I have obtained permission from AAVSO to post this
I have the above filter that I purchased last December (2013). For reasons, I need to get rid of it. I have never used it, never plugged it in, or anything like that, and so it is completely new. Daystar just informed me that the 10 year warranty is transferable. You can buy it for $3600, you pay the shipping. It regularly sells for $4800. It comes in a Pelican case and has all the other parts that came with it (power supply, electrical plug in's such as wall socket plug, etc.). I also need to unload the following items, or try to return them to the vendor they came from:
Televue Powermate 4X - $330
Astronomic ERF - $104.50
Daystar Solar Finder - $35
So that you will know who I am, my web site is at http://users.commspeed.net/stanlep/homepagens.html 
It has not been updated for a long time. I have gotten more deeply into spectroscopy since I created it and have a paper in the Journal of the AAVSO on the spectroscopy of Epsilon Aurigae.
