There are a small number of manufactures producing really
nice portable reflectors with a truss tube design. Starmaster
is one of them. Several folks in my observing group have purchased them
and they are all very pleased with their performance.
The 18" version is my favorite of the product line.
Rick Singmaster, uses oak plywood for his primary components. Other
manufacturers use apple ply composed of thinner layers of laminated
veniers. Apple ply is stronger, heavier, and more expensive. For a
telescope however, it seems that standard grade oak is perfectly
acceptable. The rocker box and mirror cage are both constructed from this
material. Rick uses a light stain which complements the natural
grains of the oak. The new finish he is using is thicker and gives
the construction a fine glossy furniture appearance.
The mirror is mounted in a sturdy metal cell which can
be removed from the mirror box. This is a life saver for one person
set up. Each of the light weight plywood boxes can be easily handled and
put together. Once the scope is assembled, tip it down horizontally, and
slip in the mirror cell.
The upper cage assembly is constructed of two plywood
rings separated by a short length of sonotube. The sonotube is
attractively finished with matte black. The standard focuser is a
very nice Crayford design. It moves smoothly and effortlessly. The
trusses come in pairs, configured in a triangle assembly. You attach
each pair on each side of the mirror box and then attach the upper cage
assembly. The trusses are constructed of hardwood dowels.
For attaching the components together, you get a set of
bolts with handles. They are all the same, so you don't have to
worry about which one goes where. The scope goes together very quickly.
One of the nice features about the Starmaster is that
the rocker box, the mirror box, and the upper cage assembly stack
together, one inside the other. The base boxes are much larger than
an Obsession, but this stacking feature allows you to take up much less
space in your van for hauling your pride and joy. I've seen these scopes
arrive in cars of various sizes.
The optics are first rate. Mirrors are supplied by
Zambuto and Pegasus. I've seen various mirror brands in Starmaster scopes
and they have all been very good. Rick inspects each scope under the
stars before he ships it to assure his brand's reputation. Rick also
spends time in the field with his customers. I've run into him at
local star parties and although I'm a loyal Obsession owner, he has been
extremely gracious with me.
The action on the Starmaster line is stiffer than an
Obsession or a Star Splitter. This isn't a good thing or a bad
thing. I prefer a one finger action but I pay the price when I put
in a heavy eyepiece. With a stiffer action, the total balance of the
scope is not such an issue. You can go from a heavy Nagler to a
light weight plossl and the scope won't move when you don't want it to.
Another nice additional option you can get is the GOTO
system. Starmaster is the only company offering this option for its
customers. It performs flawlessly. I've done everything that I can
do to trick it, but objects seem to pop right into the field of view every
time. The motors are quiet and make a delightful little chirping
sound at the end of a slew.
I've enjoyed using the Starmaster telescopes. I've
used a 14.5", 18", and the 20". The scopes give
superb performance. I highly recommend them. For the latest
