attached to a 900mm telescope with a 90D nikon camera. Easy to use.

Here are the specs you need to know before you buy. I purchased both this item from Bushnell and the Konus Double Photo Adapter Mfg. # 1070 to try to fit them to the rear focal point of my Konus Motormax 90 Maksutov telescope. (I will post these specs along with my review of that telescope since it has been a nightmare to find the correct attachment for the Konus Motormax 90). This may also apply to the Meade ETX 90 and the older Celestron C90 as the optical tubes may all be made by the same factory.First the problem: The Konus Motormax 90 has a 34mm male threaded port at the rear. Either the Bushnell or the Konus photo adapter will slide into the 45 degree diagonal finder no problem. But this adds instability and inferior glass elements to the optical path. The goal is a threaded adapter for an open extension tube. And so begins the quest...For this review let me simply state the differences between the Bushnell and Konus photo adapters and refer the reader to my review of the Konus scope for information relating to that product as well as a review of the three brands of T-Adapters available from B&H.Both adapters are 95 mm in total length.Both adapters have a 31.5 mm diameter narrow end which slides into 1.25" eyepiece holders.Both have 42 mm male threads on the long barrel to mate your camera specific T-Adapter.Both have a set screw mid way along the body, I do not know the function.Regarding the build: The Bushnell is more finely machined, the thick section is anodized and the short section is a stainless steel tube. The Konus is poorly built and poorly coated. Black stains in the shipping box indicate it may be spray painted! Not what I want attached in front of my DSLR sensor chip in Live Mode with the potential for a paint flake entering the camera body!!Here is the main difference- the short barrel.The Bushnell short steel barrel is 35 mm long, with 30 mm female threads on one end and corresponding male threads on the opposite end which screw into the long barrel. So if your scope has 30 mm male threads you want this adapter so you can screw either the long, the short or the combined barrels to your scope.The advantage of the Konus adapter is that the short nose piece can be separated from the longer barrel to alter the optical path length to achieve better focus. One can use either the short barrel or both together for slipping the adapter into an eye piece holder. The short nose can be threaded directly into a T-Adapter with 42 mm female threads. [...] the B&H webpage does not accurately reflect the Bushnell adapter I received because the shorter barrel is a separate steel piece which threads into an adapter ring. This is probably glued in place because I cannot unthread this adapter ring. If I could then I would keep the Bushnell adapter. But as it stands now I am unable to attach the short barrel of the Bushnell directly to a T-Adapter. I can see that the adapter ring has 42 mm male threads, if only I could remove it then I would have a very useful item. Good for stability, but no option of shortening optical path.In either case I do not trust a set screw to hold my expensive DSLR in place (which is why I am planning to purchase a dedicated astrophotography CCD). I am still seeking a solution to directly mount an extension tube to my telescope, and the Bushnell has more options since it has internal female threads on the short barrel, and a more solid build. Hope this helps.

I bought this to get a start on astophotography with a Celestron 4.5" 48" reflector and a Canon T1i. I'm chiming in to add to the other comments: The bottom end of the eyepiece-holder is a T-mount thread and can be screwed into your camera's T-ring (sold separately! ;-) ) to position your camera for 'prime focus' use-- i.e. with no telescope eyepiece-- if your scope's focus rack will allow your sensor to get close enough.

Adapter to change the focal plane for astrophotography with a SLR or Digital Camera.

Simple device easy to use. Good price/quality relation.

The fitting to the telescope was wonderful and fit like a glove to my Bushnell reflecting telescope. The big problem was that this adatping mount placed my Canon Digital Rebel 1/4 inch too far from the focal point even when I had the focus adjuster at minimum. I was about to shrug my shoulders and chalk it up as a loss but I decided to unscrew the silver lower cyliner and grind off the 1/4 inch I needed and then put it together again. Now it works fine and I look forward to photographing the stars. It's an okay buy but it may need some major "adjusting" depending on the telescope you have.
