  • The sturdy metal housing made of black anodized aluminum. Looking out not only solid, but is also very robust. A milled and knurled ring allows easy and precise fine focus adjustments. It comes with matching pipe clamps and a Synta-style mounting plate to make assembly and installation as easy as possible.
  • Have a built-in worm-focuser with Brass Compression Ring and 2 thumbscrews,45mm focusing range (10mm focusing range with micro-focusing Helical focuser, the rest is by a fixable, scaled drawtube) is made possible by an extremely precise focus adjustment. The mechanism has a determined orientation: This is mounted cameras or eyepieces - and thus also the area with your guide stars - not rotate during focusing.

This small guide scope takes does the job of a 'classic'
guide scope - but it is lighter and much easier to use! Previously, long and
unwieldy guide scopes were used to locate a guide star. But this is no longer
necessary! The sensitivity of modern astronomy cameras makes this possible.
You simply attach the mini guide scope onto your telescope like a finder. Or
you can use it as a convenient, large finder scope and spend less time
locating objects when visually observing. What is special about our new
Astromania guide scope? It has a built-in worm-gear focuser with 10mm
displacement, allowing very precise focus adjustment. The mechanism has a
fixed orientation - so there is no rotation of mounted cameras or eyepieces -
or also the field of view with your guide star - when focusing. Using the 60mm
Multi-Use Guide Scope as a Finder Scope ? The 60mm Multi-Use Guide Scope
conveniently doubles as a 60mm finder scope with the addition of an optional
1.25"-barrel eyepiece inserted into the focuser collar. You may need to slide
the extension tube out nearly all the way to reach focus with the eyepiece.
You will need to align the finder scope with the main telescope before
starting your observing or imaging session. You do that by adjusting the three
thumbscrews on one or both of the bracket rings until a distant object in the
main telescope’s eyepiece is also centered in the finder scope’s eyepiece. Use
of an optional crosshair eyepiece is helpful in achieving exact centering of
an object. Attaching the 60mm Multi-Use Guide Scope : The 60mm Multi-Use Guide
Scope’s mounting bracket has a Vixenstyle dovetail bar that can be mounted to
your telescope in different ways. First, it fits the standard dovetail finder
scope base included on many telescopes. Simply slide it into the dovetail
base, then tighten the thumbscrew on the base to secure the guide scope in
place. The bracket’s dovetail bar has one ¼"-20 (center) and two M8x1.25
threaded holes for attachment to an optional universal dovetail plate. In the
guidescope is mounted on the top plate of a telescope. Aiming the 60mm Multi-
Use Guide Scope : The 60mm Multi-Use Guide Scope is mounted in a dual-ring
aluminum bracket that has six nylon-tipped thumbscrews to secure the guide
scope in place. Although you may never need to do it in order to find a guide
star, you can adjust the direction the guide scope is pointed within the
bracket by alternately loosening and tightening the three thumbscrews on the
front or back ring (usually you won’t need to make adjustments on both rings).
Just make sure that all six thumbscrews are tightened before you begin
guiding. Do not over-tighten them, however, or you could strip the screw
threads! Another method of attachment : Another method of attachment is to
bolt the guide scope bracket to an optional universal dovetail plate, which
you mount on top of your telescope. The mounting bar has three threaded
through-holes: the center hole has ¼"-20 threads and the two larger holes on
either side of center have M8 x 1.25 threads. To attach the guide scope
bracket to a universal dovetail plate, one way would be to insert a ¼"-20
socket head capscrew of proper length up through the dovetail plate and into
the center hole of the bracket’s dovetail bar. Tighten the bolt firmly with an
Allen wrench. Then install the universal plate onto your telescope’s tube
rings or radius blocks. Alternatively you could attach the bracket using two
M8x1.25 screws in the same manner.   Read more The 60mm Multi-Use Guide Scope
features a precision helical focuser that makes it easy to focus your guide
stars quickly and precisely. The focuser, made of machined, anodized aluminum,
is the “non-rotating” variety, meaning the guide camera does not rotate when
focus is adjusted, but rather moves in or out in fixed orientation, which is
important for hassle-free focusing. You don’t want stars rotating in the field
of view when you’re trying to focus! Drawtube travel of the helical focusing
mechanism is 10mm and the motion is extremely smooth and fine. The built-in
extension tube can add up to 35mm of additional length, to allow focus to be
achieved with most autoguiders available on the market as well as 1.25"
eyepieces for use of the 60mm Multi-Use Guide Scope as a visual finder scope.
Just loosen the extension tube locking thumbscrew, slide the extension tube
out to the desired length, then re-tighten the thumbscrew. When tightened
down, you should not notice any flexure in the extension tube; it is
remarkably rigid. The top of the extension tube features an engraved
millimeter scale to aid in returning to the exact extension tube length needed
for critical focus, should you need to switch between eyepieces and
autoguider. Make sure your autoguider is powered on and connected to your
laptop computer, and that the software you will use for autoguiding is up and
running. Also, make sure the focus lock thumbscrew is not tightened down. With
the imaging software set to take continuous exposures, rotate the knurled
helical focus ring clockwise or counterclockwise while you watch the star
images themselves or the reference numbers from your software on your laptop
screen. If you can’t see any stars, you likely need to move the extension tube
in or out slowly until you see some, then continue with the fine focusing
using the helical focuser. When the stars become reasonably sharp, or you’ve
reached the lowest FWHM, you’re done! Once focus is achieved, the focus lock
thumbscrew can be lightly tightened to ensure the drawtube remains set at that
position,although this may not even be necessary.There’s little need to
tighten this thumbscrew firmly since most guide cameras are relatively
lightweight, and doing so could put sideways pressure on the drawtube that
might knock your carefully set focus off a bit. For best results we recommend
focusing the guide camera at the beginning of your imaging session, following
the focusing procedures in the imaging software you use for astrophotography,
such as MaxIm DL, PHD Guiding, or Images Plus. Caring for the 60mm Multi-Use
Guide Scope : To keep dust from getting inside the guide scope and from
accumulating on the objective lens, keep the front and rear caps installed
when the guide scope is not in use. We recommend storing the guide scope in a
padded accessory case. Cleaning the Lens: Although it shouldn’t need cleaning
very often, you can clean the front lens of theguide scope with any quality
optical lens cleaning tissue and optical lens cleaning fluid designed for
multi-coated optics. Never use regular glass cleaner or cleaning fluid
designed for eyeglasses. Before cleaning with fluid and tissue, eject any
loose particles from the lens with a blower bulb, compressed air, or a soft
brush such as a LensPen. Then apply some cleaning fluid to a lens tissue,
never directly on the optics. Wipe the lens gently in a circular motion, then
remove any excess fluid with a fresh lens tissue. Oily fingerprints and
smudges can be removed using this method. Use caution, as rubbing too hard may
scratch the lens. Never re-use the same tissue. Read more
