Variable Projection Camera Adapter 1.25 Inch Extension Tube Kit

So far this works perfectly as advertised. It securly holds the eyepiece and the camera in place. It feels heavy duty, which is great. Do be prepared for the added weight in the back, but you'll find it to be a high quality product! There are no glare or reflections. It gives you the ability to use a larger sensor and regain some focal length, like with a barlow, at a much cheaper cost!

I have to say, at the beginning I was disappointed. I received the item with only one of the two fixation screws, and it arrived broken. However, the seller contacted me and sent the missing screws. The product works excellently, and the seller's service was very, very good. Fully recommended.

The adapter looks great, the machine shop and paint looks solid and even, so the workmanship is great. The threads are also matching all my scope and my other adapters. The only problem is, it doesn't work for my setting of a celestron 130mm f/5 reflector and a canon t5i. my canon just can't focus with the included pieces. (I have a celestron T-ring already) Until I put a lens from my 2x Barlow onto the prime-focus adapter, I finally was able to get a focus. Then I stopped testing the setup. I don't know whom should I complaint to, but this should be in some sort of information board so people can check that and understand how to do, otherwise, it'll be just a lot of frustration for some people.

Normally, attaching a camera to a telescope gives you only one set magnification, typically for viewing the moon or sun. This camera adapter allows a camera to zoom into smaller stars or planets depending on the focal length of the eyepiece. The adapter can zoom by simply extending the adapter so that eyepiece changing is kept to a minimum. The adapter is made of very sturdy metal and is solid when connected to the telescope. Note that most eyepieces above 30 mm won't fit in the adapter due to their large size.

I can near focus with my Z50, but no distance more than a quarter mile. That is even after fiddling with it a lot. I couldn't turn the focuser in enough. Cut the outer tube down 1/2 inch and almost had it focusing. I think I think it would have worked if I could have removed the plug in the inner tube so the eyepiece could be lower. No dice, it is extremely well attached. Oh well. Telescope is a Sky Watcher 150p Heritage. It is another part to cannibalize.

It’s a great tool for anyone getting into astrophotography. The nose piece that comes with it is useful by itself, and the adjustable eye piece holders are great for using any 1.25’’ eyepiece with a telescope and camera. It’s made out of solid metal which means it’s very robust, but it could be a downside for astrophotographers using EQ mounts that are trying to keep the weight down as much as possible, as it is actually a bit heavy. Would recommend.

I've had no problems. I have only loaded it with a DSLR, and the attachments appear sufficiently rigid. I have not evaluated whether ther might be some flexure, but I expect the 1 1/4 in focusing tube would be the weak point.

This is a very nicely made device with a lot of flexibility for either prime focus or eyepiece projection astrophotography. The pieces fit nicely together and I especially like the sliding tube to adjust the camera to eyepiece distance. I am using it with a Sony E T-Ring and a6300 camera on a Televue 85. I did find that for eyepiece projection there was not enough focus range to use it with a 2" diagonal and 1.25" adapter (my usual configuration for this telescope) or directly into the telescope focusser. However, using a 1.25" diagonal resulted in placing the eyepiece and camera at a position that allows it reach focus.

very good

it came in a good shape, good packaging. i bought this thinking i’d know how to use it or at least i’d know how to read the instructions (there’s no instructions with it.) but silly me for thinking that lmao. i did the same things that are shown on the pictures but i still didn’t figure it out. i have a Canon camera and a Celestron telescope, everything was good but then i didn’t know why my camera wasn’t showing anything as if i didn’t have a lens on it in the first place (i did install my own eyepiece) i had it for a couple months now but i still dont know how to use it lmao although good metal! i’m not regretting buying because i know someday i’ll know what kind of stupid step i missed for it not to work and laugh about it.

I use it with my dobsonian telescope. Easy to use and setup was a breeze.

Product seems well made and should last for years

I like the product because I got what I asked for.
