How do you focus a DSLR mounted to a telescope?
To focus a telescope with a camera attached, you simply need to turn the focuser knob until your subject comes into view. Most of the telescopes amateurs use for astrophotography (Here are the ones I recommend) will have dual-speed, 10-1 focusers, and the ability to lock the focuser in place.
Why is my aperture locked?
And because you can’t change your aperture either it seems especially like there’s a problem. But in fact, that disappearing “L” is simply your camera’s way of reminding you that the scroll wheel on the back of the camera—the big round dial that’s officially called the Quick Control Dial—is in the locked position.
How do you take DSLR pictures with a telescope?
Imaging with a DSLR through the telescope
- The principle of taking photographs through your telescope with your DSLR is quite simple: just use the telescope in place of the camera lens, and snap away.
- However, the best solution, if your camera manufacturer provides the software, is to shoot ‘tethered’ to a computer.
How do I match my camera to my telescope?
Simply enter the telescope’s focal length, the camera’s pixel size and your sky’s seeing conditions to determine if they are a good match 🙂 A few notes: We are assuming OK seeing is between 2-4” FWHM and a resolution between 0.67” and 2” per pixel is the sweet spot.
Can you use a Barlow with a DSLR?
To attach your DSLR to the Barlow T-Adapter you’ll need a brand specific Camera T-Ring, either Canon or Nikon. Unless you’re using a solar telescope, remove the diagonal and attach the Barlow T-Adapter to the visual back of the telescope.

How do I unlock my aperture?
Aperture (exposure modes A and M): Press the selected control and rotate the sub-command dial until F icons appear in the viewfinder and the control panel. To unlock aperture, press the control and rotate the sub-command dial until the F icons disappear from the displays.
Why can’t I change the aperture?
There is some dirt or something on the electronic connectors between the lens and the camera body. The lens has an Aperture Lock switch set to the ‘Locked’ position. Without knowing the camera make/model and lens make/model, it’s impossible to expand on this possibility further.
Can I use a telescope as a telephoto lens?
Instead of changing magnification by moving internal lens elements as a zoom lens does, the magnification of a telescope is changed by switching eyepieces. So technically, no, you can’t use a telescope as a zoom lens.
How do I attach my Barlow to my DSLR?
The easiest way to attach just about any barlow to a camera is to put the barlow in a 1.25″ (or 2″) eyepiece holder (or your 1.25″ visual back) just as you would for visual use and then use a 1.25″ (or 2″) eyepiece to T-thread adapter to connect between the output side of the barlow (that 1.25″ or 2″ female eyepiece …
How do you use a DSLR camera with a telescope?
Also, our method involves attaching the DSLR camera directly to the telescope, rather than pointing a camera into the eyepiece. An eyepiece or barlow lens can increase the magnification of your image, but it will also reduce the amount of light reaching the sensor and degrade image quality.
How to shoot the Moon with a DSLR camera?
You’ll need to have a lens with an aperture of f/11. When it comes to shooting the moon with your DSLR, choosing a long telephoto lens is the best way to go. A steady tripod will really help you a lot when it comes to making sure that your camera gets less movement when taking photos.
What is the best aperture for astrophotography?
A focal length ranging from 300-500mm is what’s going to work with, let’s say, shooting the moon. For your lens’ aperture, since taking great astrophotos happens when the sky is dark, the best setting would always be f/2.8 or lower.
How does digiscoping with a DSLR camera work?
When you compare camera lenses with the same focal lengths to our telescopes, you’ll find digiscoping with a DSLR to be shockingly affordable. The actual process of digiscoping with a DSLR camera involves directly fastening the camera body to an astronomical telescope using an adapter. There are two parts to this connection.
