Although this is a post from a year and a half ago, I can now reply.
I purchased the Alcor-system.com's Alphea 6CL in October, and yes it is expensive.
As background, I have previously used StarLight Xpress' Oculus all sky camera with their software and with the free AllSkyEye software developed by Michael Poelzl.
I am in the middle of writing an experience article for cloudynights describing the installation and use of the Alphea.
Things to know before buying:
- The camera enclosure and connectors are ruggedized. Better than Oculus.
- The manual is very incomplete.
- User interface takes a lot of getting used to.
- There is no user support forum
- Support is only through a very busy developer who has little patience.
- There is a licensing method that ties the Alphea/ZWO serial number to the SkyWatch software - which has failed twice on me causing lots of lost time.
- I estimate that the free AllSkyEye software implements most all of what SkyWatch software has. An important difference is that with the AllSkyEye software the star and constellation overlay is not completed but I'd expect this would be remedied with a future release.
I can go on, and I will, when I finish my article which in now 7 pages long. I attached an image obtained last night (SQM=19.5) that shows the star overlay. No doubt that is cool. I live is suburban southern california and our weather has not been very cooperative. On a good early morning I will get an SQM=20.5
