This item really works, no more chasing focus. Precise focus is achieved in seconds even when using a dew shield. The two plastic screws used to hold the mask in place are simplicityí itself.

Unfortunately I didnít have much of a chance to see how effective this mask is as it blew off my scope and smashed to bits on my patio.
It simply rests on your scope using two nylon threaded bolts so can be dislodged easily.
It may not be so much of a problem if you are using the scope on softer ground.

Absolutely brilliant - Iíve just tried it out for the first time and it really does take the guesswork out of focusing, especially when viewing via a DLSR tethered to a laptop and using Live View on-screen (which is inherently fuzzy and makes focus hard to judge).
A couple of other things: (1) being the clumsy oaf I am I dropped it twice onto a patio from about 1.5m and it survived unscathed (no shattering like other people have experienced). (2) If you canít find the two plastic screws have a good search through the packaging material, theyíll be in there somewhere in a little plastic bag.

Not happy at all with that, dropped it from height of 70cm and split a a part like a piece of glass, and I am not only one who just weasted £19 Why is could be made from durable and flexible plastics? Why?
Sorry to hear your Bahtinov focus mask didn't survive the drop, please return the pieces for a free replacemant :-)

I got this mask and I am quite happy with it. It is well made with thick plastic.
Although I am happy with it, I have 2 minor complaints: The screw to hold it are really hard to push through the holes and I struggled a bit to fit them in. The screws that came with it are white, I wish they had been black like pictured on the website. Does not look as good with white screws
On a side note, it did not come with an instruction sheet. I had seen tutorial on youtube were people had the instructions sheet with pictures for that particular model. Again, really small complaint.
All in all good prodcut for the price!
Works well, but shatters if dropped.

I bought one of these for my 12" Dobo. It works very well, but you should be aware that it seems to be made of very brittle plastic. I dropped mine onto grass whilst removing it from my scope and it shattered into 3 pieces. I guess the large size of mine made it more prone to this.
Sorry to hear your Bahtinov focus mask is broken. It is possible for a large mask to break but normally only when dropped onto a hard surface. Not grass. Nevertheless, if you return the parts with a copy of your receipt we'll gladly replace it.
A must-have for any telescope!

What is the point of imaging for hours and hours if the focus isn't perfect? This simple mask does exactly what it says it does and performs excellently. Within a minute, you will achieve perfect focus without any overly-complicated equipment like robotic focusers. It is also very sturdy so it does not snap easily. I used one for my first imaging telescope, the Skywatcher Explorer 150PDS. Now I have two more for my two new telescopes. I would not go without one for each telescope!
great low cost improvement

After reading several reviews of the mask i decided to try one out.
For all of you who constantly re-focus to get that perfect view, this is a must! perfect focus first time. As FLO says, full credit to the inventor and FLO for a super fast delivery

Why 4 stars, because I knocked mine of the end of the scope and it hit the ground many of the parts are now broken, it is very brittle. With a bit of tape it still works great but a less brittle plastic would be better. In terms of doing its job its brilliant and makes focusing easy.
