The Altair Astro 60mm finder also has many more features than your average finder scope:
- This finder is right angled for more comfort, with a corrected field (i.e. not mirror-reversed like other finders), so objects actually match their orientation in your star chart.
- The focuser can also be rotated 360° and locked in seconds (requiring some re-alignment afterwards). The 10mm larger objective and a little extra power compare to 8x50 finders, yet has almost the same size and weight.
- The included quick-release finder base has 4x 4mm slotted holes in the base allowing you to fit it to most telescopes on the market. (The mini-dovetail wedge on the bracket will fit any GSO or Skywatcher telescope directly in fact but we suggest you use the included base if it fits the tube, because it has 2x clamping screws, for better alignment).
- The CNC machined bracket is light yet rigid to keep alignment. Nylon tipped screws do not damage the durable high quality and moisture resistant powder coated aluminium tube.
- All objective lenses are anti-reflection coated and the tube and dewshield are internally blackened to increase contrast. The included illuminator has a variable setting, which illuminates the cross hairs in the eyepiece. The included eyepiece has a dark field illuminated cross-hair, so you can easily see it glowing faintly against the background sky, an upgrade for standard finders with dark cross-hairs.
- The high quality 1.25 FMC illuminated eyepiece has good eye relief for glasses-wearers, and a wide field of view. It has a side-port to screw in the included variable darkfield illuminated reticule, and the finder can be very easily focused, using the included helical focuser integrated with the prism diagonal.

The Altair Dichroic Solar Energy Rejection Filter or D-ERF protects your telescope and solar imaging equipment from excessive heat build-up when solar imaging or observing with your Daystar Hydrogen Alpha Quark, or other Hydrogen Alpha Etalon filters.
- Reduces approx. 98% of heat reaching the optics to keep Etalon from drifting off-band and protect your equipment.
- 30nm FHWM Bandpass at H-alpha (H) wavelength of 656.28 nm (Full Width Half Minimum) Transmission: ~95.5%
- 40nm FHWM Bandpass with CWL at 395nm covering Calcium H-Line and Calcium K-Line wavelengths. Transmission: ~90.5%
- UVIR blocking OD3 0.1% @400-1100nm blocking over 98% of heat to your 3rd party Etalon at eyepiece or camera end, E.g. Daystar Quark). Please note it's your responsibility to use a proper commercial Etalon with this product, and to follow the manufacturer's instructions.
- Visible light blocking: OD4 0.01% @400-700nm to reduce reflection effects and over 98% of heat.
- Diameter 140mm Thickness 12.0mm (required to achieve surface precision)
- Multilayer coatings with SiO2 protective overcoat.
- ERF Holder cell included with soft tip threaded knobs. Tough and very light, easy to disassemble for cleaning the filter with optical wipes. Cell does not put any tension on the optics.
