I wonder if the AT 80ED F/7 will be similar to the Lunt 80ED. My understanding is that the Lunt uses FK-61 glass as well?

I don't know the glass for the Lunt, but from using an Orion 110ED f/7 (probably made by Kunming?) with the equivalent of FPL-51, I would expect it to be a little short of visually apochromatic as compared to the Orion 80ED f/7.5 with FPL-53.  Yes, I know that 110 at f/7 is going to be worse, but even stopping it down to ~90mm (~f/8.6) didn't eliminate the color although it did make it less obvious.  Per my calcs that is about equivalent to what I would expect the AT 80ED to yield in the way of color, assuming both are well executed.

 

It still looks like a very good package and for an excellent price, but I would expect a small amount of color for my eye compared to the Orion 80ED (which I don't detect color in.)  The AT's focuser is likely to be better, and it wouldn't surprise me if the figure was as good or better than the Orion 80ED.  The extra baffling in the AT could provide some benefit as well.   It would make for an interesting comparison.

Yeah, i'm considering getting an Orion 80ED as a grab and go scope as i've heard great things about them. At $449 they are a good deal with the FPL-53

Don't forget rings and dove plate to make it apples to apples, sorta. Not sure about the dew shield.

FWIW, Orion currently offers as a “second” ED80 for $359.99.

The Orion doesn't have a 2 speed focuser so if you want to upgrade that your looking at another $150. That's what makes the AT80ED such a bargain. If it performs like the AT102ED you won't see a lot of CA. At F7 it can go a little wider too.

What size rings does this scope take?  I have some 90mm rings.

You shouldn't need them if the description is up to date:  "split tube rings with detachable Vixen-style dovetail for installation on virtually any mount"

If the question refers to Orion 80ED, it comes with no rings. The Vixen-style dovetail is screwed into the tube directly and it’s rather small (short). You usually order it with a set of rings (and preferably longer dovetail), 100 mm by Orion (though one can go with any manufacturer’s rings of that size). Amazon charges $41.18 for the Orion’s set.

October with our shipment of scopes.  Pricing is good and it will have the same focuser and quality as the 102.

 

Well, guess what month it is now (though it still feels like August here).  Any updates?

When asking about another scope that I have on order, I was told that there is a shipment due during October, but there was no ETA available. This was last week. I am assuming that the AT80 would be on that shipment, but I have no other information other than my own assumption.

I just ordered one of these, it sounds like a great grab and go scope for the money.  The website didn't give any indication of an ETA, nor did it have a picture.  Does anyone have theirs yet?

Awesome... they still aren’t out yet. Guess I’ll have to really think about pre ordering mine now before they already run out.

Probably not a bad idea.  If they perform well, it's a real bargain in my opinion.

 

I ordered an Astro-Tech Voyager 2 altazimuth mount with it.  I assume this would be an appropriate mount, what do you think?

Oh yeah, that will be fine for it, I’m debating on just getting another Versago ii to use with this one as well or possibly something different.

FYI, Pete at Astronomics just told me the scopes are "still a month or more out".

I had a similar answer from them a couple of days ago. Later this month or sometime in December. This is why I decided to go with a Zenithstar 73. I really wanted to finish out my new kit before winter sets in fully, so I did not want to wait much longer.

I own one of the original AT80ED scopes ... black tubed and bought somewhere between 2006-8, a wonderful scope. I wondered why Astronomics didn't call these new AT80ED AT80EDII to differentiate them?

 

Given the new ones are white would it then just be simpler to say original = black tube, new model = white tube ... or where there ever white tubed older versions?

Thanks for the pic!  Do you know the weight with rings?

They would need to call it AT80ED III.    grin.gif   Here is my white tube AT80 next to AT66.  I purchased it in 2009.
