Who Are We?
Patrick Sutton's outstanding 8" Dob: solid mount, clamshell rings, altitude bearings, tube end rings. Thank you Patrick!

"Mark worked tirelessly with me on my mount project. I had many ideas for customization and changes that I wanted to make and he worked with me on every single aspect of it. He would not rest until I was satisfied and his attention to detail and commitment to his customers is truly amazing. Thank you again for everything you did, Mark. I am truly grateful and very happy with my mount

"I just finished installing 3/4" wide by 1/16" thick white felt. The clam shell closes completely now, and the tension seems about right. The telescope tube can be rotated with a little effort, but not too easily. The hose clamp is probably not needed, but I am going to leave it on for now. I have been using the telescope and it gives very nice views of Saturn at 175X from my light polluted back yard. It does a good job on the brighter M objects, and the Moon is outstanding!. Thank you for all your help with this project. I am happy to recommend your products and services.
