Hello everyone and thanks for the posts.
First of all, the editor from Astrophotoinsight has now agreed to put my STX report into the public domain, so you can get it on the home page of the magazine now.
Marcus - differential guiding was not available in this beta unit, so it was all self-guided. This is a good thing about the SBIG STX - they have retained that second CCD.
Jase - Precise Parts did manufacture a custom adapter for me that screws right on to the FSQ OTA - 4" in diameter. I can send you a pic if you wish.
Alex - the STX/CFW combined weight is 10lbs, the STL with its 8 position filter wheel is probably 6-7 pounds or so - I have not weighed it.
Alas, while I LOVE this camera, I cant afford one because I have the FLI Proline 16803 and have just purchased over $3k's worth of Astrodon 50mm square filters for it. So it has to go back after Christmas.
Thanks again for the comments.
cheers
Martin
