NEW Mk II Upgrades

  • Enlarged 1.5″ metal focusing knobs which allow you easy focusing.  They have a very pleasant thick knurl, which makes it a joy to focus.
  • Most refractors have one or two screws which dig into the eyepieces / cameras.  We’ve upgraded the connector to a three screw compression ring system to securely hold heavier loadouts

Details:

  • 90mm Aperture
  • 600mm Focal Length
  • F/6.6
  • Achromatic, Doublet Refractor Design
  • Fully Coated, Air Spaced Doublet with figured K9/F4 optical glass
  • Metal Dew Shield
  • Metal Finder Shoe
  • Beautiful, Textured “Raven” Finish
  • 1.5″ metal focuser knobs for very easy and precise focusing
  • Focus lock system
  • Rings and Vixen Plate – The rings on these are something special.  The red deluxe rings were made with love and are fully servicable, 33% thicker and stronger than similar rings found on other scopes, and have extended knobs and grips which make tightening and detaching a breeze.

This model is suitable for use as a guider, a finderscope, or as a standalone general refractor.

When comparing to an 80mm

The jump from an 80mm to a 90mm scope is significant, with 25% more light being gathered, a brighter image and greater reach and resolving power.  Every mm in this size category counts.  With this particular model, the improved glass also makes a difference, and the optical quality is better than you would expect and it is a very portable, satisfying size refractor suitable for both day and night use.
