Various thoughts and activities related to my amateur astronomy interests including telescope making and observing. Plus other stuff that may be on my mind.

First light! I used a 2x4 as a strut to get the exact measurement between the secondary ring and the mirror box. I estimated it to be 51". Turns out it is 50 3/4". Now I just need to get the moonlight truss system and this will be done! Got to see the moon eclipse a bright star too in the scope!
Closeup of the Protostar spider and the secondary ring. You can see I used some clamps and scrap wood to attach the ring to the 2x4.
