Skywatcher Evostar range verses the Skywatcher Evostar DS-PRO Series

[Anser]

After considerable deliberation including much advice on this forum I am erring toward a refractor 120.  Size not a huge issue but I am looking for visual clarity on planets not worried about DSOs at this time.

What is the difference between the Skywatcher Evostar range and the Evostar DS-PRO Series.  The latter is more than double the price and I could afford an Evostar 150 but not an Evostar 150ED DS-Pro.  

Would I be better going for a Sky-Watcher Evostar 120ED DS-Pro or a Sky-Watcher Evostar 150?

Thank you

Planets will show significant Chromatic Aberration  (CA) in the basic Evostar telescope.

A smaller aperture ED DS-Pro is by far the better option, CA is significantly reduced and the rainbow effect is all but removed.

 

Below is Venus in the basic Evostar 150 (I used to own one) , it was better suited to DSO where the far less bright targets did not suffer the same CA issues.

The basic Evostars are achromatic doublets whereas the DS-Pro are all ED doublets. The 120ED DS-Pro will produce vastly superior views compared to the basic Evostar 150.

DS-Pro all the way.  If you decide to image down the road you won't have to change the scope

I have owned the evostar 120 twice~ guess i must like that model a little. My 2nd one is a keeper.

Against  good advice from SGL i bought a used evostar 150. I like that also, but it's a big lump to cart in & out~ which is what the advice pertained to.

The weak point of the standard evostars for me is the focusser, which can be changed, but at additional expense.

If you have the money the 120 ed pro is better with a much smoother focusser. It's not 4x better though.but is 4x the price!

Have you factored in the cost of a mounting? 120/120ed  on an eq5 is minimum for visual use IMO.  Ideally you'd get something bigger & heavier & more stable.

There's a reason i've stuck with the standard 120,  It's a pretty good visual scope for not a massive amount of money.

A 120ed could be a 'for life' scope though.

Thanks all.  I am thinking  Sky-Watcher Evostar 120ED DS-Pro with a SkyTee-2 Alt-azimuth mount.  This pushes my budget of £1500 particularly if I want additional eye pieces!  It seems to be the best compromise of clarity, aperture size, overall size and weight, cooling time for planets in the UK skies.  

No one has them in stock so I am looking secondhand  as well.

If you find two, let me know! 😁

The ED120 is the better scope hands down.
