PHOTOGRAPHY WITH NEXSTAR SE
After looking at the night sky for a while, you may want to try photographing it In addition to the specific accessories required
for celestial photography, there is the need for a camera—but not just any camera The camera does not have to have many of
the features offered on today's state-of-the-art equipment For example, you don't need auto focus capability or mirror lock up
Here are the mandatory features a camera needs for celestial photography First, a "B" setting that allows for time exposures
This excludes point-and-shoot cameras and limits the selection to DSLR cameras, the most common type of camera on the
market today
Second, the "B" or manual setting should NOT run off the battery Many new electronic cameras use the battery to keep the
shutter open during time exposures Once the batteries are drained, usually after a few minutes, the shutter closes, whether you
were finished with the exposure or not Look for a camera that has a manual shutter when operating in the time exposure mode
Olympus, Nikon, Minolta, Pentax, Canon and others have made such camera bodies
The camera must have interchangeable lenses so you can attach it to the telescope and so you can use a variety of lenses for
piggyback photography If you can't find a new camera, you can purchase a used camera body that is not 100-percent
functional The light meter, for example, does not have to be operational since you will be determining the exposure
length manually
You also need a cable release with a locking function to hold the shutter open while you do other things Mechanical and air
release models are available
ATTACHING A CAMERA TO THE NEXSTAR SE
Attaching a DSLR camera to the NexStar requires the use of the optional T-adapter (#93633-A) and a T-ring specific to the
brand of camera being used See Celestron com for choices To attach the photographic accessories:
1 Remove the visual back from the rear cell
2 Thread the T-adapter securely onto the rear cell of the telescope
3 Thread the T-ring onto the exposed end of the T-adapter
4 Remove any lens from the body of your camera
5 Attach the camera body to the T-ring by aligning the dot on the
side of the T-ring with the dot on the camera body and twisting
6 Adjust the slew limits to prevent these accessories from hitting
the fork arm or base during operation
NOTE: Smartphone cameras can easily be attached to a NexStar
telescope using the NexYZ 3-Axis Smartphone Adapter.
