Thank you. I will give it a shot with a manual check of distance from the lens to the sensor. Hopefully making it further away will get it crisp. I dont know how these telescope makers justify these crazy prices for what is essentially an empty pipe.

<p>I have a Celestron 5se + canon 650d. They are mated with the celestron t-ring and the 93625 t-adaptor. <a href="https://i.sstatic.net/SJdPq.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/SJdPq.jpg" alt="picture below" /></a></p>

<p>Here are some scenarios that highlight the problem:</p>

<li>look at Jupiter with camera and no eyepiece inside the t-adaptor, in telescope: clear and focused image but small.</li>

</ol>
<p>I dont know how to solve this.</p>

Here are some scenarios that highlight the problem:

2. look at Jupiter with 6mm eyepiece in telescope: clear and focused zoomed image
3. look at Jupiter with camera and no eyepiece inside the t-adaptor, in telescope: clear and focused image but small.
4. look at Jupiter with camera and 6mm eyepiece inside the t-adaptor, in telescope: large unfocused ball

I dont know how to solve this.

Using the eyepiece, and no camera lens, is a very different configuration to the camera+tube+scope (case 3). The configuration you're after is "Eyepiece projection".

I don't know exactly what you have available, but I believe you will need to fit a T-threaded extension tube to the external thread on your T-adapter. Then fit the camera onto that.

Note - before you go out and buy a new extension you can probably do a hand-held test of this by the following:

* Attach the adapter to the scope, with a low-power eyepiece in the adapter (low power makes the test easier to see.)
* Point the scope at anything distant (you can do this in daylight, but NOT at the sun of course!)
* Now hold the camera, by hand, a few inches behind the
  eyepiece+adapter. Perhaps you can use a cardboard tube to keep the stray light out.
* See if you can adjust the scope's focus, and the camera position, to get a sharp image.

If this worked, then you can get a T-threaded extension tube to go on the back of your current adapter, to hold the camera in position.
