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 ...
Two pieces in a telescope make this possible: The objective lens (in refractors) or primary mirror (in reflectors) collects lots of light from a distant object and brings that light, or image, to a point or focus. An eyepiece lens takes the bright light from the focus of the objective...

To use the mask, you simply need to cover the telescope’s objective and point the telescope at a bright star. The mask creates a pattern that allows you to fine-tune the focus of the telescope to produce the signature “central star-spike” pattern. I have been using a Bahtinov mask t...
The focuser has two dials on either side and turning these will allow you to focus the view through the eyepiece. As for theeyepiecesthemselves, your telescope most likely came with two to get you started.9The eyepieces slot into the focuser and you’ll notice there’s at least one small...
Third, watch the the video, about 20 seconds in, where the Barlow is being put in the telescope. Look at the front end of the telescope. Do you see how much it is shaking just putting the Barlow in? It's going to shake that much or more when you try to focus it. ...
If you have access to a telescope, line up on the Moon and focus accurately, keeping glasses on if you wear them. Once done, point the camera down the eyepiece and press the shutter button. It’s fiddly, but can produce impressive results. Beginner lunar photography Camer...
Conjunctions: These events happen when the moon appears close in its orbit to another celestial object, such as Venus, Mars, Jupiter or Saturn. High-resolution lunar photography: This technique uses a teleconverter or a telescope to capture a collage of images blended into a single image. Celest...
who knew I'd love to have a telescope. My 60mm Tasco taught me a lot. I had a T-mount adaptor which let me use it as a 700mm f/11 lens with my film SLRs. It worked poorly for photography because it was a $75 scope and too slow to get short enough shutter speeds with film....
or compound when you buy your first telescope, as they’re all more than up to the task at hand. However, if you’re thinking of transporting the scope to a dark location on a regular basis (for example, on a camping trip) you’ll probably find a reflector or compound to be the mo...
