New TS 110 f4.8 APO

[900SL]

Here's an interesting (and expensive..) 110 mm APO from TS.

The OTA consists of a FDC 100 f6 triplet. A dedicated 4 element  full frame reducer is used to bring the FL down to 530mm at F4.8.  

Mechanics appear similar to the recent 96/102/106 FDC and CF  apps

Looks like it's a few months before these start to appear.

Targeting the FSQ and AP110 as a lower budget alternative? 

I'll be interested in real world reviews once it gets out in the wild (there's one over on CN at the mo, may be an advance  sample)

FSQ 106 is at F5 without a reducer, lots of scope at F6. 

I was not going to post the above, however I then saw this:

I like the price available on request.

Looks like a sharpstar build?

Interesting. From the specs and the description, maybe a response to this.

EDIT: I see the OP has already made this link - I missed it on first reading!

Looks like astrotech have a version and accordingly will tecnosky and a bundle others. The Tecnosky version is available now

They seem to be variation on the OWL/CF APO/GEAR etc. etc. design, the 110 looking like a short tube based on the 90 mm scopes, with inbuilt 4 element flattener rather than separately screwed on. Maybe there is a difference in reducer/flattener configuration, but pricey perhaps. Its a tidy looking instrument and if long perng will hopefully be well made like the current triplets. Spot diagrams look good and frontal cell tilting is there. The 102 triplet come with 3.7 in focuser as standard, but the 528 mm focal length at f/4.8 is enticing - almost band on the fsq values.
