Camera accessories for astrophotography - precision in every millimeter

In astrophotography, literally every millimeter counts. A minimal deviation in distance, a light leak or a skewed coupling can mean the difference between a perfect shot and an unsuccessful session. That's why camera accessories The technical backbone of any successful astrophotography setup.

At Telescope.co.uk you will find everything to optimally couple your astro camera to telescope, filters and correctors - without backlash, light loss or distortion. From adapters and spacers to motorized filter wheels and electronic focusing motors, every part is designed for maximum precision, stability and compatibility.

What is included in camera accessories?

Our collection includes high-quality components that define the accuracy of your complete imaging setup:

• Adapters and extension rings - Ensure the correct backfocus distance between telescope and sensor, essential when using field flatteners or coma correctors.

• Motorized filter wheels - automatically switch between LRGB or narrowband filters without touching your setup.

• Tilt-adjusters and rotators - correct field tilt and help you frame deep-sky objects precisely.

• Thin filter holders and spacers - ideal for fast telescopes (f/4 or faster) where even one millimeter difference is visible.

• Focus aids - Electronic focus motors and Bahtinov masks for razor-sharp focus, especially in narrow-band photography or temperature difference.

Each accessory has been carefully selected to be compatible with the most widely used cameras and telescopes - from ZWO and QHY to Newtonians, refractors and Ritchey-Chrétiens.

Why are these accessories indispensable?

A well-tuned astrophotography setup is like a chain: its strength is determined by its weakest link. Camera accessories ensure that that chain is close.

• Perfect optical distance - Accurately adjusted spacers and adapters prevent stretched or distorted stars.

• Light-tight couplings - CNC-machined precision components prevent internal reflections or micro-movements.

• Efficient filter management - motorized filter wheels make changing filters completely software-controlled, without touching the telescope.

• Compatibility for any setup - connections in M42, M48, M54 and M68 fit virtually all modern astro cameras and flatteners.

These details seem small, but in astrophotography consistency means everything: one wrong distance, and your picture is unusable.

When do you need this?

Once you move from “looking” to “capturing.”.
For planetary photography, a simple coupler is sufficient, but for deep-sky shots with multiple filters or correctors, precision becomes crucial.

Do you use a monochrome camera With LRGB or narrowband filters? Then a motorized filter wheel is essential to change during long exposures without vibration.
Are you working with a coma corrector or field flattener? Then you need distance rings and tilt correctors to get the image perfectly flat especially with large sensors such as the IMX571 or IMX455.

Even a minute deviation of 0.3 mm can be noticeable in the corners of your image. Therefore, well-chosen spacers and adapters are not a luxury, but a necessity.

Compatibility and support

Our accessories are designed for a wide range of telescopes and cameras, including:

• ZWO ASI cameras, ASI1600MM, ASI2600MC, ASI6200MM and other models.

• Filter wheels & adapters, With M42, M48, M54 and M68 threads.

• Telescope types, Newtonians, refractors, Ritchey-Chrétien and catadioptric systems.

Each product on Telescoop.co.uk clearly states which combinations are possible and which distance setting is required.

Frequently asked questions about camera accessories

Why is backfocus distance so important?
The distance between the flattener or corrector and the camera sensor determines whether you see stars pointed or distorted. A deviation of only 1 mm can lead to blur in the corners. Therefore, you use spacers or extension rings to achieve exactly the required back focus (usually 55 mm).

What does a tilt-adjuster do?
A tilt-adjuster corrects a skewed sensor. Even minimal deviations can cause one side of the image to be in focus and the other not. With a tilt ring, you adjust that perfectly.

Do I need a motorized filter wheel?
If you work with multiple filters (such as LRGB or narrowband), yes. It prevents shake and saves time: changing is done automatically through your software, without refocusing.

Will any filter wheel fit any camera?
No, note thread (M42, M48, M54, M68) and optical distance. On Telescoop.co.uk you will find each filter wheel listed with which cameras and adapters it is compatible.

What does a focus engine do?
A focus motor electronically focuses the telescope - crucial in long exposures or temperature changes, where manual focusing can lead to vibration or loss of focus.

Conclusion

Astrophotography is all about control. The better coordinated your camera, telescope and accessories are, the more consistent and sharp your results will be.
With the camera accessories for astrophotography from Telescope.co.uk build you a stable, light-tight and perfectly aligned setup, whether you are shooting with a simple CMOS camera or a fully cooled deep-sky sensor.
