3. What Camera Settings Should I Use for Shooting Through a Telescope?
Determining the correct camera settings for telescope photography is essential for capturing optimal images. The aperture is determined by the telescope, while shutter speed and ISO need adjustments based on lighting conditions.
Start with a shutter speed of 1/250th of a second to freeze the moon’s motion and maintain sharp detail. Slowing the shutter to 1/100th or even 1/80th of a second can work, depending on the telescope’s stability and the moon’s position. Regardless of the telescope, be prepared to shoot at a high ISO, often around 3200 or even 8000, to achieve a good exposure. By understanding these settings, you can capture stunning images of celestial objects, planets, and deep-sky phenomena.
4. What Are Some Examples of Telescope Moon Photos?
Capturing stunning images of the moon through a telescope requires the right settings and equipment. Professional astrophotographer Steve Brazill has provided two excellent examples of his work, along with the settings he used to achieve these results.
4.1. Photo 1
Detailed moon shot with variable projection adapter at 1900mm, f/15, 1/100, ISO 6400
- Focal Length: 1900mm (plus magnification from the variable projection camera adapter)
- Aperture: f/15 (telescope’s aperture)
- Shutter Speed: 1/100 second
- ISO: 6400
Steve created this photo using the variable projection camera adapter, which added some magnification to the telescope’s 1900mm focal length. He slowed the shutter speed to 1/100 to compensate for the f/15 aperture and keep the ISO as low as possible.
4.2. Photo 2
Enhanced magnification moon photo at 1900mm, f/15, 1/100, ISO 8000
- Focal Length: 1900mm (plus additional magnification from the eyepiece and adapter)
- Aperture: f/15
- Shutter Speed: 1/100 second
- ISO: 8000
This shot was taken with an eyepiece added to the variable projection camera adapter, further increasing the magnification. Notice the shallow depth of field on the left side of the frame, a common issue when shooting with high magnification.
5. What is Image Stacking in Astrophotography?
Image stacking is a technique where multiple photos with the same settings are combined to extrapolate more detail than a single image could capture.

Using software, data from numerous photos is used to create a significantly more detailed final image. For example, 169 frames were stacked to produce a sharp image of the moon using a 20-year-old Quantaray 70-300 f/4-5.6 lens on a Canon 80D. This method differs from focus stacking or exposure stacking, where images with different focus points or exposures are blended.
6. Who Are Some Inspiring Astrophotographers?
Andrew McCarthy is an inspiring astrophotographer who uses advanced techniques to capture stunning images of the moon.
