Nice user/review! I got one of the upgrades when they first became available, upgrading my Nighthawk achromat. I'd say my experiences are very much the same as yours, excellent images at any power.
I agree with David E. Nice review
To bad the upgrade no longer seems to be offered. Several vendors jumped on the 80mm f/6 band wagon after the success of the Nighthawk and this upgrade should in theory work with any of them.

This just in. Vic just posted on the Stellarvue Yahoo! Group that he will put the apo upgrade back on the Stellarvue.com website, so look for it soon.

This lens is just amazing.
I hope many of you enjoy it.

A good, collimated and thermally equalized Newt should show stars as points and not as fuzzy dots. If it doesn't it is probably because there is still a warm layer of air radiating from the mirror surface.
You are right, but, this scope excels in quick set up.
many times I have less than an hour to observe.
This lens arrived collimated and may need a collimation in 10 or 20 decades.
My 13" dobsonian needs collimation at least every time before observing for best results. It is a quick procedure but it simply does not match the 5 minute set up of the 80mm refractor.

$700 + the cost of the original scope which when I bought mine was $400+ taxes and shipping ,sorry thats crazy in my mind...
Hi Dave, I've not gone the apo upgrade route, but just thought I'd insert my 2 cents here. I agree with you that it's probably not a cost-effective thing to do to buy a $400 achromat with the *intention* of apo-upgrading it. However, for people that have had a nice achromat with excellent mechanics that they've enjoyed for years, and now wish to have an apo triplet, but don't wish to go through the hassle of selling their achromat (and possibly end up replacing it with a scope with a good lens but inferior mechanics), this sounds like a decent option. Also, not many decent 80mm apo triplets can be found for $750 (besides your Meade, that is). So far I've yet to hear anyone who's done this upgrade complain that they thought it was a waste of money. Obviously, this upgrade is not for everybody, but it's still nice to know that the option exists.
