Hi!
I have a few questions re additional information on the OTA you are offering:
1. Did you purchase the OTA new?
2. How old is the OTA?
3. Will it come with the original fit finder, diagonal & adapter?
4. Have you had any issues recollimating when going back from the hyperstar setup to standard configuration?
5. Any issues with dust ingress as a result of changing configurations?

Thanks in advance for your time,
Mark
