Product Details

  •  Evoguide 50DX Guide Scope Astrograph

    Sky-Watcher has transformed their signature doublet telescope design and packaged it into a lightweight guide scope! These APO refractors will give you beautifully detailed and contrast-rich views of deep-sky and planetary objects, leaving you in awe of the wonders of the universe. You can easily mount it to your guide camera using convenient M42 rings on the back of the scope, and a large single-speed focus ring to achieve perfect focus. While it was initially designed for guide cameras, the EvoGuide 50DX APO Guide Scope Astrograph can also be used to shoot fast, low focal length astrophotography when used in conjunction with a focal reducer (not included), giving you spectacular wide-field images.

Huge improvement over previous guide scopes!

Received my scope from OPT last week and everything arrived as expected. I found the scope easy to setup and focusing was a breeze. My autoguiding average last night was less than .5 arc seconds total rms for a 2 hour session where previous guide scopes left me with .8 to 1.2 rms. Granted I was using the recent multistar guiding feature in asiair pro beta firmware release but acquisition of suitable guide stars was much easier with the added focal length and optical quality of this scope. Couldn't be happier! Highly recommended.
