Step 1 Pick a single character you want to use for this series of Thursday events who has access to their personal starship. You only get the mail with the special MCR-100 pet if you scan all the Imperial droids with the same character. On shared planets like Nar Shaddaa do not scan the droids in Republic areas with your Imperial characters or you may not get the pet. We'll finish off the Rep droids in the final week with Rep characters.
Step 2 If you don't have them already then grab your Macrobinoculars from T4-M7 (screenshot) on Imperial Fleet (map). In the final week when we're on Rep side you get them from M3-8Z at Rep Fleet.
