Help me choose

As the topic implies, I am looking for help in choosing a complimentary refractor to my AGOptical 14.5" iDK (2464mm) to be used in a side-by-side tandem setup at a remote site. The goal is a high quality (prefer readily available) wide field scope. I was thinking something along the lines of a baby FSQ or Stellarvue 102T Raptor. I would likely be using a APS-C camera with it initially but might switch to full frame at some point.

Let the fun begin! Thanks!

Okay, let me try and "help" with what I'm thinking/looking at. Deciding between a Baby Q, a Vixen VSD90, or Stellarvue SVX-102.  Again, goal is for a complimentary wide field imager to ride along side my iDK.

all three of your options look good to me

it really depends on what focal length you want

I'm going to have to load all three into Astronomy.tools and compare. I have no direct knowledge of any of them other than "reputation".

Does the Baby Q cover full frame?

From what I have read with the included flattener or the new reducer, yes.

try Telescopius; it's much better

Do you plan to replace the focuser or use a bolt-on type? If you want to keep it open for full-frame one day, that will limit the field a lot more. 

I really like the specs on the new reducer for the Baby FSQ. i've seen some solid imaging from the Askar 107phq if want to save a couple thousand

no.. it doesn't. And it's iffy with the reducer across aps-c on modern cameras with small pixels. 

Its a fantastic scope with a qhy8 or qhy10, or a sbig stl-11000 where pixel sizes are greater than 6 or 7 microns, but the fsq85 will usually show astigmatism with the small pixels of the imx571..

There are plenty of better options at lower prices. 

Takahashi have to do a new version of the FSQ if they wish to retain the title they've held for decades as the go to top of the line refractors. 

I would personally look at the vixen vsd 100 f/3.8 if you're looking for wide, or the pentax 100sdp/sdph

From what I've heard, the newer Baby Qs have pretty good focusers. I already have a FRA500, which is very nice and I plan to keep it here along with my C8 Edge in my backyard observatory and have it as a travel scope as well. Just looking for that "little bit extra" for the scope going out west.

That's interesting, everything I've read says the Q with the flattener (kind of ridiculous requirement for a Petzval) or the brand new designed for the Baby Q reducer will do full frame just fine.

The flattener on the Baby q was because the scopes were poorly correct when they were released, and a corrector had to be released to fix the issue.

Mine did a very average job with a 35mm 36mp sensor, and marginally better with a 26mp sensor.

They vary from scope to scope much more wildly than the 106mm, but the 106 is also not fantastic with small pixels...

They are awesome scopes, but there are better scopes for the money, make no mistake.

**hi

here is one of my setup

takahashi  baby-Q   FSQ 85 EDX  ( 450mm)  flat 1.0x or RD-QB 0.73x New reducer for "Baby-Q ( 328mm)

camera  zwo 6200 full frame, chroma filter 50mm ( 3nm )  SQM 16.84

perfect corners  , just need some precision with the back focus( with  Fine-Adjustment Rings)  ,and the pattern light house ( big stars) live with that

and  M54 for all imaging train , if you need more info let me know

with asi air pro plus you can use full frame ,or APS-C FOV, selector mode 
now I'm moving for NINA

CS, Brian

And it's here safe and sound. Of course now I'm going to have to deal with a month or more of clouds.
