Pro Bahtinov Masks by Pro Astronomy
The Pro Bahtinov Masks from Pro Astronomy are precision-engineered focusing aids, designed and manufactured in the UK. Leveraging years of astronomical experience and customer feedback, we proudly offer what we believe are the highest quality Bahtinov masks available today. Our current range supports telescopes with dew shield outer diameters from 40mm to 360mm. Need something larger?

Key Features of Pro Bahtinov Masks
1. Adjustable Slots for Perfect Fit
Our Pro Bahtinov Masks feature radial slots and clamps that allow precise adjustment, ensuring the mask is perfectly centered on your telescope. Whether it’s mounted on a dew heater or similar, our mask always aligns concentrically with your optical train for optimal focusing.
2. Premium Fixings for Durability
Most Bahtinov masks come with subpar fixings, but we took it a step further by designing our own. Each mask includes 3 steel thumb screws and custom rubberized feet. This combination offers a superior tactile experience while maintaining both functionality and durability.
3. Precision Laser-Cut Acrylic
We use laser cutting technology to ensure that every slot in our Bahtinov Masks is perfectly straight and parallel. This precision guarantees the sharpness and brightness of diffraction spikes, providing you with the clearest focusing results.
4. Secure Rubberized Clamps
Our rubberized feet securely grip your telescope’s dew shield without causing any damage. The three-point fixing system also ensures that the mask remains firmly attached, even when slewing or during windy conditions.
5. Size Identification for Convenience
For users with multiple telescopes, we’ve made it easy to identify the correct mask. Each mask is laser-etched with its compatible dew shield size, saving you time when setting up.

How to Use Your Pro Bahtinov Mask
- Attach the Fixings:
Insert the 3 steel thumb screws through the radial slots of the mask and secure them with the rubber grips. Position each fixing evenly for a balanced fit. - Adjust to Fit Your Telescope:
If you have the 40-70mm model, positioning the screws at the innermost slot fits a 38mm dew shield, while placing them at the outermost slot fits a 72mm diameter. Each mask accommodates dew shields 2mm smaller or larger than the specified size. - Secure the Mask:
Once positioned, tighten the top two screws securely. Leave the bottom screw slightly loose for easy removal, or tighten it for added security in windy conditions or during extended use.

Don Rudge –
I was sent a New adjustable Bathinhov mask to review by Rob at Pro Astronomy. It came well packed and covered with a protective film. When you get the film started, it pulls off very easily.
It’s a very well made piece of equipment, I dare say it could survive being accidentally dropped. What makes it special is that it’s designed to fit multiple sized scopes. The one I have is for scopes from 100mm to 130mm. There are three fittings that you adjust to get a tight fit for your scope. All that I could add is that ideally there would be some gradient lines so that you could ensure it was centered on the scope.
Now I’ve never used a Bathinhov mask before, but as you can see from the images, the results speak for themselves. Very impressed, good quality and easy to use.
