Another example of insects using polarized light to navigate, as do honeybees . . . pretty cool dung!


One of my biology colleagues at work is an entomologist and a bee expert. He's out of grad school not more than 5 years. Says he was taught that insect eyes could not make use of starlight. Bees of course use the sun. As Mike points out since its the polarization that their eyes are sensitive to, starlight will do just fine. Resolution is not important. This is groundbreaking work.

Anybody notice that 12" LX90 ACF GPS for $1500 on the local CL?

I asked about it, and the seller said it's NIB, just lacking the tripod.

I'd be all over that, but it's not much of an upgrade to my NS11 to go through all the gyrations of a new scope and such. I also hear the 12" might be a bit undermounted. Still not a bad deal for a nice 12" GOTO.

Dung Beetles are astronomers too and they do it without Goto.

Is it any surprise then that early humans could find their way across the globe?

Good stuff. Pretty amazing.

Now why do I feel the need to start quoting juvenile poetry written on restroom walls? :grin:

Thanks Stacy! The "landscape" was out on the North end of Camano Island...
The moon was shot through my AT6RC last night. I've been trying to mount it up more often. The last time out with it for an imaging series, the focus shifted due to the severe tempurature drop while imaging. it was very disapointing...

We had some clear patches last night. I was exhausted after last week at work but it felt good to peek at the Orion Nebula, the Pleiades, Jupiter and the Moon through binocs. Just looking up was therapy.

Thanks for the well wishes, Gang! I had a great day. I spent it out on the Cedar River doing habitat restoration work - one of my true passions. Came home a had a great dinner and drinks with friends. Couldn't have been better. :D

Now, if I could just entice you to travel to Montana! :lol:

Oh BTW, count me in on pixieland and any other SP at Mike's astro paradise. Hold the wind though. While it was exciting, it was hard on the shelters:-)

Ha, thats puting it lightly. I can't wait to see everyone this year.

I'm sure it's toasty and warm at "Den Mama's" place :ubetcha: Besides, they don't call it "Big Sky" for nothin!!!

Yep, the Den Mama's place has been nice! Couple of days ago, low 50's! Outside of one major blizzard early in the season, it's been a mild winter here, with gorgeous night skies. So come on guys, hogtie Pegs, and all come on over! :grin:

BTW; any of you PNW members here, if you ever get in my area, please feel free to drop by & spend some time under the Big Sky Country, looking thru my 16"! The very first views I had of Pluto & Ceres is when Pegster visited & found them. What a thrill it was to actually see them!

I would love to see some nice clear winter skies above 40*. It has been so miserable at my house because even the few clear nights we had, there was thin fog that froze your objectives within 15 minutes or so. I have just had some quick binocular trips until I can't see anymore from the ice, then back in the house. This is why I am thinking about getting some decent binos.

How is this winter in your areas? Have you had any good nights or just astro fixes?

Carol, I predict that I'll take you up on that; I drive to and from SW North Dakota from time to time and even get off the fwy. occasionally to go through Helena. :)

Sean, my area is just like yours, except I think I got in a few more hours with binos than you did. Like most here in Western Washington, I live close enough to salt water to be blessed by that marine-inspired fog and overcast we see too much of this time of year.

I bathed Sugaree's primary a couple of weekends ago and I'm itching to check it out under the stars. One piece of maintenance I need to attend to: there's something wrong with altitude on my ArgoNav . . . encoder or cable or something. I phoned Eric Webster about it and he gave me a couple of things to check out. He also said if I came up empty or confused to call him and he'd walk me through it over the phone.

Mike, I'd enjoy meeting you in person, and spending some great time at the scope!

Mike, are you still liking your 12x36 IS binos? Have you noticed any breakdown of star images at the edges? I have been reading reviews and am trying to gauge if the reports are just something barely noticeable or what the reality is. I have been able to narrow down to either 12x36, 15x50 or maybe 10x42. The latter is the least likely because I believe that I can hold 10x reasonably steady. Anyway, your opinion on the 12x36 would be more helpful than reading more reviews.

Sean, my impression of the 12 X 36 IS is totally positive. I too am (or at least *was*) sure I could hold lower mag binocs steady, although in my case the lower mags are 8Xs, not 10X. The much higher mag IS binocs made it clear to me that what I thought was "holding steady" really wasn't. This realization hit me the first night, when I could see two sets of doubles with the IS that I couldn't see with the 8xs. The difficulty with the 8xs wasn't that the doubles were too tight (although tight they were), but that tiny hand motion subtly jiggled and smeared the image, just enough. (I can't be totally sure of this without trying the same view with 8X IS, but I don't have any. I'm reasonably certain, however.)

My pair is well-corrected to the edge. Honestly, I haven't looked through them critically to determine what percentage of the total FOV is degraded; I simply haven't noticed any such problem. Also I've used them during the day for some casual birdwatching. At the percussion retreat 3 weekends ago I went down to the dock and checked out swimming birds at various distances. I was really amazed to recognize a pair of mystery ducks' yellow eyes at a range of ~ 175 yd., which allowed me to later identify the pair as Barrow's Goldeneyes.

I chose my binocs after receiving feedback in a post here, which might be a place to start. Note the reference in it to Gary Seronik's IS comparisons on his website. I decided I wouldn't spend $1200 for the pair I really lusted after, but I'm very happy with what I bought for about half the price.

Sean, if you get the 12X36 make sure you get the more recent model. They are remarkably light. I love my pair but I don't use them for astronomy so I can't speak about image degradation at the edges for night viewing. I use them to watch ships and birds in the Port Townsend area and they are marvelous. I tend to only look in the middle of the field anyway. If something near the edge catches my attention, I simply swing over to it. The IS works very well.

I forget where you live. My binoculars are in Coupeville right now but I can retrieve them on my next trip and lend them to you if you are near Kirkland. It would be after Feb 10th before I could get them, though.

You guys are convincing me. I was pretty sure that it was a case of the minor problem being mentioned at all making it sound worse than it is, I just had to double check with someone who's opinion I trust. Thanks guys!
