Has anyone tried 6.17 or 6.18 of Maxim yet? There was a possible fix for this problem but as others have seen the problem using other software I'm doubtful, but we still need to confirm it. I've just been really busy lately and have not had a chance to install the demo and test. Thankfully I have an Orion SSAG on a guide scope as well on my imaging setup or I would be pretty much dead in the water. I have the STi on the SBIG OAG, I specifically bought it to get rid of flexure to enable me to do longer exposures for narrowband, but the bad subs don't allow that. In the winter I've had some success using the STi, also using the smallest track box size seems to help reduce the mount jumping some. It is quite frustrating to have invested a large sum of money in the OAG and STi a few years back and STILL can't make use of it. I'd like to just get a different guide camera but I don't feel right selling the STi to get funds to replace it knowing it can't be used. The staff says they can't reproduce the problem in house, with this many of us having the problem I hope they see the need to concentrate some more on this.
