Ok X-Mas is coming and Santa may bring me a new refractor. Which one would you pick between the SVX080T-3SV, the AT92 F5.5 and the SW Esprit 100?

They are all in the similar range focal length.

I currently have an ES ED80 FCD100 (for wide field -nebulas) and ES ED127 FCD100 (primary for galaxies and planetary nebulas). I am thinking to sell them both and get only one but EXCELLENT short-mid range FL refractor (80-100 mm range) and cover the same (approx) FoV  range of the two refractors just using either my ASI1600MM-pro (for wide field imags) and ASI183MM-Pro for galaxies  (my limitation is the average "seen" condition of NE Philadelphia area so I would never use the combination ASI183 with ES127 ).

 

Let me have your opinion please!

I have both the SW Esprit 80 and 120EDs. Lovely refractors that I would highly recommend.

 

I have no experience with the other two scopes you mentioned, though.

This thread under refractors may be helpful regarding the SVX080T

I have the Esprit 100, fantastic optics. Round stars from edge to edge with the ASI 1600 using the included flattener (and appropriate backfocus distance).

I can’t speak for all the scopes listed, but I received a new SVX80-25SV - the same scope with a 2.5” focuser several weeks ago.  My copy has some of the finest glass I have ever owned - perfect star test and a test report that says 99.3 Strehl.  I’ve owned Astro-Physic, TEC, Takahashi, and TMB refractors, and this scope from Stellarvue gives up nothing but aperture to those other excellent scopes.  I look for excellent corrected optics in a scope used to image.....these 80mm scopes from Stellarvue - I would highly recommend.

I sold my 80 and 102 APOs when I got the AT92.  It has the size of the 80 with the reach and power of the 102, speed of F5.5 native with Stellarvue 2.5 flattener and you can go to 4.3 with .79 TS reducer/flattener but 506mm is a good focal length for a lot of objects with the ASI1600.  For visual, you can go from 5.5 degree field of view with a 41 Panoptic to over 300x without image breakdown.  I consider it a swiss-army knife of telescopes.  I have also heard good things about the Esprit line and have seen some great images.  I also have had a few Stellarvue scopes over the years and have never been disappointed so I don't think you will regret any of the options.

This is an accurate description of the AT92.

I have one as well for visual only, possibly EAA. I cant speak on imaging but if you want a telescope that is super portable, great build quality, can do huge swaths of sky and then high power viewing, then you cant go wrong with the AT92.

They hit a home run with that one IMO.

Not to take anything away from the wonderful AT92, but maybe a used SV 90 fluorite. You can save $400-500 and get a new alt az mount and a nice eyepiece. Unfortunately there won’t be that new telescope smell. 😀

Also sold my 80 and 102 ED's for an AT-92. Its been an excellent refractor for me in a compact package. Also have an FC-60 which is my smallest scope, an SW-120ED and an APM 152ED.  all have their purpose. Visual only person for me.

 

The AT-92 works well on both my CG-4 as a mega portable set up and my Avx mount also.

 

The AT-92 is sharper then my AT-102 was at high magnifications. With my Big Barlow in front of my diagonal at about F/16.5 it takes magnification very well for star splitting. I don't feel that extra glass of the barlow in the optical train degrading the sharpness at all.

 

The AT-92 also has a premium focuser. It can take whatever you can mount to it and not sag or cause image shift or feel stressed. It can take my Big barlow in front of the diagonal, a 2" diagonal and the ES 25mm 100 degs eyepiece and focus effortlessly with all that weight off the back. It also rotates very smoothly, unlike most other focusers which seem to drag metal to metal. Its has the same color scheme but it sure doesn't feel like the focuser on my AT-102.
