Hi Ralph, I have a QSI 532ws with standard 1.25" Astrodon filters on a 16N/Wynn 3". One corner of the frame shows vignetting with this smaller chip and the focal distance is smaller than the wsg version so I would recommend the 31mm filters Bob is using. Flats remove the slight vignetting. There is, I think, a small problem with the corrector and high precision flats which I am trying to track down. More on this when I pin it down and discuss it with Phillip. Bill

Hi Dale, Mostly cloudy here since the 1st of June so no chance to thoroughly test the work-around from Bob Denny. It seems to work ok but I am learning not to trust anything when operating remotely. Are you using ACP Scheduler? Happy? Bill

I have had similar problems depending on the order in which ASCOM, AutoSlew, and ACP are installed. Installing ASCOM last as Administrator seemed to work most of the time on Win 7 64bit machines. Bill

I'm having USB communications problems with the hub port on my DDM85. Everything seems to be ok until I start taking multiple images in succession and then the dreaded 'software unplug' event occurs which, if I am using ACP to control the session, aborts the session script. I am using 5m active USB cable extenders on both the Com (mount) port and on the Hub port. It's the hub that always falls over. I have tried a USB/Ethernet (Cat5) extender but it does not want to connect to the camera and focuser through the hub. Does anyone have a working configuration with a 5m separation between the mount and pc? Bill

Hi Philipp, Bob Denny came with a work-around which turns the tracking back on before ACP tries to Park the scope during shutdown. This will work until the next release however, another little twist has emerged: When ACP Parks the scope from shutdown with the tracking on it now goes to Park 2 rather than Park 1. What is the ASCOM Telescope.Park method supposed to do with Park 1 and Park 2. I had always assumed that an external Park command to AutoSlew only works with Park 1. This is not a serious problem for my remote observatory since I have now set Park 1 and 2 to be the same but it is very curious. Bill

I have a DDM85/16N system that I am commissioning. A serious control issue between ACP and AutoSlew has emerged with respect to the Telescope.Park method used in ACP. AutoSlew apparently sets the AtPark property to True when the tracking is turned off even if the scope is not parked. This means that ACP does cannot park the telescope first during a shutdown (since it says it is parked after the tracking is stopped) which means I cannot close the roll-off roof - it does not clear the telescope unless it is parked. I have had a remote session with Bob Denny that demonstrates this behaviour of AutoSlew. Mr Keller please advise. Bill Martin
