Does the 1.25 adpater unscrew so I can use this for both projection and prime focus (female T2 thread)? Basically is this two pieces? thanks

I don't really understand your question... This adapter is in two pieces. There's the T2 threaded bit on one end of the ~2" tube, and the other end of the 2" tube has female T2 threads on it and the 1.25" tube has a shoulder with a T2 threaded part that screws into that. So, you could put a T-Thread adapter on the end of the 2" tube, or, you could put it right onto the 1.25" part. (It hadn't occurred to me to do that until I saw your question, but I just tested it.)

the adapter has a 1/4 male, so it goes into a 1/4 female, it also accepts a 3.5 female, so your device has to have a 3.5 male. Not to be gross, but think about the anatomy. A male sticks out, and a female takes the point inside. Sorry, but that is the way I remember. Sometimes it is difficult to ascertain because the portion that sticks out is inside something, but this is pretty straight forward. I hope this helps!

Close, but not the same. The T/T2 mount is threaded 42mm diameter X .75mm pitch. M42 is 42mm diameter X 1mm pitch threads. This link may help: http://en.wikipedia.org/wiki/T-mount There are adapters to use M42 threaded lenses on Canon EOS cameras (google "M42 to EOS adapter"), if that is what you are looking for, but things like focusing will have to be done manually. I bought the Fotodiox T/T2 adapter to mount my EOS camera to an Orion universal camera to telescope adapter, and it works for that use. After receiving your email reply, yes it will work to count 10 threads and measure to determine what pitch you need, 1mm or .75mm. I also have a threaded 1.25" diameter tube that screws into my Fotodiox T/T2 to turn it into a standard telescope "T" mount. Both the T mount tube and the Orion adapter only have about 6 threads, so 10 are not available to make things easy!

Hi Kayla,I try to share my experience if it can help you. I bought this adapter few months back so I can use my Spny alpha lenses on my Nikon F mount. It seems you Need to open up on the adapter to allow more light into the sensor. Notice the 7 white dots on the adapter? Try to turn to the darkest dot. However it seems to allow some light leak into the picture and it is not easy to turn it to the dot and stay there. Seems the barrel moves back to white dot so I use slow tap to keep it in place. Rather sloppy.What do you mean by horrible? Do you mean the image looks darker? I hope it helps. Hi Kayla,I try to share my experience if it can help you.

Not normal from what I can tell. It shouldn't unscrew, it should change focus from blurry to clear to blurry.

Yes, it is a clamp on additional bracket. One removes the insignia cover on the hinge between the two objective lenses and uses the threaded bolt that comes with the bracket to attach it. The right angle configuration of the bracket works just fine with a unipod, which is how I used it to watch rowing races.

This ring has male threads on both sides. It enables you to put two lenses together for macro-photography. Normally you would use a small prime lens mounted in reverse in front of a longer lens, such as a 50mm lens in front with a perhaps 100mm lens(or a zoom) mounted on the camera in the normal way. Your brand of camera is irrelevant as the ring screws into the lens and is not attached directly to the camera. You are then using the prime lens mounted in reverse as a substitute for a closeup filter. Generally people use this setup to get magnifications higher than 1:1. You can use this ring in conjunction with a step-up ring if necessary to adjust to your particular pair of lenses.

This Focal Reducer will screw in where the back is. You unscrew the back, screw this on, then screw the back back on. Also, this is really designed for Astrophotography. It will work for visual use, but most people get this for AP.

i took the macro lens off and the 58mm want fit, it seems the threads are different

Unfortunately, I returned the item due to the fact that it only had one adjustment screw. Instead of the two shown in this advertisement. Hope this helps somewhat.........

There are three axial screws keeping silver ring in place. In distance numbers are facing in wrong direction you can unscrew silver ring and ajust it. I did it. If you place spacer bush between silver ring and black body you can ajust infinity focus (if your lens with adapter focus before infinity). This trick I didn't try.

Screw in center needs to be tight...no wobbly...and the rotation quit on mine after a short time (couple weeks of 24/7)...a little light lube might get it going again...I suggest 3-in-one oil...sewing machine oil...don't get it on the lens or it will crap it out...I used P-B Blaster and it wasted my lens...but it quit spinning again very shortly ,so that was a moot point...hthy...Hobbiehubbcapp.

sorry can't answer specifically. I understand the question. The descripton sucks. The female side is the thread standard for R12 systems as far as I understand. The male side are the standard threads for a R134A system. For example the vacuum pump I borrowed was an older model and sold before R134A became standardized. I recently purchased a manifold gage set and the set has fittings for R134A. I think the R134A thread is an ACME thread standard but not positive. I had to use this as an adapter so I could hook up my manifold gage vacuum line to the vacuum pump. Hope this might help you out. sorry can't answer specifically. I understand the question.

This replaces your 1.25" eyepiece. It can still be used with a Barlow lens or focal reducer.

The adapter does allow you to use the full function of the Canon lenses. The mount was some what loose and could possibly loose contact with the pins. This is annoying and was the reason I returned the item. I heard that some people received a better fitting adapter that did not have the play I experienced. The Canon version does not have this issue. Quite a price difference but I really like the Canon one better because of the fit issue.

It is a standard 1.25 inch EP. As noted in the other answers it may not be possible to focus correctly. The EP on the Regal scope works in my Lunt Solar telescope and the Lunt works in the Regal. In general though you will have to test it out. The scope is very nice. My first one had a problem with the focuser after 90 day replacement warranty ran out. Celestron took it back but it was about 2 months before I got a replacement. When it was working it was a very nice scope, and I like the replacement although I use my other scopes more.

My equipment has the standard 1/4 inch thread and these will not screw onto the camera or bino's. I couldn't find details on thread size when these were purchased. I think the threads are metric. Trying to find a camera shop to swap out the screws.
