The Altair Astro 60mm finder scope is an upgrade to standard 50mm finders. It delivers almost half again as much light to your eye, resulting in a brighter image.
The straight-through version is designed for visual use. It has a large easy-to-grip 2" helical focuser which accepts standard 2" and 1.25" astro eyepieces.
NOTE: This finder does not include the illuminated eyepiece.
The Altair Astro 60mm finder has many more features than the average finder scope:
  • A large 2" Helical Focuser with 2" to 1.25" adapter, which can be rotated 360° and locked in position. 
  • The included quick-release finder base has 30mm width cross-slots with a 5mm width, allowing mounting to most telescopes on the market with M4-M5 screws.
  • The base-bracket is cross-slotted, so the finder scope can be mounted on telescopes with different mounting hole orientations (i.e. parallel or 90 degrees to the optical axis).
  • The mini-dovetail wedge on the finder stalk will even fit the existing finder bracked on most telescopes directly, without the base. This includes most older-model Skywatcher finder bases which are cast as part of the focuser.
  • All objective lenses are anti-reflection coated, and the tube and dewshield are internally blackened and baffled to increase contrast.
  • The finder bracket rings are light, yet rigid enough to keep good alignment. Nylon tipped screws are included, which won't damage the paint on the machined aluminium optical tube.
What's included in the box:
  • Optical tube with 60mm F3.75 Fully Multi Coated doublet lens, rotating / locking rear assembly.
  • Large smooth 2" helical focuser with compression ring so as not to mar your large 2" eyepieces or accesories.
  • 2" to 1.25" eyepiece adapter with brass compression ring for standard 1.25" astro-eyepieces.
  • Special dual-clamp mounting bracket fits most telescopes on the market and all Altair telescopes. 
  • 2x machined aluminium tube rings with 6x Nylon tipped adjustment screws.
  • Mini-rail to connect the tube rings.
  • Comes in a tough carboard box with foam cutout, which is worth keeping for storage.
Q: Can the straight-through finder be used as a guide scope for autoguiding? This finder scope can be used for autoguiding with wide field lenses and telescopes up to about 400mm but it's intended for visual use. For longer focal length imaging we recommend the Altair Miniguider and Right Angle Correct Image (RACI) finder which includes a Precision Locking Camera Focuser. This focuser is more rigid than the helical focuser, and cannot become de-focused once locked.
Q: Can I attach the Altair precision camera focuser to the straight-through finder for autoguiding? No you can't, because the rear assembly has a large diameter rear thread which is incompatible with the Miniguider Precision Locking Camera Focuser.  If you want to autoguide with maximum precision up to 1.2m focal length or more, you need to buy the Altair MiniGuider 50 or 60 which includes the precision locking focuser, or the Altair 50mm or 60mm RACI finder (which has the correctly threaded rear assembly).
