You can see three of the most iconic fractures on the Moon in a single frame: Rimae Triesnecker, Rima Hyginus and Rima Ariadaeus!

Camera: PlayerOne Mars-M. Barlow: TeleVue Powermate 2.5X.

The sharpness and level of detail you can reach with this setup is fantastic. And this is with a telescope you can use also for visual and deep-sky astroimaging without the need of an equatorial wedge!

We had an amazing time at inside the Celestron booth, showcasing something truly exciting: the "CPC Deluxe HD powered by PrimaLuceLab" !

A huge thank you to David Farina from Cosmos Safari for the interview!

We revealed how integrating our devices and PLAY software with the CPC Deluxe HD 8", 9.25" and 11" models creates a system you can use for visual, planetary and deep-sky — no equatorial wedge needed!
This is what happens when two passionate teams join forces for the love of the night sky.

Hello ! We just had an incredible time at NEAF 2026, the world's most important and expo! In this video, Filippo Bradaschia and Thomas Bramwell walk you through everything we presented at the PrimaLuceLab booth, and there were some big surprises!

We show you the takahashiamerica dual telescope rig, fully modified with ESATTO focusers, ARCO rotators and EAGLE computer. We worked directly with the Takahashi factory to design the perfect adapter for the Epsilon line (130, 160 and 180).

We introduce the complete SESTO SENSO 3 lineup, our focusing motors now with encoder in three configurations: for external focusers, for SCT telescopes, and for photo lenses. The encoder means no more recalibration after manual adjustments!

Then we reveal the SATURN HD-20, a brand new mount born from our space industry work! Strain wave motor with belt transmission, dual encoder, weatherproof with ceramic treatment and 19°/sec slew speed. It was originally developed for ourselves, but after the incredible interest we received at the show... we'll see!

And finally we move to the Celestron booth to present the CPC Deluxe HD telescopes powered by PrimaLuceLab! A complete solution for visual, planetary imaging and deep sky astrophotography on an alt-azimuth telescope, no wedge needed. With the ARCO field de-rotator and PLAY software, you can guide and shoot exposures, stack in real time, and enjoy a telescope that does everything while remaining simple to use.

All the information is already on our website!
