Rich, I just bought a wyorock focuser a couple of weeks ago. Carolyn was very prompt in her replies to me. They even machined a custom base to fit my tube OD. This is my third wyorock, I love them. Did you use: wyorock@comcast.net ? Also, she has one listed on eBay right now: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=160469922573&ru=http%3A%2... Search for item 160469922573 if the link doesn't work. Only one day left on the auction, so hurry. You might want to consider a 2-speed focuser for that fast mirror, however. Your "sweet spot" for focus is very shallow and a reduction focuser would allow you to hit it much easier. My usual cutoff line for a single-speed focuser is f/5, although the wyoroc is so well-made that I use it on one f/4.54. On 8/19/10, Richard Tenney <retenney@yahoo.com> wrote:
Will likely go with a Wyorock focuser (if I can get them to answer their e-mails!),
