Great pic. I can see Alcor easily in your second pic, but not in the first. Is the big dipper there?

Nope, dipper is only in the bottom pic. I just saw it down there during ISS flyby, and decided why not try and get a pic. I was pretty impressed, dipper pic was first shot, no editing.

ISS pic is 2 30sec shots merged to one, but no other correction.
 
Bicycle fast food delivery to the ISS. It's the next X-Prize project.

Not the ISS, but we have a weird halo around the moon tonight. I took a pic. 15s exposure. A plane with a blinking light went by during.

Cool pic.

I've seen this halo effect before with the sun, but don't seem to recall the rainbow phenomenon your pic seems to show - is that real?

It just looks white to the naked eye, but just like a rainbow I suspect the light spectrum is getting spread and the camera is seeing the colors. I was just out there (with neighbor) and it's still up there.

That halo is caused by ice particles in the upper atmosphere reflecting & refracting moonlight. Same phenomena, it's just that moonlight isn't as bright, so the rainbow effect is muted.

Sky Guide.

I bought this to help me look at the stars at night. It's pretty spectacular. You can look around in your house, then walk outside to see the real thing. You have to see it to believe it.

Tonight, I went out to look at the ISS going overhead and was flabbergasted to see it also racing across my Sky Guide screen. Turns out, Sky Guide has a $2 add-on that you can add that identifies all the satellites in the sky - I hadn't paid for this add-in, which is why is says "satellite" instead of ISS in the screenshot below. By "satellites", they mean the ISS, jettisoned space debris, Iridium and other comm satellites. Click on one of them for more information about the thing than you care to know. E.g., I just learned, after clicking on an Iridium satellite, that a new set of 77 Iridium satellites will be launched starting this year to significantly improve space-based satellite phone quality. I thought it was dead.

You can zoom in the normal 2-finger way, look "through the earth", search for stuff (e.g., click the magnifying glass, type in big dipper, and you'll see an arrow appear on the screen; just keeping turning, following the arrow, and bam there's your object). It also will give you notifications when astronomical events are going to happen (don't miss the next ISS passing or asteroid).

Very cool. Search and buy Sky Guide. I did not compare this to any other apps, but I saw my brother in California using it and bought.

Haha, if that's real, then that's not a good sign for any near-term success.

Oh no. It's real. Musk joked about it. Platform was only nominally charred. I didn't read the latest article but they believe if they put more fuel in it the additional weight will stabilize it.

Kinda sorry I didn't think of watching the ISS tonight. Was out xcountry skiing in 4' of snow and -3 degree weather.

Found some pics on the surface of venus with some 3D radar mapping of the surface. Pics from Venera up to 13. They say Venus' atmosphere absorbs the blue spectrum. Some claims about lying about surface temps & pressure too. Enjoy the hilarity of some folks...

Nice pics though, & the only actual pics of the surface.

The russians have sent a bunch of missions to Venus. They've been focused in that direction, the U.S. in the other.

Venus has been very bright in the western sky lately, just after sunset. Mars has been right above it, and Jupiter in the east. Good stargazing in my area lately.
 
Early risers will see a full lunar eclipse in the AM. It's best for west US, where the full eclipse in the western sky won't be interrupted by sunrise, which is what I have to deal with here. I do have the advantage of living on the west coast of FL, so I can watch over the gulf of mexico.

Will look something like this (maybe!). Moon passes through the shadow cast by Earth. Red wavelengths refract into the umbra (shadow) and create the "blood moon".

I've a horrible cold and haven't slept much consistently the past few days. If I'm up, I'll check it out, but not really planning on it this time....especially since I took these last time :)
