I saw a documentary on the Saturn V computer (Possibly YT), showing all the work by women threading impossibly fine wire through the ferrite cores (I'm old enough to remember core store), and feeling angry and depressed that all that effort would be thrown away, ending up at the bottom of the Atlantic. Hopefully the days of chuck-it-away will soon be over.

Mutterings that I've heard talk about another launch in August. Booster 9 and Ship 26 are pretty much ready. SpaceX will learn a lot from this test.
-
SpaceX have a production line of Boosters and Ships. Booster 9 and Ship 26 are waiting in the wings, with Booster 10 and Ships 27-30 in production. Ship 25 is complete and waiting but may not fly at this time.

But a realistic one.

Elon said that getting off the pad and past the tower would be a success. The Orbital launch platform is still in one piece, so success.
-
Trying again.

How big Is the universe?

March 2021 6 sessions, March 2022 8 sessions, March 2023 0 sessions, and I can see April going the same way, then it's May and the end of astronomical darkness. I wonder why I bother.

There's no point. It doesn't matter how advanced the equipment becomes global warming just means ever increasing cloud cover. I think there's no longer any future in astronomy from this vile swamp of a country.

Yep, a pressurisation issue.

Here's the SpaceX YT

Livestream is live.
-
They're having to thread a very tight needle through the Caribbean, the MSIB and NOTAMs have been issued for a few days now.
-
I think the launch widow opens at 7.00 CDT which is 13.00 BST.
-
The FAA has issued the licence for the first orbital launch on Monday 17th . Will likely be at a civilised time over here.
-
The launch went OK, though there was a nail-biting delay until telemetry was established.
-
Yes, I was following the ESA livestream until they scrubbed. The thing to take away from this is the urgent need for more powerful engines.

Uncooled vs cooled (now vs Christmas) need persuading.
DaveS replied to SmokeyJoe's topic in Getting Started With Imaging
I would hold out for a cooled camera, as it will make your calibration frames much better and easier to apply. But it's a pity that you became ensnared by the ZWO octopus otherwise I would have suggested a S/H CCD camera which can be had for peanuts now. I reason why I would never even consider an ASIair. -
But of course we won't. The UK has form when it comes to missing the boat.

What does nothing look like?

The sensor looks quite "square" so I wonder if it could be an IMX 461 100 mpx job. That would need a *huge* image circle. In any case, we'll just have to wait 🙂.

This is the back of my old 183 camera From the photo it looks to be a bigger diameter.

As I recall SBIG had / have something similar, so not a new idea. Edit: After typing this I realised that it might sound like a put-down. It's not meant to be, I think it's a good idea.
