Orion ED80 used a 100mm tube though. Which makes it a little bulkier. 

I had the Orion 100mm f/6 scope. Yes it did use the same tube & weight about the same as Orion's 80mm f/7.5 ED. But the AT80 f/7 still sounds promising. I wonder if any AT88 or AT90 in the future using the same kind of glass?

I have a feeling Astronomics will sell a lot of these...  waytogo.gif

There won’t be one in between as it would just get things to confused size wise.

The thought is solid, but it is too small a step. I do however appreciate the input.

So would i need a 80 AT if i already have a 90mm W/O F6.2?

Probably not unless you find the WO to be "chunkier" than you'd like. Is the WO a triplet? If so, it might acclimate a little slower but in your area that's probably not an issue.

It is a 2 element lens. It is heavy, but a LX70 holds it fine and i already a 72mm SW ED. But i like trying new stuff for kicks.

Me too. I do see this 80 as a solution to a desire for a good gng for not too much $. I want to keep my Oracle pristine and my 102A while very nice on my SP mount, is not quite as maneuverable as this 80 would be on a small alt-az.

Is the length with lens shade extended and retracted know yet? This sounds like a very attractive acquisition.

I imagine the SV Access is a good guide on that.  The 80 Access is 18” retracted and 20.5” extended.

If you order online the computer will authorize the full amount, not much we can do about that as it is a function of the credit card company.  If you call in an order we don't charge until the scopes have cleared customs.

Hmmm, that sounds like an awfully short dew shield. When retracted, is the front of the shield just ahead of the objective?

Just a little.  I will check later.

Those are definitely the specs SV gives. Just curious . . .

I wonder what those specs are for the AT 80ED.

My guess is that the OTA will be essentially the same but the AT version is using FK-61 whereas the SV version uses FCD100.

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? The Lunt comes with a case, but the Astro-Tech comes with a nice diagonal and better tube rings and dovetail. THe focuser appears different, but both appear to be made by Kunming. The AT will be $50 less and have nicer mechanicals as well

I suspect it will be very similar to the SV80A as far as build goes. I would have jumped on one of these if I knew they were coming out but I just picked up a SV80A. Comparing it to my AT102ED it seems the focuser, tube rings and quality of the fit and finish is the same. One is matte finish the other is glossy. That makes the AT 80ED quite a bargain if you ask me. Here's a side by side photo of the 2. 

 

The SV80A has a 5-1/8" dew shield but only overhangs the front objective by 3-1/4". The size with the dew shield retracted is actually 18-5/8" with the 1/1/4" adapter installed but no diagonal. 21-1/4" with the dew shield extended.

 

I didn't see anything in the AT80ED description that mentions it coming with a diagonal. The AT102ED didn't. I don't know what kind of focuser is on the Lunt but the one on my AT102ED very smooth and precise. For $399 this is a fantastic deal. 

SV80 & AT102ED

Ah I think they edited the description. I could have sworn that it said it came with one the other day

It says...

An optional Astro-Tech 2" dielectric star diagonal #AT2D will give you the same 99% reflectivity performance with 2" eyepieces.

I am suddenly thinking this would make a GREAT birthday present! I might have to start dropping some major hints to my husband...

 

 

I'm told (repeatedly) that hints don't work on males.  Tell him straight up.  wink.gif

My wife and I raised 4 daughters so I've managed to attain what for men would be the equivalent of a PhD in hint reading.   Unfortunately, by the standards women have for hint reading that amounts to the equivalent of a 6th grade education.  :)
