Denkmeier Binotron 27 SCT system. Essentially brand new - used only twice. The embarrassing part of this is why it is being sold. I have had a Binotron 27 for a number of years and love it on my 20-inch Newtonian. A friend building their own observatory asked me to help equip it - so I included the Binotron. Unfortunately, a C14 on a German equatorial mount inside a 2.1-m diameter (Pulsar) dome only just fits - and so trying to use the binoviewer is just plain impossible. In some positions it was possible, but overall it was just too awkward to position both the binoviewer and your head to use it comfortably. So, unfortunately, we decided that it wasn't working so needs to be sold.
This system has everything. It is the SCT Super System, which includes everything that the usual Binotron contains (extension tube, OCS, power switch, case etc.) for attaching to a Newtonian but also a special locking diagonal so that the off-axis weight of the system doesn't make it fall off. (One part screws into the rear cell of the SCT and can be locked in place, while the interface between it and the diagonal has a toothed locking mechanism so that you can easily rotate the system but then it locks solidly. See pictures and link.)

It also has the Filter Switch which allows 2 separate 2-inch filters (e.g. UHC & [O III]) to be slid into the beam.

Also, the OCS has been upgraded to the larger A45 version so if you want this for a Newtonian then it has the best OCS.

Finally, it has the LOA 21mm "Deep Immersion" eyepieces. While these are a bit of a gimmick, they do actually make observing some of the brighter targets (especially open and globular clusters) a bit more fun. Also included is a "Neutral" 21mm so you have a matched pair of ordinary eyepieces plus the LOA eyepiece for a bit of fun. As ordinary 21mm eyepieces they are very nice. (Read the reviews on the Denkmeier web page and other places so you can make your own judgement whether they are worth it.)

I am prepared to split these up provided I can sell the main binoviewer part, so if you want just the eyepieces, or just the locking SCT adaptor etc, then let me know (PM please) and I'll see what can be done.
Cost of new items in US$ is:
$1399 Binotron 27 SCT Super System (without the locking diagonal this system costs $1099, so we conclude that the SCT locking diagonal is $300)
$ 249 Filter Switch (no filters included)
$ 149 OCS A45 (when bought with the binoviewer, else $249 purchased separately)
$ 549 LOA 21mm pair of eyepieces
$ 149 LOA Neutral eyepiece
$ 100 Shipping (will almost certainly be more)
So the system landed in Australia would cost US$2595, which translates to more than AU$3800 at the current exchange rate. Add another 10% GST.
Is it worth it? If you've never viewed with a binoviewer - even a relatively cheap one works adequately - then you haven't experienced comfortable 2-eyed viewing. I originally bought a cheap system to just use on the moon and planets, but since I upgraded to the Denkmeier Binotron 27 with its power switch (3 different magnifications from one pair of eyepieces) it is permanently attached to my telescope and I would only ever switch back to a single eyepiece if I needed the extra wide field that my Nagler provides.
I need to sell these, so please make me a sensible offer (by PM please) on all or parts of this system. If I don't reply then it means your offer was too silly to contemplate, but all realistic offers will be considered.
