Product Info

Manufacturer Description

Farpoint Bahtinov focus mask for astrophotography - for standard Celestron 9.25" SCTs (not for use with Fastar capable SCT which has a larger secondary). Manufacturer part number FP415.

Farpoint Bahtinov Masks are by far, the easiest, fastest and most consistent manual focusing aid available to the amateur astrophotographer. In 2008, Pavel Bahtinov, a Russian amateur telescope maker and astronomer, published an ingenious new way to easily focus your DSLR camera, webcam or CCD camera for astrophotography. The method is simple, very intuitive, and the device has universally been named after the inventor: The Bahtinov Mask.

Prior to the innovative design of the Bahtinov Mask, astrophotographers could spend ten minutes or more just obtaining a reasonable focus. Problems with seeing, exposure length, and camera noise all increased the difficulty of and time spent finding perfect focus. With the Farpoint Bahtinov Mask, the process of finding the perfect focus whether it be through a DSLR, CCD or a WebCam takes a matter of seconds because the process is unaffected by seeing, noise and allows short exposure lengths!

Simply place a magnitude 4 or brighter star in the field of view of your camera, place the Farpoint Bahtinov Mask over your telescope’s objective and focusing becomes as simple as centering an easy to see diffraction spike!

Farpoint manufactures this "lifesaving" astrophotography tool out of virtually indestructible ABS plastic, which comes in two major types (for refractors and SCTs) and in a range of sizes. The Farpoint Bahtinov Mask will ensure that you spend more time imaging and less time focusing for years to come! Whether you focus manually or electronically, the Farpoint Bahtinov Mask is an essential tool for any astrophotographer.

      Cons:

      Comments:

      After years of astrophotography, I got around to use one of these instead of using software to focus, and the results have been way cooler than I excepted.

      5.0 Batinov Disc for a Celestron NexStar 8SE telescope

      Pros:

      Cons:

      Comments:

      As soon as it arrived I was able to place it on the front of the telescope and begin to focus it. Focusing is very easy and if you line up the third line in the middle it is next to perfect.

      5.0 10" Schmidt Cassegrain Bahtinov Mask

      Pros:

      Cons:

      Comments:

      I had purchased a bahtinov mask for my 120 mm refractor, and it works GREAT. So well, in fact, that I decided to purchase the 10" mask for my SCT. I received the product in two days, tried it out, and it works GREAT on the SCT, too. Accurate focusing has NEVER been so easy.

      The mask fits well my 115mm scope. I have three FP masks for my three scopes--they are cheap and effective, and have survived some mishandling by me.

      Pros:

      Cons:

      Comments:

      Although I have not used this mask for focusing just yet, I have a larger version for my C8 that I have been using f or a few years. It is an excellent way to achieve fine focus on bright stars prior to imaging with my telescope and camera. As always, Agena is first rate at ordering and delivery.

      5.0 Indispensable

      Pros:

      Cons:

      Comments:

      Indispensable in knowing the proper focus when imaging deep sky objects. Think about it. Brighter stars look like larger blobs on a computer monitor. You want the finest resolution and this mask will take the uncertainty out of what’s the best focus at that moment. I wouldn’t use it on planetary objects, however I suppose it’s possible.

      This item just works like it is supposed to. Care must be taken to avoid touching the corrector plate when placing or removing it from the telescope. I used it with a DSLR camera and had to use the focus magnifier to see the spikes.

      5.0 Eliminates Guesswork

      Pros:

      Easy to Use,Lightweight,Accurate,Strong Construction

      Cons:

      Comments:

      Bahtinov focus masks make achieving accurate focus objectively instead of guessing and hoping for the best. The diffraction spikes it creates are used to determine focus. It still requires a somewhat critical eye and a few iterations to get it right. Once it's set, lock the focuser and it might be good for the rest of the evening; however, I found it necessary to refocus later in the session (probably scope/lens and temperature dependent).

      Easy to use, durable, good quality. I recommend it highly.

      3.0 Does The Job but May Block Too Much Light

      Pros:

      Lightweight,Easy to Use

      Cons:

      Blocks A Lot Of Light

      Comments:

      Bought this to take my planetary work to 11 and it does help focus but I wonder if I should have made myself a "Y" focus mask which works the same way and would let more light through. I've made one before and it does work.

      5.0 The best example of this type of product

      Pros:

      Strong Construction,Accurate,Easy to Use

      Cons:

      Comments:

      I purchased two of these Bahtinov masks - one for my 8" Meade SCT, and the smallest adjustable one for my 200mm telephoto lens.
      These things work perfectly! There's lots of webpages telling you how to make one, but after a struggle to find the right material, and researching alternate ways to make these (3D printing, etc.), I think it's way easier to buy these:
      The material is thick, which means that not only is it durable, but it is easy to remove from the front of my scope once I'm all focused in, without risking smearing the objective with my fingers.
      The edges are sharp and precise (exactly the problem I worried about when considering making one of these), so the diffraction pattern shows up precisely as it should.
      The SCT model (with the hole in the middle for the secondary) fits perfectly. The adjustable model is easy to work with - the three pegs, or bolts, or whatever, are actually threaded capscrews, but they don't come with plastic nuts; they are simply inserted into the rubber grommets that hold them in place against the end of the lens (or lens hood, in my case). At first glance, it doesn't look all that secure, but it actually works just fine. The diffraction pattern does not need to be perfectly centered in the lens to work properly, so the adjustment capability is more than adequate for the task.
      These masks have advanced by leaps and bounds the results of my rudimentary astrophotography efforts, both "prime-focus" through my SCT, and with my DSLR piggy-backed on the scope. I couldn't be happier with these!

      5.0 Great focusing tool for photography

      Pros:

      Lightweight,Easy to Use,Accurate

      Cons:

      Comments:

      I have had difficulty focusing the camera on my telescope. It is vital to get sharp images.
      Using this device you can get accurate focus and it takes about 30 seconds.
      I found best to use a bright star (Sirius in southern hemisphere) and focus the telescope to the camera. Don't change focus after that. Using some adjustment in extension tube you can focus the eyepiece to this.
      Using a planet is too bright and big and doesn't work well. Focus on the star then move to the Planet.

      3.0 Good focusing tool but not perfect

      Pros:

      Easy to Use,Lightweight

      Cons:

      Comments:

      The mask can assist the astronomer in achieving very close focus but in my experience, using your camera for final focus is absolutely required in order to achieve critical focus. FWHM measurement using a focusing routine in your camera acquisition software will get you the remainder of the way to critical focus. So in my opinion, this mask can serve as a step in achieving focus but not the final step. The mask is adjustable so it can be adjusted to fit your scopes dew shield. Very lightweight and portable.

      Does exactly what advertised, easy to adjust between my different scopes.

      It would be nice if it came with its own case or something to hold it in, considering the format of this thing (wide flat mask with 3 longish screws sticking out of it) I found is a non trivial exersize putting it in my accessories box

      To achieve critical focus for astrophotography. The mask is adjustable and is easily mounted to the dewshield on my Celestron 9.25" SCT. What's else is there to say - Pavel Bahtinov got it right. This mask is made of ABS so a little bendy, but for the price it is a great product and with care it shouls last you a long time.

      This is a helpful tool to reach accurate focus. Bahtinov was a smart guy. The attachment to the scope (dew shield) with the four bolts that don't screw into anything is amateurish at best. Any light breeze blows the mask off the scope. (I have the version for the 5.5-8.5" OD.)

      This may be the best and most useful piece of equipment if you're wanting to do astrophotography. Focusing accuracy can now be measured instead of estimated. In two minutes I can achieve pinpoint stars, instead of spending 10-15 fine tuning and trying to compare test shots.

      Compact,Lightweight,Strong Construction,Easy to Use,Accurate

      Cons:

      Comments:

      Focusing a telescope on faint stars, nebulae, or galaxies is more often an art than a science. It's incredibly hard to judge whether your scope is perfectly focused or just mostly focused.

      With a Bahtinov Mask, there's now a quick and easy way to measure your focus. The first time I used it was last night, and I achieved perfect focus in under 5 minutes. In the past it might have taken me ten or fifteen long exposures on a faint object to determine that I was where I needed to be. Now that time is spent imaging or observing, not focusing.

      The instructions are easy to follow and the results are spectacular.

      This has cut my focusing time by 75%. I get a good focus with the mask, then go to the Fine Focus program in Nebulosity and try to get a better focus. The mask puts you so close, so quickly, that I don't really have to fine tune with Nebulosity. But I do, always trying to get the perfect focus. A real time saver!!!!!

      Cons:

      Comments:

      I will have to say that this product made focusing easy for me. The mechanism that holds the mast to the telescope lacks a bit but I had to purchase a generic mask so that is to be expected a bit. I certinally recomend this product because it will take the guess-work out of getting perfect focus.
