Sound baffling at a concert venue [OC]
This faceted structure that I think is sound baffling always catches my eye when I go to concerts there. The angles catch the stage light in different ways. I wonder how many others stare at this stuff.
Rehab and eventual rehoming for blue dolphin cichlid misfits
I've got a community of white-tail acei, mixed peacocks (mostly dragon/strawberry and o.b.), and yellow labs. The acei and labs are running families, and the peacocks seem to be trying. (I didn't heed the all-male recommendation. I hoped I could give a more natural environment.)
These two blue dolphin cichlids tend to get pulled into the peacocks' aggressive bouts. One has developed and sustained unilateral pop-eye, coming and going, for what seems like at least a few months. I'm finally isolating those two and starting with a mild salt treatment in hopes that eye just needed peace, time, and water params to heal on its own.
I've got them both isolated because I just intend to re-home them once Mr. Popeye is healthy. The other three families are populating the tank with their lookalikes, while these two might be getting singled out more and more.
tldr: I'm wondering if this looks like a possible pair I should try to keep together or whether they might do just fine going to a community tank at my LFS. If there's a chance they've bonded, I'll try to re-home them directly to keep them together.
Modding an Old Scope
Hi, Lemmians,
I wanted to share my experience messing with an old Dobsonian-style scope. My parents had a Coulter Odyssey 10.1" covered by a trash bag since somewhere around the early 90s. We used to have pretty dark nights back then, but the light pollution crept up over the years, and it probably went a couple of decades without any use, so they sent it with me after a visit.
It didn't take long before I was shopping for eyepieces and realizing the original focuser was a sore spot, as it was only a locking sliding tube--no knobs or gears for smooth, precise adjustment. I started thinking about what else I would change and, with their blessing, I decided to have a little fun changing it up.
Not all my changes were improvements, but it was rewarding to tear into it and put it back together with some of my own taste applied.
