Custom Filters –
50mm LRGBC, UBVRI and narrow band filters are available. SBIG’s LRGBC
filter set contains both a Luminance and a Clear filter in addition to the RGB filters. The
Luminance filter is both UV and IR blocked. The clear filter is not blocked. The RGB
passbands have been specifically designed for use with the CCDs used in the Research Series
cameras. All filters in the set are AR coated. Our photometric UBVRI filters are also AR
coated.
12V Water Pump –
A submersible pump is available for water cooling. It is only necessary to
provide a constant flow of water through the heat exchanger to achieve maximum cooling.
Cooling the water supply is not necessary or advised. If you do not have a ready source of
water this pump will work in the field from 12VDC.
Extra Filter Carousel –
If you have more than one set of filters that you change often, it might
be easier to keep more than one carousel handy, each with its own set of filters. Then,
changing the set requires only swapping the filter carousel.
Nikon Lens Adapter –
This adapter allows the use of Nikon 35mm camera lenses on Research
Series cameras for wide field imaging.
Relay Adapter Box –
The camera’s internal relays used for self-guiding are electronic (TTL)
type relays. These work with the vast majority of telescope drive systems today. However,
some telescopes, particularly older models, may require mechanical relays to isolate the
telescope from the camera. The mechanical relays also provide both normally open and
normally closed contacts for custom applications.
12VDC power cord with cigarette lighter adapter –
A 12VDC power cord is available for field
operation directly from a battery.
1.1.3. Parts and Assembly
To help you get familiar with the camera and its various
parts please refer to the following diagrams and pictures.
The large central portion of the camera body contains the
CCD chamber, electronics, desiccant plug, shutter, heat
exchanger, fan and a power supply allowing 12VDC
operation in the field. A separate AC to 12VDC desktop
adapter is also provided. The front cover contains the
internal filter wheel. A self-aligning connector allows
electric signals to pass from the main body to the filter
wheel when the front cover is attached to the main body.
This allows the user to easily remove the front cover to gain
access to the filters and desiccant plug when necessary.
The filter wheel will not operate when the front cover is
removed from the main body. The front cover also holds
the accessory mounting plate on the outside of the aperture over the CCD. The accessory plate is
