Looks like an Astrotech 80mm f/7 ED will be available at some point.

Nice!  Here's hoping it is lightweight with a simple, effective and reliable focuser and good optics.

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

A friend of mine from the club has an AT-80 and loves it. I have an AT-115 and I love mine more! I am sure you will love your's!

Sounds nice; hits these good spots for me for a quick look refractor:
ED Doublet @ f7
Sliding Dew Shield
Rings & Dove plate
Two speed R&P focuser
NON ROTATING FOCUSER (simpler, lighter,less fiddly)
No extra economy accessories.
I'm game 😉

This is awesome, an 80 mm ED for $399 shipped.  This is something that has been missing from the market for quite sometime.

FYI, website has conflicting focuser info. It says crayford in one spot and R&P at another.

Probably not.  Too long for the market in general and shipping would be a nightmare at f/12.

The OTA & tube rings weigh a hefty 9.1 lbs. That would put a strain on my Celestron

AZ-3 mount with load capacity of 10 lbs.

How about a 152 f-8? doublet?

Yea, I thought that too when he posted it. I'm not very knowledgeable about glasses. What would it take to have good correction at f9?

It will be much lighter than that.  It is lifted copy from another instrument.

I would think you might have to approach f/9 in a scope of that size and a doublet.  I could be wrong however as the f/7 models have all worked very well.

I agree—this is something I have been hoping to find.

Orion 80mm f/7.5 ED weights 5.7 lbs.without the rings which should be few ounces more.

$400? I thought the original in 2008 was a good deal at $500+.

 

On a gem I like the rotational focuser on the original model, but today with a lot of Alt Az mounts in use that's less of an issue. Plus with split ring mounting on the new model you can just as easily rotate the scope as required.

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

Do I need an 80mm scope after my hate for the ST80 because of lack of aperture, no. Do I want an Astro Tech scope because I’ve always wanted an Astro tech scope, yes. Do I want a new mount and eyepieces that I’m saving for, yes. Does this 80mm f/7 override those right now, yes.

It’s the same ED glass as in the AT102ED (per astronomics site) which is good enough, considering the price. Too bad there’s no picture yet.

Photos will be available in October when the scopes arrive.  Just think AT102, only smaller...

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