| 13.1" F4.5 Telescope for John T., Jackson MI. |
John T's 13.1" F4.5 optical tube assembly (OTA) is virtually complete. I need only attach the alt bearings and finish the rocker box. My goal is to complete the telescope by the end of this week.
Note this telescope has the "ETT" option. The Easy Transport Telescope option has 1/2 the length of the struts with a reinforcing intermediate ring to add rigidity. The struts are 51.5" long (each of the 6 smaller struts is 25.75" long for "easy transport").

Works continues . . .

| 6-point flotation mirror cell installed on mirror board (Since this is light mirror, a Baltic birch/aluminium cell works well) |
Progress continues on John T's 13.1" telescope with a Coulter mirror. The mirror and secondary has a 96% enhanced coating -- brand new. This is going to make a nice telescope!!

| Silicone has been applied to the 6-point cell. The center rear of the mirror is marked with a "donut". |

| Once the mirror cell has been applied to the mirror the silicone needs 24-hours to cure. You can see the 3.1" secondary to the lft. |

I want to thank everyone for their patience during my absence. I was traveling -- and now am back in the shop. Once I get through this crazy "jet-lag" I'll get busy. Probably this coming Saturday.
Meanwhile, I was treated to a visit from one of my customers, David and his wife Donna from Fort Worth Texas. We had a delightful visit, shared lots of interesting stories, got to know each other and enjoyed lunch together.
And, my invitation to you is simple. If you're in the Palm Springs (Palm Desert) area, I'm always available for a face-to-face!!
Any time.....
