Product Overview
The Starfield
Newtonian series F/4 Reflector
telescopes are designed with quality in mind.
Optical Performance
The Primary mirror is made of BK7 optical glass which is
known for its thermal stability. The coated
mirror is not only dielectrically coated, but also it has a protective layer of
SiO2 (quartz) for durability. Mounted in a cell with six easy to use collimation
knobs for easy collimation. The mirror
center is also marked which makes using a laser simple
An APS-S DSLR camera or dedicated camera such as the QHY2600
or ZWO ASI2600MC-Pro, both with APS-C sensors, you will achieve a near 2
degrees field of view diagonally. Large objects
like Andromeda and the Orion Nebula will fit in nicely.
Features
The monorail focuser with 10:1 2 speed control comes
standard. Providing enough lifting power
for a DSLR or CMOS deep sky camera. A
motor can be added for even great automated control!
Split Tube rings with felt, to not markup the OTA tube
finish, come with a vixen style dovetail with adjustment screws. It is also easy to add accessories or another
dovetail to the top of the OTA with the provided M6 screw holes located on the top
of the rings.
The inside of the OTA has a matte black interior finish to
reduce stray reflection and increase image contrast. The overall length of the OTA extends past the
focuser, to also prevent stay light from entering the telescope and increase overall
contrast.
The primary mirror cell also includes a low noise,
long-lifetime cooling fan powered by 8 AA batteries (batteries not included).
An 8x50mm finder scope, and extension tube is included as
well for visual use.
