I narrowed down observatory choices to 8ft Exploradome and Nexdome. The dome will be fully automated and will have a UPS back-up for safe shutdown in case of power outage. The observatory will be remote, 100 miles from my home, in a safe location where security is not an issue. The weather is mild but can get rough during the winter with 20-30 mph wind. There is not much rain and no snow, the coldest temps are in the 30s and the hottest Summer days are in low 80s Fahrenheit.
My main decision criteria is reliability, as I want to minimize emergency trips (200-mile round trip) in case if dome shutter fails to close. Secondary decision criteria are ease of assembly/maintenance and cost.
If you either used or compared Exploradome and Nexdome, what are your thoughts?
From my research, Exploradome has been around longer and is a bit larger dome (92" vs 88" diameter). Exploradome has recently moved to MaxDome II control system, which is supposed to increase reliability. However, Exploradome is more expensive than NexDome, close to 2x (with full automation). Key question is how much more reliable Exploradome is compared to Nexdome.
Thanks in advance for your advice.
