Re: Anything about the Astro Tech 111 mm ?

I think that a scope in that class should perform well with a large chip! Otherwise what refractors can?
John is right. The only other one I can think of and it's 5mm smaller is the Pentax 125 and it's $3000 more than the 130 and $5000 more than the 111. It's also a 4 element setup with a built in corrector so it's really not even a valid choice.

Which field flattener you recommend with it and with the AT 111 (if anyone has an idea)
Both Andy and I have used the 111 with the TV .8 reducer flattener with some decent results. As this was the only unit either of us had on hand that's all I can add to that.

You tried both scopes right? What differences can you highlight?
The optics and color correction are both better in the 130 as they should be and is no surprise. There is no competition in the focuser department as the 130 offers the absolute pinnacle of focusers in the Feathertouch 3545. The 111's is VERY nice for the price point and won't dissapoint. It carryies a 40D with no sag or shift but it's just not the FT. I like the lens cell better in the 130 than the 111 but the 111's is still a nicely done unit. The tubes are very similiar in fit and finish.
