That’s counterintuitive...adding more elements in the optical path improves contrast?! What going on there?

Contrast it may well improve by concentrating light even better to where it should be and not letting it get to where it shouldn't be. OTOH, I'd be as surprised as you are if overall image brightness increased somehow by adding more glass. These two variables are by no means tied together. One can very much increase while the other decreases.

Two weeks with the FOA-60

....

 

What a beautiful setup! Love it!

Can you please make another photo of a whole setup with the tripod? That would look nice.

Thank you, Sergey. Of course, I’ll post a picture of the setup.

Simply wonderful.

 

I use it mostly with the Evolution mount, it is very light, precise and very very comfortable.

I got a bit carried away accessorizing my FOA-60Q but it's worth it. The tube balance weight is off one of my Unitron 2.4" (60mm) scopes from the 1960's and fits perfectly on the 68mm diameter tube and weighs in at 1.5 pounds (680g). The FOA-60Q normally sits on my Tak PM-1 mount which is a great combination but I was trying out a few scopes on the SW EQ6R mount one evening and it was rock solid.

Wow what a beauty!! Very nice set up there.  Definitely way overmounted though :p

Beautiful setup, Steve. 

 

Here is a more complete view of my rig. Shows the FOA-60 mounted on a Vixen AP WM and Vixen APP-TL130 tripod.

It looks beautiful! Vixen AP mount is a good match for the FOA-60.
I can imagine how cute it will look with the folded down legs of the tripod.

Thanks Matt, we both know that the FOA-60Q goes beyond looking good, the views through this scope are truly amazing. I was fortunate enough to have a perfect viewing evening a couple of nights ago and the ever popular M42, Eta Carina, Herschel's Jewel Box, Omega Centauri and various doubles looked brilliant. To see perfect little spheres with perfect diffraction rings on a perfectly black background is awe inspiring. Sorry for all the "perfects" but this is a perfect little scope, IMHO.

That's perfectly fine Steve, I concur  flowerred.gif

Stop it you guys!

 

I keep telling myself I don't need an FOA-60. lol.gif

 

If they release an FOA-76 or FC76-DZ then I know resistance will be futile. grin.gif

I ordered a FOA 60q and it should arrive this week. I'm just trying to decide between the Tak prism or the Baader Zeiss spec. Opinions?

Ken, I use the Tak prism and the Baader T2 Maxbright mirror with mine, I had the Zeiss spec prism before but found the Maxbright to be better with my Zeiss binoviewer.

To those who own the FS-60Q and the FOA-60Q, how noticeable, in something as scientifically stated as possible is the difference in viewing.   Adjectives like sublime will not help me.  The reason for the question is that I really like the option of turning the FS-60Q into a FC-76Q with the addition of the FC-76DCU--something the FOA cannot do.  Also, I think the FS will have an easier time with astrophotography.   The attractive alternative would be for Takahashi to make a FOA-76DCU to convert an FOA but I do not think that will happen anytime soon.

I had the FS60Q and now have the FOA60Q.  The FOA is a little bit sharper and this allows for a bit more magnification to be used. The FS60Q  would be fine for up to about 150x, the FOA Q is still perfect at 180X / 200x.  Not scientific, just my personal experience, after owning a  LOT of Taks (5 FS60 series and 2 FOAs)

I also used the FC76U with the FS60 tube and focuser and built the first FC76DCUQ which Tak copied later....

This is going to sound crazy....but if I made an adapter to screw the 80mm diameter 76DCU objective onto the 68mm diameter tube of a FOA-60 can I make it come to focus and will it affect the light path?

 

In your opinion, is the "little sharper" worth $600?  Since the FOA is significantly slower can you notice a difference in contrast?  Both FC and FOA are color free to the edge with Q extender?

Thank you.

I think the drawtube would vignette with the FC76U attached as the focal point of the FC76U would require the draw tube to be in the retracted position.

 

Is the $600 worth it ................. for me it is, but that might not mean it is for you........... I plan to keep the little FOA60Q as a G&G for the rest of my astro days so I wanted something that approached perfection.

It does not tell you everything, but examine the spot diagrams if you want a quantified read:

 

FOA-60Q here:

http://www.takahashi...28_foa-60q.html

 

FS-60Q here:

http://www.takahashi...ews_100806.html

 

Visual difference will be considerably narrower to you than suggested by the differences in the spot diagrams. But, yes, the FS-Q is visually incisive; the FOA-60Q is sublime.
