• I took a few minutes to repair the electric focuser controller on Saturday. It was raining brutally during the day and evening. So I was surprised when I looked out the window at 6:05 to see stars!
  • By the time I got coat, boots etc to go out, the sky was already much brighter.

150mm Newtonian:

  • I tested the 16mm 82* eyepiece with and without an Svbony UHC filter on M42, low in the west at this point. It was faint without the UHC filter and noticeably brighter and clearer with it. 

So the UHC filter works. 

I'll be kicking up the voltage (12v?) on the focus controller and adding a speed controller. At present it's too fast for a 4mm and too slow for the 34mm.

Vacation Tuesday. Slept in today, I was awake a lot in the night. The day went fast. We went uptown for some errands. I didn't feel up to a walk.  A new focuser draw tube for the DS102 arrived. I installed it and the 2" diagonal fits well.  But the focuser body is worn; the drawtube rocks up and down. I'll install some shims or maybe some metal tape or ball bearings.  I also got some SMT electronics parts in.  Spaghetti dinner tonight.

Bought a Meade DS102 from a man in F'ton on Saturday. He brought it to MVHS for me in the morning, then the Missus and I headed down to Moncton. At the Hospice Shop, they had what looked like the same scope with an added box of eyepieces for $100 less! Turned out to be a DS2090, but still a great deal. Both were non-functional mechanically, so I disassembled and found the DS102 was put together wrong. The DS90 just needed cleaning and lubing. t doesn't look like it was ever used. Both assembled and working well mechanically. I took parts from the DS2090 to get the DS102 working. The DS90 works manually only. After watching for a decent sized refractor for years, I find 2 in 1 day. :|  Star test, they are very close in performance, but the DS102 more easily shows Polaris B.

Testing a 6" f5 reflector. Last night I was able to set up the fork assembly on a stool to use it.  Observations: The focuser is very fussy; probably because using a slow focuser in a fast scope.  Plywood forks tend to 'ring' from any movement. This results in a lot of jiggling. MDF would be a better choice of material. Tapered geometry would help. Buttresses would increase stiffness. Star images are 'splattered,' with no clear coma or diffraction spikes; may be combination of curved vanes and collimation error. At 188x stars show as pale round blobs, not pinpoint; this would be the result of the spherical mirror. Overall, the design is good for wide views, like nebulae etc. Planetary detail and star resolution would have limited usefulness.  I'll shorten the height of the forks later to reduce vibration. Tripod thoughts.  I will also be plagued with vibration issues in the tripod legs. MDF is not a good option. A possible solution is to extend the center post ...
