Post subject: | 28" Scope Build | ||||
Hi All, I’m building a 28” F3.65 scope using parts and advice from Webster Telescopes. Thought I’d share a few pictures of the story so far. I’ll update the pics as the build progresses. Any comments or questions would be great! I started by getting lucky and finding a brand new Steve Kennedy mirror set. The mirror was made a few years back and had been through two owners, but never put in a scope! I decided to buy a bunch of components from Webster. I’ve also relied on the good will of Eric Webster who has provided great advice and even some dimensions on the mirror box and UTA of their scopes. So far I’ve learned that building a scope is a whole lot of fun, but man, it takes a ton of time! Next time around, maybe I’ll buy….just dreaming her, but maybe give in to the blissful insanity of a 40”?!? Regards, Mark

The mirror box in the rocker box. Did this both to test the fit and to find the center point on the altitude axis (for the altitude encoder). I used a method found on the ServoCAT yahoo group. It consisted of shining a red laser on the altitude bearing and finding the location where the laser dot did not move relative to the altitude bearing when moving the mirror box in the altitude axis. The Webster altitude bearings look nice anodized black!

Wow! Looks really awesome. Sturdy & solid. I hope it's not too big to get up the basement stairs & out the door. LOL! ;) I enjoy working with wood, but have'nt picked-up a project in many years. Maybe I should make a Cats-perch chair, or something? I think the only thing stopping me is I already have too many hobbies. Life's too short & this silly work-thing gets in the way. Hopefully that will change with next week's lottery! -David. |

Thanks for all the encouragement! Thankfully I have double doors exiting my basement, so the scope is not forever trapped! Follows are some more photos
