Took a look at the Owners Manual in the
Download section, and it states it can be mounted either upright or upside down. Another plus is it shows on the Spec sheet, the PFA730 Base is included with the camera. This would be a reasonable choice for a camera that doubles for use as a sky cam or weather cam as it virtually has no limitation with how high it can be pointed so long as nothing is in the way, like an eave. Specs are almost identical to the SD49225, with added intelligence like autotracking. I sent Andy a PM, but haven't heard back yet, on price.
