Again a quality piece of kit from SkyWatcher even the end caps are metal , a light and very usable addition to the already versatile evoguide 50ed scope .

Give your guide scope some love

I haven't had a change for first light with this yet, because of course it has been cloudy since this shipped. However, I love my EvoGuide 50ED so much more than other guide scopes (really I do!) that I felt the ED doublet deserved the accompanying flattener. This will still primarily serve as a guide scope for me, but I will also play with imaging using it.

Flat stars to the edge, very nice product. I just wish the specs were listed on the webpage. Does it reduce at all? What's the % ect. No info given. Frustrating. It does yield flat stars to the edge!


Please fill in the form below to ask a question.


Q1. Is this necessary if I use the EvoGuide 50ED only as a guidescope?

No. Guiding software is only interested in the centre of the star and is usually very tolerant of star shape so a flattener is not necessary.
