Aha, my favourite subject. Glad multiple entries are allowed

don't worry, my opinion is already damaged! Gave up trying to convince long ago

Of course. I'm done now

I think you need to be inside, but that presents a whole other set of challenges, but if we could trap the FEs inside one it'd be more secure than Dave's polytetrahedron I reckon.

Now you're bending my mind ya eejit. I hadn't even thought of Mobius or Klein bottles. I'm sure we could make it work too if we had the capacity! I'm off to setup a Facebook page and get a following.

Unless it's hollow and open ended, maybe that cat lives inside - could be the answer to Schrodinger. But then there'd have to be a top and bottom so actually you're right.

Also, that Flat Earth Society page is hilarious. I've just been having a look. I saw that someone said this: Here's the biggest red flag. Do you know why no one has ever circumnavigate the poles.... Start at the North Pole and stay on the same meridian past the South Pole and back to north pole. East to west has been done. How come no one has tried to top that and circle navigate the poles.?????? Because it's physically impossible. There you go. It's not a globe I simply had to reply, I know I won't change their minds, many have tried on the inevitable discussion that followed, however I thought I'd have a laugh: Someone may have already pointed this out but I haven't got the stamina to read all this stubborn refusal to accept peer reviewed science so here we go. In your original post you acknowledge that east-west circumnavigation has been done. Think about that for a moment. That part of your statement seems to indicate that you accept that It's joined up around the east-west axis (see what I'm doing here, it's logic and reasoning). However you don't accept that it's joined up around the north-south axis. THEREFORE, the Earth must be a cylinder. Change the name of this page to The Cylindrical Earth Society immediately.

No, the wine is normal size, but the cat is huge - it's the size of South America. Must be one of those maine coons.

Looking good. The plaque looks very good too.

Oooh very nice Garry. First light report by tomorrow yes?

It's a bit good isn't it

You install the full version from https://ltvt.wikispaces.com/LTVT+Download (zip file) and it should just work. You can download higher res textures and dem files if you like but don't need to.

"Short" Washington Double Star Summary Catalog (Excel file - 26mb) From handprint.com (Bruce MacEvoy, Cambridge Double Star Atlas) He's got the full version with 117,469 systems but this one limits magnitudes to 10.5 for the primary and 13.5 for components, which gives a much more useful list. Enter your aperture and NELM and you'll get a list of doubles you should be able to split. Enter a minimum Q value for likelihood of a physical system rather than visual. The Q value and the observable/splittable values (based on Opik's subjective measure of difficulty - http://www.aai.ee/muuseum/Main/Downloads/T25_F_001_167.pdf) are subjective but useful up to a point.

Crack on sir. I wouldn't put your email address in a public space like this though mate, even with the at and dot bit. I've taken a note of it and I can always PM you on here, so edit and remove it

My first time too, looks like you have yourself a neighbour if the planners are listening (which they of course will be) Looking forward to meeting you

Booked

I've put together a few animations of sunset with correct libration as well, again using DEM data blended with one of my images for the texture which has come through especially well in the Copernicus animation. A script in LTVT takes care of producing the frames but the close ups 'wander' thanks to libration. A quick run through an imageJ plugin named 'align slices in stack' which corrects for this and you have a stablised view representing what you'd see at the eyepiece using a tracking mount (If you had the time, and the clear skies and fortitude to observe over a few days of course)

We have a terminator

Sunset over Montes Apenninus, with false colour topographical data from LOLA. None of my image in there at all. This is 40 hours at hourly increments, view is as seen from my observing location.

The southern highlands around first quarter are fascinating, so many shadow spires to see as the sun rises and the scene unfolds. I took one of my images of the region on the terminator for texture, deformed it to an aerial view and multiplied it with frames generated using DEM data from LOLA to produce this animation. I forgot to align the frames but it's ok, looks like it was taken by a hand held camera! The animation doesn't loop so refresh to view more than once. (you might have to click full size)

I've been playing some more. This is 2 images combined to make a full disk with a terminator as it was on the 1st of April this year. Underneath is an animation using the same image, projected as it would have appeared on each day of April. Thus, libration is achieved. Keep an eye on Vlacq down in the southern highlands near the terminator to really see the effect of libration. Now lets see if I can do one with the correct position of the terminator each day.

I thought I'd cracked this but the final blended projection from Photoshop seems to have lost resolution when imported back into LTVT. Still, it's pretty cool I think. Onwards etc This is made of 11 of my images. I also need to improve the blending.

Nice haul John. The John Moore is next on my list..... once my last order arrives!

Version 2. This is good. Tomorrow I work on producing cylindrical projections of as many 'terminators' as possible, compositing them with better quality in Photoshop and then see what happens from there. It'll be my very own near side relief map

This one is most interesting. There was a thread a while ago, one of @xtreemchaos mosaics I think it was where there was discussion about producing a composite showing the terminator across all of the moon, sort of a full moon detail mosaic. Well LTVT can do that too. Take your image, calibrate it and load it in LTVT. Then you can export it as a simple cylindrical texture file in bmp format. Do this for a few images where the terminator is at different positions, a little bit of Photoshop fun to blend them, save and reimport the texture. Bobs your uncle. This is just a section and it's low resolution but I think you can export sections to a texture file at higher resolution. I think this will throw up some interesting challenges around libration and illumination but it's worth a go just to see! This is 3 of my images with the most detailed parts cherry picked, showing a good portion of the moon
