I must admit to a little chuckle at the bit in the description "and irreversible damage to the eyes " shirly they mean eye -singular? one would still have a spare with which to investigate what went wrong the first time ? Or is there going to be a bino viewer in a bundle? ok hat&coat Now has been changed to the singular, but no "ho ho ho" here, oh well

That is such really good news, it was so illuminating back then to read his blog, so sad when he departed. Well done, thank you.

And looks like you neatly caught the Lunar X and V being discussed over THERE Nice one !

actually, you were not far off, peeps have been known to fit copper foil/shim 'fingers'/tabs into the back of the sensor and extend out to a cooler, , , but that is a whole other topic ! very clever peeps.

Sorry, I was being a bit careless/fancyfull , old time phrase - to pay a skilled journeyman to do a proper job, an expression from days of yore when pans had copper bottoms.

Juan says "Camera modification: £55", so I'd be inclined to spend that £60 you just saved on the Baader to pay a man to copper bottom it. ?

He nearly 'did for' one of his eyes so you know what to wear ! Some call it luck, some call it skill ! The number of fails I read about I think you need to be prepared to face the £loss of bricking your camera if it all goes horribly wrong.

Thanks for the confirmation, yes, that was my dilemma I have been up and down his pages to make sure it was not my eyes (or dyslexica!) all very odd. Could there be two Baader mods / filters, cos someone posted earlier about it being a clear glass whereas I thought it (singular?) was for daylight colour balance, with a bit of residual/extra IR cut as well I wonder? If that latter were the case then for astro only use we would be better off without it ?? my head hurts !

Me muchly confussled as well ! Until this topic I thought I knew what I wanted, now I am not so sure, thanks y'all ! Ref the above pic, in that Juan is saying "ASTRO modified for astronomical use" on the top one, and on the lower he is saying "BAADER modified for astronomical use". In his other ads for other models he says "BAADER modified for astronomical use and daylight photography " which made me think that the Baader mod used a colour correction glass 'filter' to thus not need a custom white balance -but otherwise not needed for your astro only requirement-

True, but I am conflicted on this junk / novelty aspect. Every satellite needs, now, to have an end of life plan. Usually to de-orbit and burn up. So by rights the final burn should have been to lower perigee to cause the no longer needed dummy load to return to Earth, not to raise its apogee to 'out there' ???

which precise computer control of simultaneous firings makes one's thoughts turn to conspiracy theory - did they really mean to shoot for the asteroid belt after all, hehee ! Time for another coffee

Thanks. Yep, needed a bit more than the ZX81 they used for the moon landings and after all that they came back within seconds / inches of each other !

Very clever! and here https://spaceflightnow.com/2018/02/06/launch-timeline-for-falcon-heavys-maiden-flight/

Ah ! here : https://fsmedia.imgix.net/60/34/f9/bc/5d35/43a9/9c7d/1b4c88734a37/the-flight-path-for-a-perfectly-executed-falcon-heavy-launch.jpeg From https://www.inverse.com/article/41003-elon-musk-falcon-heavy-flight-path

Yes, most of my thinking (above) is in error because it starts with the initial velocity of the earth (so it is 'flying' relative), but not sure about the turning round and flying back bit, it all must be more-or-less ballistic ? Generally speaking it is more efficient fuel-wise to launch satellites into orbit with the rotation of the Earth than against it., so hmmm,, There is more to this than meets the eye ! all very thought provoking !

xxed in post, yes thanks, I must go do some reading / googling ! Save tearing out the remains of my hair

oh ! ding !! I think : but the Cape is not where it was, it has moved with the rotation of the Earth underneath it all, so , gosh that means that the timing of separation and the speed that they had achieved must be precisely matched to the rotation such that they fall back at exactly the right moment to "hit" the Cape at where it now is ? but such a narrow window would set an exactly defined weight to the payload, if more weight then more boost, but they would then overshot the Cape ?? meanwhile the centre core has gained extra speed so needs a boat to catch it ?? clever ! my head hurts, too much scratching !

Watching EM during the press conference he came over as a man of great good humour (or humor over there ) and the conference was a world away from the stilted stuffed shirts of yesteryear ! One thing though that is puzzling me, the thing takes off at huge great speed, flies rapidly (<understatement!) down range, boosters peel off, , ,then, how did they fly back to the Cape to land ? I saw no wings and extra motor. Scratches head ,,,,

He is going mining in the asteroid belt ! https://twitter.com/elonmusk/status/961083704230674438/photo/1?ref_src=twsrc^tfw&ref_url=https%3A%2F%2Fwww.theverge.com%2F2018%2F2%2F6%2F16983744%2Fspacex-tesla-falcon-heavy-roadster-orbit-asteroid-belt-elon-musk-mars but he miss-spells apohelion = aphelion

EM said during the press conference that they were "not going to re-use the core anyway", so I guess this has saved them the cost of taking it to the Council Recycling Amenity (and the car too haha !) They dont intend re-using the boosters either but he said that they did have some useful bits on them to recycle, so he was pleased that it was those that survived, not the other way round.

Thanks for posting the conference link very interesting.

Conference = "we were not going to re-use centre core anyway "

Updated ground track with revised inclination, still not enough to bring it over us https://twitter.com/Marco_Langbroek/status/961026756449890304

you are clairvoyant, I just got it !
