About this product

Model:  bst_sg_2x_short_barlow
Part Number:  SP10585

Please note this barlow is occasionally branded 'Astro Essentials'. 

Remarkably high performance-per-£! 

A 2x barlow fits in-between the telescope and eyepiece and doubles the eyepiece magnification. 

This compact 1.25” BST StarGuider 2x barlow with fully multicoated 3-element air-spaced optics features enhanced colour correction, high contrast and excellent light transmission. 

It's compact size makes it suitable for use not only with Newtonians but also telescopes fitted with a diagonal such as refractors and Schmidt-Cassegrains. 

It also has 26mm clear aperture so can be used with long focal length eyepieces with minimal vignetting. 

The sturdy anodised aluminium body uses an anti-marring brass compression ring and thumbscrew to grip the 1.25” eyepiece securely. The smooth-sided nosepiece is threaded to accept 1.25” astronomy filters. 

FEATURES

  • Doubles the magnification of 1.25” astronomy eyepieces. 
  • Provides longer eye-relief and improved edge sharpness at a given magnification. 
  • 3-element design offers superior colour correction compared to two-element Barlows. 
  • Fully multicoated optics for high contrast and maximum light transmission. 
  • 26mm clear aperture reduces vignetting.
  • Compact design suitable for use with Newtonians, refractors and Schmidt-Cassegrains.  
  • CNC-machined anodised aluminium body with anti-marring brass compression-ring. 
  • Nosepiece threaded to accept 1.25” filters.

It's a gift
Tuesday, 23 November 2021  | 

Firstly can I say how happy I am to have found your website. I sent an email regarding stronger Barlow's and lenses for a telescope I purchased for my husband which is a great little telescope. First thing the next morning I got an email from Ian with 3 recommendation's which I purchased they are going to be a gift for my husband so we haven't used them yet but I'm sure the will be grand as has everything I've bought so far. I would highly recommend your website to anyone looking to buy a telescope ect or if you have a question your very friendly and knowledgeable staff are only to happy to help. Once again thank you ☺️

Really impressed with the quality feel of these eyepieces. They are a 110% improvement on my previous eyepieces giving a bright, clear and sharp view.

Effective

Nicely made for the cost and works well to give a sensible increase in magnification. Despite the slight and expected degradation in the image when in use, I consider it a worthwhile addition to your box of tricks!

Excellent and Affordable
Friday, 22 January 2021  | 

This is a great little barlow lens, I am quite new to astronomy and got this to go with my 25mm and 10mm eyepieces (which were supplied with my scope) to an amateurs eye I can't see any problems with it, it feels like good, solid build quality and I have had excellent views of the stars and the moon when using it.
