About this product

Model:  ae_dew_shield_4
Part Number:  ae_dew_shield_4

Astro Essentials premium quality flexible dew shields, made in the UK. 

Robust design using modern materials for high performance and long life!

A dew shield prevents the formation of dew on your telescope optics.

It also prevents stray light from entering the telescope.

Features include an inner black felt liner that reduces reflections for maximum contrast. 

Wrap the dew shield around the end of your telescope tube near the optics and secure it with the integrated Velcro. 

Dimensions are 45cm long and 16cm wide. 

Please check the circumference of your telescope to ensure it will provide a good fit (a few cm are necessary for the velcro areas to overlap). 

Note: the photo is representative; the actual size may differ. 


  • Suitable for use with most 4" / 101mm diameter telescopes.
  • Velcro ensures a snug, secure fit.
  • A rubber trim also prevents slippage.
  • Internally flocked with black felt to prevent reflections.
  • Smooth inner fabric protects the telescope's finish (doesn't scratch or mar the surface).
  • Lays flat or rolls up for easy storage.
  • Two years no-fault replacement warranty.
