I am offering my Baader Semi-APO filter for sale. I purchased this filter for use on the IStar 127mm f12 refractor I was building, however the f12 had very little CA and this filter was not required. It was only used a few times and is in its original box as shown it the photo. No marks on the filter rim or lense element.
Current new price locally is around $119. I am offering my like new Semi-APO filter here for $75 postage included to aywhere in Australia.
This filter will be useful to anyone with an Achromatic refractor, the write up on this filter is attached here:

If your interested in this nice filter please PM me here on IIS.
Thanks for looking.
