Product Description

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.

Focusing the 50mm Multi-Use Guide Scope

  • The 50mm 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 30mm 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 50mm 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.
