Re: NASA Apollo Saturn V to launch as LEGO brick model June

I gather that the Saturn V model has 1,969 pieces. Not sure if this is intentional or not!

Optics Advice Please

Hi All,

Could someone provide (or suggest a link to) a really straightforward layman's explanation about optics, including the relationship between focal length and field of view?

Thanks in Advance,

Re: What now for US space science?

I wouldn't be surprised if this leads to the Trump orbital casino, the Trump Moon hotel and 'Space Race 2'!

Re: University Astronomically Challenged

I suppose getting Ursa Major and Canis Major mixed up is easily enough done for a non-astronomical person! :lol:

Re: Peter Grego

The news about Peter came as a shock.

We first corresponded in 2006 when he contacted me about a Transient Lunar Phenomenon observation I'd made. Peter was a brilliant lunar observer and draughtsman and his passing is a terrible loss.

There's an Exploring and Understanding The Universe Facebook page if you'd also like to drop in there for an astronomy chat and post your comments or questions. :)

Secondhand Celestron C8-NGT

Hi All, I've got a Celestron C8-NGT Newtonian I'm interested in selling. I had a serious illness over a year ago and have been recovering since. The 'scope hasn't been used for about 18 months and could do with a good home rather than gathering dust. I think maybe it's time to take up solar observin...

Preferred Settings For Constellation Photography?

Are there any preferred settings for constellation photography?

I'd like to get some images of constellations (Orion, etc) and am thinking that f2.8 at ISO 800 (or faster?) for an exposure of 5 - 10 seconds should do it?

Macaque Monkey Mars Mission?

Hi All, There are various articles circulating that Russia is training macaques to fly a mission to Mars. Can anyone see a point to this :shock: ? Humans have spent months at a time in Earth orbit and in ground-based simulations for decades now, so we know the requirements for a Mars mission anyway....

Re: Lest we forget our pale blue home

Thanks for posting Brian.

I'm reminded of Carl Sagan's 'Pale Blue Dot', especially at this time of year.

V774104 Query

Dear All, I'm presently studying an online course about Moons of the Solar System. A fellow student has asked why the recently discovered Trans-Neptunian Object V774104 is designated as such (OK, I realise it's not a moon !). It set me wondering too, because I thought that TNOs were given a sequenti...

Re: A Scilly surprise

I'm intrigued as to the path this chunk of rocket might have taken over the past year or so. Would it have merely been floating about on the surface, swept into the murky depths before eventually being washed ashore, or even drifted backwards and forwards across the Atlantic? We shall never know.......
