StellaMira 66mm ED f/6 Refractor Telescope – Premium Travel APO

All StellaMira quadruplet telescopes are QC-checked in the UK to ensure they achieve their full potential.
The StellaMira 66mm ED2 Quadruplet f/7 flatfield refractor telescope produces wonderful, super-sharp, flat-field images, making it an excellent choice for wide-field astrophotography!
Its quadruplet (four lenses) f/7 optical system provides a wide, flat field of illumination with sharp, round stars across the entire field. The fully multicoated optical design also incorporates two ED glass lenses that significantly reduce chromatic aberration.
The native field of illumination is 44mm, so it can be used with camera sensors up to and including full-frame. There is no need to calculate back-focus distance or buy a separate field flattener.
An optional 0.8x Reducer/flattener is available to enable imaging at f/5.6 with sensor sizes up to APS-C.
The sturdy 2.8-inch rack-and-pinion focuser with threaded camera connection features a dual-speed mechanism with a 10:1 reduction gear for super-fine focus adjustments and an integral camera-angle adjuster that lets you quickly and easily rotate your camera to achieve the best composition.
Other features include a fully CNC-machined black-anodised body with knife-edge internal baffles, a retractable dew shield, two accessory shoes, a convenient mounting rail/handle, and a Losmandy-style mounting plate.
Although the 66mm ED Quadruplet is designed for astrophotography, its sharp, high-resolution, well-corrected optics deliver excellent views for visual astronomy when paired with a 2” diagonal and a wide-field eyepiece.

The StellaMira 66mm ED f/6 Refractor Telescope is a beautifully engineered compact apochromatic refractor designed for astrophotography, travel astronomy, and premium grab-and-go observing.
With its 66mm ED doublet optics, this telescope delivers sharp, high-contrast views with excellent colour correction, making it ideal for lunar observing, rich-field Milky Way sweeps, nebula imaging, and DSLR or cooled camera astrophotography.
The fast f/6 focal ratio gives a generous field of view, making it perfect for wide-field targets including Andromeda, the North America Nebula, Rosette, Pleiades, and large star fields.
Premium ED Optical Performance
At the heart of the telescope is a high-quality ED objective using Japanese Ohara ED glass, helping suppress chromatic aberration and maintain excellent contrast on bright stars and lunar detail. :contentReference[oaicite:1]{index=1}
This makes the 66mm an excellent choice for both first-time astrophotographers and experienced astronomers wanting a lightweight travel refractor.
Precision Rack & Pinion Focuser
The upgraded dual-speed Rack & Pinion focuser offers smooth, backlash-free focusing and excellent load support for cameras, filter drawers, and field flatteners. Fine focus control allows precise star focusing for imaging sessions.
- Dual-speed precision focusing
- Excellent for DSLR and cooled cameras
- Strong enough for filter drawers and accessories
- Ideal for wide-field imaging rigs
Perfect for Travel & Portable Imaging
Its compact size makes it an outstanding match for lightweight mounts, harmonic mounts, and portable astrophotography rigs. It pairs beautifully with Player One cooled cameras, ASIAIR workflows, and travel tripods.
- Portable travel APO refractor
- Excellent starter imaging telescope
- Wide-field nebula and cluster specialist
- Ideal for smart mounts and lightweight rigs
For astronomers wanting a premium compact refractor that excels in both visual use and astrophotography, the StellaMira 66mm ED f/6 is one of the finest options available.
