Some tips for better digital photos:
•
If you cannot remove the lens to your camera, look for a commercially available digital
T-adapter. New solutions for attaching a digital camera to a telescope are becoming
available as time goes by.
•
If the camera is not directly coupled to the eyepiece, keep it as close to the eyepiece as
possible and center the image to be photographed to minimize vignetting (darkening of the
edges of the photo).
•
Try to block ambient light (from street lights, house, etc.) from the eyepiece and the
camera with a piece of cardboard, a screen, etc.
•
Keep extra (charged) batteries on hand for your camera as digital cameras often drain
batteries in a short period of time. Rechargeable Lithium batteries provide power for a
longer period than non-rechargeable batteries. If practical, use an AC adapter.
•
Avoid short-focus eyepieces. They present many difficulties for digital cameras.
•
If using manual focus, set to infinity. Otherwise, using the camera’s autofocus is OK.
•
Experiment with your camera’s exposure, brightness and /or contrast settings. Keep notes
for future reference.
•
Clean eyepieces and camera lens as needed.
•
Many digital cameras have a manual ISO setting. Short exposures times work the best.
•
Use your camera’s highest image quality and lowest compression settings. Although this
fills up your camera’s memory more quickly, it produces the best quality photos.
•
Use the camera’s timer or remote shutter release (if available for your camera) to minimize
vibration. Wireless shutter releases may be available for some model digital cameras. If you
do not have a shutter release, use the camera’s timer (sometimes called “self-timer”), which
is available with most digital cameras. The timer may also help minimize vibration.
Photography with Meade’s AutoStar Suite™
The AutoStar Suite with Meade LPI™ (Lunar Planetary Imager) or Meade’s line of Deep Sky
Imager™ turns your Meade LX90 telescope, AutoStar and PC into even more powerful and
easy-to-use astronomical instrument.
LPI (

) and Deep Sky Imager (
Fig. 16
) combine the power of an electronic
astronomical imager with the simplicity of a web cam. Check out the following imager features:
• Achieves great results the first time out on the Moon, planets, deep-sky objects and terrestrial
targets.
• Easy to use with real-time display of object on your PC screen. Just center, focus and shoot.
• Magic Eye software-assisted focusing.
• Automatic and manual exposure control from .001 seconds to one hour.
• Automatically takes multiple exposures.
AutoStar Suite Software includes powerful tools to help you get the most from your Meade LX90
telescope:
• Sophisticated planetarium program with over 19 million objects.
• Select objects from the planetarium display and the telescope slews to those objects.
• Create time-lapse movies of objects, such as Jupiter
• Create your own Guided Tours.
• Advanced Image Processing Software includes Unsharp Masking, Convolution Filtering and
many other features.
• Controls all AutoStar functions from your PC.
• Talking Telescope software translates AutoStar text to synthesized speech through PC
speaker.
• Includes a cable to connect your LX90 model to your PC.
