on Saturday I had the babyQ with FLI and OAG running through maxim, guiding the lodestar on PHD. Meanwhile I had cooled DSLR on APT with the FS 60 and on Nebulosity had my QHY8pro with camera lens doing its thing. I have also run two DSLRs with different instances of APT before. If you watch the cables and stagger down loads it seems ok.
In my view its maximising sky time as I only seem to get out once a month now.
