It's about 7 PM here in the Midwest so I started connecting all the equipment on two separate SGP windows. So Far I was able to get both cameras cooling and able to connect to the mount. FWs and focusers all connected successfully.
I will be using guiding with the longer f/l scope, but not the shorter f/l scope. Where the rub may come in is with the two separate models for the scopes and the 10 Micron mount. What I hope is that the model for the shorter f/l scope will work with the longer f/l scope. The shorter scope will run unguided and definitely needs the model for 30 min nb subs. Supposedly, with guiding, the model for my bigger scope is not as important. Where I can see a potential problem, is the pointing accuracy and auto centering using the shorter f/l model. Cameras will both have to be cooled at the same time, unless I want to cool at the sequence start and waste a 30 minute exposure once the tandem scope begins its sequence.
I've also set the two sequences such that the first camera has time to warm up and then shuts down the sequence with a 15 minute time delay before starting the 2nd camera run of SGP.
All a big experiment for now, so stay tuned and see what happens with this adventure............Gunny
