Astromania Telescope Camera Adapter for Astronomy Telescopes, Deluxe Tele Extender Photo Adapter Astrophotography Extended Cylinder Metal Telescope Accessories for Prime-Focus or Eyepiece-Projection

Arrived on time, in one day, and nicely wrapped and packaged. No instructions included, but the ad on Amazon has all the information that you need to get up and running. Has the look and feel of the tele-extender sold by Celestron at more than twice the price. Works perfectly for eyepiece projection astrophotography. You will need a T-piece if you intend to use it with a DSLR.

i had to pull one of the screws that holds the lens in because the end is only made for one screw, but it works :)

This extender is much better than a couple of alternative extenders in the market. The main advantage is it can be securely attached to the telescope without much work or any risk of coming loose.

Dont buy i just finished spending 3 hours trying to get this peice to work. It says in the discription that it will fit over the visual back and you van screw in the set screw to prevent movement. However it will not fit over the visual backs of either of my telescopes. Also i cannot use any eyepeices with this because of this issue. I can remove the visual back and put it into the telescope like an eyepeice, but no magnification is achieved. This is completly useless.

Perhaps I’m doing something wrong or expecting more but I cannot get this to fit properly or establish focus on my Celestron Nexstar 8se. Product does not come with useful instructions.

i do not recommend this product.1. i do not trust the connection to the dslr, just a slight tug on the camera and it will come off of the tele-extender.2. attempted to focus on the moon, saturn and jupiter with a variety of lenses, zero success.i will try again later but for now, i am disappointed. was very excited to use the lenses to photograph the moon up close.

Not Work with celestron nexstar 127slt and canon eos
