Product description

Maximum functionality in one system

Dew cap with stray light protection

  • Extends the look of the Dwarf 3
  • Reduces condensation in high humidity conditions
  • Minimises lateral stray light
  • Improves contrast and image quality during longer exposures

Especially during night-time sessions with high humidity, the extended design ensures more stable conditions at the front lens.


Integrated 2" filter insert

  • Suitable for standard 2" astronomy filters
  • Secure, play-free fit
  • Ideal for narrowband or dual-band filters
  • No separate filter system required

This allows you to flexibly adapt your setup to your sky conditions – perfect for emission nebulae or light-polluted locations.


Precise spike mask

  • Produces clean, aesthetic diffraction peaks
  • Ideal for star fields and deep sky photography
  • Optimised for the appearance of the Dwarf 3
  • Easy to insert and remove

For anyone who wants to give their recordings a distinctive, professional look.


Separate dark frame cap

  • Light-tight design
  • Perfect for capturing dark frames

This significantly improves image quality through clean noise correction, especially during longer integration times.
