Speciﬁcations

For imaging deep sky objects under light-polluted skies, you can try a SkyGlow Broadband light pollution ﬁler. This helps suppress the light emitted by street- lights, but still lets most of the light from deep sky objects through. An increase in overall image contrast results.

USB Extension Cable

In many instances, it is likely a longer cable for the SSDSI-II will be needed in order to comfortably setup telescope, camera, and computer. We recommend purchasing a 10' USB extension cable if you need more cord length (available through Orion, check the catalog and/or www.OrionTelescopes.com).

Care and Maintenance

When the SSDSI-II is not in use, the cover cap should be replaced on the end of the nosepiece. This prevents dust from accumulating on the SSDSI-II’s opti- cal window. If signiﬁcant dust does accumulate on the optical window, or the optical surface is touched, then it should be cleaned.

Any quality optical lens cleaning tissue and optical lens cleaning ﬂuid speciﬁ- cally designed for multi-coated optics can be used to clean the glass surface of the SSDSI-II’s optical window. Never use regular glass cleaner or cleaning ﬂuid designed for eyeglasses.

Before cleaning with ﬂuid and tissue, blow any loose particles off the surface with a blower bulb or compressed air. Then apply some cleaning ﬂuid to a tis- sue, never directly on the optics. Wipe the optical surface gently in a circular motion, then remove any excess ﬂuid with a fresh lens tissue. Oily ﬁngerprints and smudges may be removed using this method. Use caution; rubbing too hard may cause scratches.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device nay not cause harmful interference, and (2) this device must accept any interference received, including interfer- ence that may cause undesired operation.

Changes of modiﬁcations not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruc- tions, may cause harmful interference to radio communications. However, there is no guarantee that interference will no occur in a particular installation. If this equipment does cause harmful interference to radio or television recep- tion, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment into an output on a circuit different from that to which the receiver in connected.

Consult the dealer or an experienced radio/TV technician for help.

A shielded cable must be used when connecting a peripheral to the serial ports.
