The 20 inch Itch

I was recently diagnosed with a severe case of "telescopum aperturus
dermetitas", also known as the 20 Inch Itch. In case you are
unfamiliar with this malady, those afflicted have uncontrollable
desires for photographic access to telescopes at dark sites with
secondary mirrors at least as large as the primary mirrors of normal
Rather than face months or years of chronic suffering due to the high cost of a permanent cure, modern technology has allowed me to scratch my itch! I recently started a course of therapeutic treatments using a 20 inch f/8 RC scope via Internet access and control and am pleased to report that my condition is in remission.
