Hi Doug, Thank you for solving my filter-wheel problem. I have another question I hope you can answer: I will be using my new STF-8300 Pro Package at dark sites, far from electrical lines. When I used my old ST-402 I ran it from a rechargeable motorcycle battery, which worked well. The new equipment didn't come with a battery adapter, and I am wondering, first, will the old one work without damaging the STF-8300?, and second, even if it will, where can I buy the correct adapter (the old one is somewhat frazzled)? I appreciate your help -- Joe
Yes the cable is compatible. You can buy a new one at: http://diffractionlimited.com/product/12vdc-battery-cable/
