ARCO 3" is the larger version of our ARC second resolution rOtator that, thanks to its incredible resolution of 1 arc second per step, is the most precise camera rotator and field de-rotator! The 3” version of ARCO has a thickness of only 23mm and a free aperture of 76.3mm. When used together with an equatorially mounted telescope, ARCO allows you to...

ARCO 2" is the new low profile ARC second resolution rOtator that, thanks to its incredible resolution of 1 arc second per step, is the most precise camera rotator and field de-rotator! The 2” version of ARCO has a thickness of only 20mm and a free aperture of 50.9mm. When used together with an equatorially mounted telescope, ARCO allows you to rotate the...

ESATTO 4" is the large dimensions robotic focuser that we designed for observatory class telescopes or for astrographs that need for large free aperture, like the Takahashi FSQ-106. Compared to the smaller models, ESATTO 4" offers a larger free aperture of 102.2mm, a longer draw tube travel of 35mm and a higher payload capacity of 10 kg, always with the...

This Eagle-compatible power cable allows you to power devices that comes with 5.5 (outer diameter) - 2.1 (inner diameter), positive tip polarity. This cable connects to the 3A port of the EAGLE, with screw connector to avoid unwanted detachment. The cable is 115cm long. By using this cable, you can power devices like SkyWatcher EQ6, HEQ5 and EQ5,...

1,0m Eagle power cable extension cord is used when you need a longer cable to power devices through the EAGLE.

The dew heater is placed on the optical tube to prevent optics dewing. A very common problem especially in winter and in sealed optical tubes, such as refractors or Schmidt-Cassegrain. These dew heaters, 12 V powered, heat the telescope preventing the formation of condensation on the optics. This dew heater for 50mm diameter telescopes can be easily...

If you want to install a guide telescope in parallel to the main one, guide rings offer the simplest and cheapest solution to make this. The Guide rings PLUS 80mm offer a high build quality and all the features useful for this application, allowing you to install guide telescopes such as 60mm diameter refractors. Like all the other elements of the PLUS...

The side-by-side plates allow you to install two telescopes in parallel on the same mount and they are thus useful for both photographic and visual applications. Using these side-by-side plates it's also possible, for example, to install a camera (like a DSLR) in parallel to the main telescope to take a picture of the sky through their own lens. This...

OnAxisLock 50,8mm visual back for SC telescopes with 3,3" thread is screwed directly onto the rear thread present in Celestron C11, C14 or EdgeHD 925, 1100, 1400 telescopes and lets you use all the 50.8mm diameter accessories. OnAxisLock is the accessories locking system that, compared to the one using normal screw, offers a greater clamping force,...

When we install many instruments (for example telescope with guide scope in parallel) on the mount, it can happen that they are too close together, and that some element touches the others. That's why we created the PLUS 20mm spacers that can be fixed between two mechanical elements (such as a plate and the support rings), keeping the functionality of the...

This 1 Kg counterweight allow easier balance of the optical tubes . It can be installed both side, on the front or rear optics of any instrument. ​Dimensions: 65x60mm, 35mm thickness.

OnAxisLock 50,8mm eyepiece holder for Takahashi (M72x1 thread) replaces the traditional eyepiece holder and lets you use all the 50.8mm diameter accessories. OnAxisLock is the accessories locking system that, compared to the one using normal screw, offers a greater clamping force, avoiding any possible flexure (so it's perfect for astrophotography), it...
