  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Calgary Area Meetup is set for Saturday July 12th at 10am. The signup thread is here!

    Spade connector question

    I bought a kit off Amazon a few years ago. The metal is so soft that even with a full crimp the wires will pull out. I ended up cutting off the shrink tubes, soldering the wires in and new tubes.

    Rain in Edmonton

    We see similar in Fort Erie. Rains in Niagara Falls a fair bit and nothing to the south. The winter it is all reversed. We get dumped with lots of snow and nothing except green grass even before you get half way to Niagara Falls

    Telescope secondary mirror support system

    Test assembly of the support system. You can see the three mirror clips now. Need a few adjustments to the lengths of the whiffletrees posts and a few little clearance issues that some file work will fix up. Good day so far! Pierre

    I forgot to mention that these clips do not touch the mirror! They are there just incase of stupo stuff!

    Telescope secondary mirror support system

    Yes I am on cloudynights. Been there a long time now. I will be posting a full build thread at the end. Today’s job is printing and adding the mirror clips to the whiffletrees.
