  1. Lead Acid Batteries 101

    by , 10-03-2017 at 02:55 AM (Dee Fitz's DIY Conversation Corner)
    This is from a recent thread I replied to a while back.

    I've long been an electric bicycle aficionado and I have a good friend who is the local Solar Power Guru where I grew up, and, well, the electrical efficiency engineer at a local municipal power company in Muscatine, IA. He and I had so many talks about batteries, I became quite knowledgeable myself regarding the "battery conversation" as he and I called it.

    Once I got into using a telescope, and while ...

    Bortle 6 to 7 skies: 6 if you’re looking in the right (dark) direction, west and zenith mainly. Looking North towards FoCo, or southeast towards Loveland, CO and I think you get Bortle 7.
  3. Deep Sky This Month - October 2017 (Northern)

    by , 09-30-2017 at 07:16 AM
    Howdy folks and welcome to October. This time of year can often provide some excellent opportunities for us northerners, though some of our friends in southern hemisphere may be starting to experience unstable weather as they move deeper into spring. There are some excellent opportunities to pursue my favorite objects – galaxies. Therefore our focus in this month’s edition will indeed be those distant star islands that fill the observable universe. Galaxies are overwhelmingly the most prolific ...

  5. M33 on a dewey night - this is ugly!

    by , 09-21-2017 at 01:11 AM

    It was not horribly warm last Saturday, and I have been itching to improve on my M33 from last year, so I planned to get much more data on it than I did last year.
