I can answer some of the questions about this scope being asked here.
I've seen the AWB C80's come in and out of availability. My *guess* is that Celestron has made available to them a pretty sizeable supply at a fantastic price, but they don't want to order too much (probably for reasons relating to tying up meager capital). So they order say 20, then when they run out they order 20 more...
Celestron is a big supporter of AWB, and when 25 of these were found in their warehouse they donated them to us. There's no capital for us to put up -- we just sell them and notify Celestron to drop-ship them. After those sold they found some more so they gave those to us, too. That's happened several times so every time we thought this well had gone dry we've ended up with more. That's why the site would show them as gone and then it would come back. We thought all the remaining stock was gone. Actually, there were a few times we knew there was more but they had transferred a limited number to stock so we had to wait for that to be replenished. Maybe we should nickname this scope "Phoenix."
They don't know why they weren't blown out by Celestron years ago when the scope was discontinued but that's worked to our advantage.
This is pure donation -- we don't pay anything for them. When you buy one of these scopes every penny goes to support AWB's worldwide astronomy programs. Celestron even donates the shipping to the US and Canada. As well as their labor to do this.
Of course nobody knows how well stocked the Celestron larder is. We do know that the scope is no longer made, so at some point (whether tomorrow or two years from now) they'll run out for real.
There are around 60 or 70 of them available now. Celestron usually transfers 25 at a time to stock so if the site shows them as being out of stock it will only be a couple days before there are more available. Until they're gone. Celestron says this is the last of them, and I think this time that's really the case. This is kind of a sleeper most of the time with people not knowing about it, but when there's a Cloudynights thread or some other mention online the orders start coming in. So there's no way to know how long these will last but there are several orders per week at the moment.
For those who mentioned that they never heard anything more after being notified about the scope shipping, that's because Celestron ships them and sometimes we have trouble getting a tracking number from them before the scope is delivered. They're doing us a huge favor so we can't be pushy. But if there's every any issue or question just drop us a line at firstname.lastname@example.org and we'll get answers to you.
