Apogee AI-FW50 Series Filter Wheels for Alta and Ascent Models
The AI-FW50 series of filter wheels provide large format filtering solutions
for the Alta and Ascent series of imaging systems. The FW50 filter wheel
currently has two interchangeable filter carousels; A large 7 position 50mm
square wheel ideal for the U9000 and U16 imaging systems, and a 9 position
50mm round wheel ideal for any other Alta or Ascent system.
The filter wheel is controlled via USB 2.0. The filter wheel easily adapts
to the Alta D2, D7, and D9 bodies, as well as to AP systems.

NEW -
Apogee AI-AFW30-7R Series Filter Wheels for Ascent Models -
Available July 2007
The AI-AFW30-7R filter wheel provides a precision photometric
filtering solution for many of the Ascent series of imaging systems.
The wheel plugs directly into the front of the Ascent camera, using
the integrated Ascent Peripheral Interface for power and control. A
2-inch slip fit adapter is available for mounting on telescopes.
Coupled with the optional Nikon F-mount lens adapter, the camera and
filter wheel can be easily mounted to any F-mount lens, or to any
microscope with an Nikon F-mount camera adapter. The AI-AFW30-7R
filter wheel was specifically designed as a photometric wheel for
advanced astronomy applications. The AI-AFW30-7R filter wheel is not
compatible with the larger Ascent systems, such as the A9, A8300,
A105, A11000, and A16000. For those requiring larger filters for
photometric filter applications, the Optec IFW or Apogee FW50 filter
wheels are recommended. Apogee also offers the Astrodon filter sets
for this wheel, or the customer can specify alternatives.

Apogee
AI-AFW25-4R Series Filter Wheels for Ascent Models
The
AI-AFW25-4R filter wheel provides a fast compact filtering solution
for many of the Ascent series of imaging systems. The wheel plugs
directly into the front of the Ascent camera, using the integrated
Ascent Peripheral Interface for power and control. A 2-inch slip fit
adapter is available for mounting on telescopes. Coupled with the
optional Nikon F-mount lens adapter, the camera and filter wheel can
be easily mounted to any F-mount lens, or to any microscope with an
Nikon F-mount camera adapter. The AI-AFW25-4R filter wheel was
specifially designed as an entry level visual RGB or CMY wheel for
astronomy, and with faster transition time between filters for
faster image acquisition and for microscopy applications. The
AI-AFW25-4R filter wheel is not compatible with the larger Ascent
systems, such as the A9, A8300, A105, A11000, and A16000. For those
requiring larger filters or photometric filter applications, the
Optec IFW or Apogee FW50 filter wheels are recommended. For
photometric applications with smaller Ascent CCDs (less then 27mm
diag), the AI-AFW30-7R Series filter wheel is recommended. For
photometric applications with larger Ascent CCDs (more then 27mm
diag), the AI-AFW50-5R Series filter wheel is recommended.

Optec IFW Intelligent
Filter Wheel
Description
:
Optec IFW Intelligent Filter Wheel for Alta and Ascent Models
The Optec Intelligent Filter Wheel (does not include filters) brings
to astronomy a new level of sophisticated equipment for the benefit
of the astro-imager. Astro-imaging in this age of astronomy requires
the use of many color filters and the management of these filters
during an observational session can sometimes be confusing. The use
of the wrong filter could easily spoil an otherwise successful
imaging run.
The Optec
IFW has the ability to determine the identification (ID) of a
particular wheel and apply that wheel ID to a preprogrammed set of
filters. The names, not just position numbers of these filters, are
read on the eight character display and are also available to the
camera operating software via a serial interface using a simple
command structure. Up to 5 different filter wheels can have separate
IDs and each wheel can have up to 5 filters for a total of 25
identifiable filters.

Apogee LR001
Description :
Apogee LR001 - Liquid Recirculation/Chiller Unit
The LR001 Liquid Recirculation / Chiller Unit provides precise control of
the temperature of recirculated liquid for optimal cooling despite ambient
temperature fluctuations. The unit removes heat from the vicinity of the
camera, preventing atmospheric turbulence. The unit is best suited for use
with the Alta and AP cameras with optional adaptation for liquid
circulation.
As with most Apogee systems, a liquid recirculation plate has been developed
to remove heat from the camera body to reduce warm air disturbance around
the camera. Note that this option should be given careful consideration.
Application in high humidity/dew point environments are incompatible with a
chilled liquid system of this type. The typical air cooled performance is
more than adequate for most applications.

Model: Astrodon® Filters
Description :
Astrodon® tru-balance filters are the first filters designed to
match the sensitivity of modern CCD cameras. Using filters matched
with the detectors greatly simplifies all aspects of deep-sky
tri-color imaging. Benefits include shorter imaging times, G2V white
point balance, balanced OIII nebula color, and pre-balanced RGB
channels when using Kodak Blue Plus CCDs.
They are an
outgrowth of over a year and a half of research, published in Sky
and Telescope and presented at AstroImage and Imaging the Sky
conferences. The narrowband filters, H a, SII and OIII, allow you to
image when the moon is up, thereby extending the amount of imaging
time you have each month. Since they are parfocal with the LRGB
filters, you can easily focus on the L or C filter and then switch
to the narrowband filter WITHOUT refocusing.
