Background: I’ve only been taking images of DSOs for six months now and really enjoy the whole process. I’m looking to add to may astrophotography equipment but I am not sure which triplet refractor to add to the tool box. I have been looking at the Sky-Watcher Esprit 120mm triplet and the Explorer Scientific 127mm carbon fiber triplet. I could really use some unbiased input on either of these telescopes or other options that are in the same price and quality class.

 

Thank you

Tatoo

" unbiased input".....?????   Since 99% of the comments you read on CN are 'anecdotal', (and SHOULD be, since they should be based on personal experience, and NOT 3rd party hearsay, myths, or what was 'read somewhere'), asking for unbiased opinions is near impossible.   When one. Of us compares 2, or even 3, scopes, we DO form opinions.

   In any event, having owned these, and over 350 other scopes, here is my 'personal take on the question:

 

     I have owned more than a Dozen Explore Scientific scopes, and over 2 Dozen Skywatcher scopes,  of various optical designs.  I continue to enjoy just about every Skywatcher scope that comes my way.  I stopped using ES scopes almost 5 years ago.

      (But I love their 68° and 82° eyepieces)

Ok I’ll guess I should say experienced based opinions are what I am actually looking to get.

 

Thanks

In my experience ES suffers from subpar quality control and less than perfect color correction on their optics. I vote Esprit.

I have an Esprit 100mm and use it for astrophotography.  I have no issues with the scope.  I agree the ES suffers from QC and color correction problems.

I know my buddy Ron may agree with this after his Esprit 100 troubles, but look into the Photoline 130/910 by TS optics.  It was recommended to me by someone earlier this year  who just got IOTD on astrobin using that scope actually haha.  Amazing optics especially for the price.   If you go the Esprit route, make sure you don’t hesitate to contact Sky-Watcher about anything sub par and make sure you get what you pay for with that scope.

What was wrong with the Esprit 100?

Happy with my Esprit 100. The Esprit comes with a field flattener (US models) which might be a consideration.

Not being able to get perfect stars in all the corners, due to something like the focuser not being aligned with the rest of the scope.  Let me see if I can dig up the relatively recent thread about it.   It’s one of those things where 99% of the time you’ll get a fantastic scope, but keep an eye out for that 1% chance you get a crooked focuser.

I had an ES ED102CF and currently have an Esprit 100.  The Esprit is much better.  The ES focusers are very substandard, and FCD-1 versions have bad CA.  FCD-100 should be much better.

 

For AP, this is a very easy choice, Esprit 120.

I have used the Esprit 120 for a couple of years and am really happy with it. Built like a tank with great optics (for the price point) and a good focuser you won't have to upgrade.

I have a William Optics 132 and really like it.  

 

At 925mm FL native and with a focal reducer it is 660mm these are pretty good combination for a lot of targets.

I live 3 hours from explore scientific, and own an esprit 100. The carbon fiber ES is lighter weight, but it doesn't come with a field flattener and the stock focuser is not as good as the esprit by a good margin. The esprit are heavier, but built like a tank and very rigid which is what you want for imaging and comes with a flattener designed for that scope and the esprit 120 reducer can handle full frame.

I had the SW 80 and 100 Esprit, solid build and focusers.

 

 

After buying the ES "carbon" comet hunter, and seeing the toy like mechanics I promised myself never to buy another ES scope again. The focusers are probably worth $30, the mechanics are very poor.

I had both. No comparison: ES127  (FCD100) quality is far inferior, mechnically and optically than the SW120. Don't even think twice: go with SW.

Thank you everyone. This has made the choice a lot easier. I ordered the SW 120 and now the wait begins.
