For visual only, how does the FSQ85 compare to all other 80 to 90mm refractors?

Can’t make the comparison. But I can tell you my TS Optics 90mm triplet would take some beating.

Hate to say it but a little pointless.

I have a Megrez 90 and I am not going to go buy a Tak or any other to do a comparison and give you the result. Although I could compare a Tak to both Meg 90 and GT 81 as I have one of each of the WO's.

 

These questions keep appearing and it would be rare that a direct comparison is possible. Like EQ6-R or CEM60, people do not have both.

 

One other person about 2 years back gave the reply:

 

Let me just pop out and buy one of each and I will let you know.

 

The comparison was again on 2 rather expensive scopes, up in the $4000 area. Think one was an Astrophysics.

Maybe someone has been to a public event where they might have been able to take a look?

HERE is a comprehensive user review of the FSQ-85. Google a review of other 80-90mm scopes that you are interested in and compare the two.

Widefields are wonderful. In focus travel is a thing to try out with your personal eyepieces and diagonal, some require a bit more than is available to reach focus. High power views are not quite as good as in the best Tak Fluorite doublets. The form factor and build quality are exquisite, perhaps the finest of all 85mm ever made.

I have used the Baby Q visually a few times, it is very sharp indeed. The only issue is the short draw tube travel.

I compared it to the FS78 and FC76DC as well as the Fc100DL.  If I was into imaging but wanted to do occasional visual then the FSQ85 would be great...

I don't have anything 90mm. Next step up from 85mm for me is 106mm. But I do have the FSQ-85ED, a LOMO 80/480 and a LOMO 80/600. I use both LOMOs with TSFlat2 to obliterate the field curvature in the triplets.

 

The Tak Baby-Q gives beautiful, sharp views, and when I want to go for more mags from its 450mm FL, I add the flawless Tak 1.5X ED Extender. The LOMOs have an icy, super-contrasted view. The Tak FSQ shows more color nuance, is equally sharp as the LOMOs but yields an edge in ultimate black-velvet-sky contrast to the LOMOs, in exchange yielding a more artful presentation. These differences are subtle and you need 1st class eyepieces to notice them.

 

On balance, no disrespect to my two excellent LOMO 80s, if I had to have only one, the FSQ85 would stay.
