Looks good. I'm going to order one soon as I check my tablet to make sure the app works on it. I'm sure it will it's a Samsung but I need to dig it out to be sure. Soon as I get back from the Mayo clinic next week, did notice it's $50 more on Amazon compared to order it from Astronomics, the only other place I looked. Too bad I didn't have an appointment earlier when they were really having the northern lights. I saw them in AK but they were pretty tame while I was there.

i want seestar to make something bigger with a better sensor
the sensor is only 2 MP for 500 bucks it is great for what it does.

i would like it to be upgraded to a larger size for the sensor and the aperture.

say in the 12 MP or higher for the sensor and if the aperture was offered at say 80 107 or 130 mm
would be a killer item imo, depending on how much it was.

One of you guys give me a response for this dude for why the water isn't free floating out of that glass? The retarded comment about force has already been dunked hard.

"“Water molecules like to stick to glass and also to other water molecules more than they like to disperse in the air,” Jordan Bimm, a postdoctoral researcher and space historian at the University of Chicago, told the AP. “So if there is no external force, water remains in ‘clumps’ in the weightless environment, and in this case inside the glass.”

He added that surface tension — a property of a liquid’s surface that helps define its shape and allows it to resist external forces — “also works to help maintain the static shape and presents the illusion of how water would act on the ground.”

A separate video posted on Weibo, a social media platform popular in China, in June 2022 by China’s manned space program shows behind-the-scenes footage of the Shenzhou-13 crew preparing for their livestream lesson by carefully pouring water into the glass through a straw so that it stays in place. It also clearly shows strips adhering the glass to the table."

When he's so thoroughly stupefied, why do you need more proof? Why are you still reading these fucking people and subjecting us to their retardation. Your schtick with this shit is getting thin when it spills over from the other threads where we are prepared for that idiocy, if we so choose to read it.

Also, I guess he has never had a drink in a car or an airplane, not to mention the speed we are all moving around the sun, which is in turn, moving around the galactic center, which is in turn moving around the center of gravity of our local cluster, which is in turn moving around the center of the super cluster, which is in turn moving...

Rumors are swirling after two former giants in the astronomy industry closed their doors earlier this week. Pretty sure Orion is just an importer that specifies stuff and brands them their own.

I don't know, cloudynights.com forum has locked all discussion on the topic, but who knows they are owned by astronomics. I know Orion has issues as of late and Meade since their lawsuit.

ZWO is having a sale. Their seestar s50 down to $449 from $499.

Extremely interesting

Had dinner with my cousin from SpaceX the other night. Seems like Musk's threat to move the headquarters to Texas from CA is mostly hot air and will just entail changing the address on the corporate paperwork. No offices, employees, equipment, etc, are being relocated.

He had some details on the precise failure of the booster they lost a few weeks ago. Apparently there was either a loose clamp or some compressed insulation that allowed a pipe to vibrate and suffer a joint/seal failure. This pipe carried liquid oxygen to a sensor measuring pressure in an engine component. The leaking pipe exhausted liquid oxygen over an adjacent pipe, causing its contents to freeze. This second pipe carried some kind of ignition accelerant compound to the engine, so when they went to re-light the stage for the return burn the flow was blocked and they ended up with an excess of methox in the engine bell. Eventually the clog melted and the igniter arrived, but at that point there was too much reactant and everything exploded. Oops.

Apparently the solution that satisfied the FAA was simply to remove the pressure sensor.

JPL and Vandenburg military base where they do launches from are there, so makes no sense to relocate (especially since they do many military contracts).
