  1. I'm pleased to hear this, Mel. I've used and appreciated the collimation guide myself. It's for sites like yours Mel that make the web wonderful.
  2. Need help explaining what I saw

    Ah ... OK. No cigar for me then!
  3. Need help explaining what I saw

    The lights on an aircraft advancing towards you or receding can appear to remain stationary. If it's turning at the same its flashes may be visible for a few flashes and then appear to stop.
  4. Why a concrete base 1m x 1m x 1m

    Something I'm curious about ...... Whenever I look at photos of an observatory base under construction it looks as though people have left in the timber form work surrounding the central block for the pier. If this true how can the pier base said to be truly isolated from the concrete pad?
  5. Yes, quite possibly. I'm only 50 miles or so south of you as the crow flys. It was between Altair and Vega at a guess, heading south. It was the most colourful one I saw.
  6. Sky cleared about 10 pm despite disappointing BBC and Clear Outside forecasts. Meteor watched from a deckchair looking south for about an hour or so. I've never done this so 'formally' before. It's a nice thing to do and gave me the chance to look closely at the various constellations in my field of view: Altair, Cygnus, Vega, Hercules, Bootes, the Milky Way and more. I recorded about 16 in the hour I was looking. Some were very bright and coloured. Some appeared to form a double streak. Is that possible? The moon rose in the east after 11 or so, a beautiful red colour, but it began to steal the sky's darkness. From my notebook:
  7. Hubble deep field

    The sky brightness was 21.6 mag/arc-second according to my sky quality meter. I have quite dark skies in Cornwall, at least at the zenith and towards the north, which the target was of course. I forgot to mention I used an ISO of 1600, whereas normally I'd be down at 400, but I was just going for maximum signal and not caring too much about image quality. I think it's fun to have a go at this sort of thing regardless of the skies you have.
  8. Hubble deep field

    The Sky at Night website still has the page describing the Hubble deep field challenge with star charts to show where the region is. Link here to Hubble Deep Field challenge.
  9. Hubble deep field

    HYep. I amongst several others on her have tried it. Here is my effort, but others did far better as you'll see if you search the thread. It was obtained on 19 April 2015. 14x150s + 10x300s canon 450D attached to SW 200p Newtonian, no Barlow. There's more than one Hubble Deep Field isn't there. This was the one near Ursa Major as I recall. Good luck! PS I forgot to add. The grey square is my effort next to Hubble's for comparison. And the lines and little rectangle show the expanded area of the frame it came from.
  10. 2 nights on the run after 2 years

    "Two nights on the run" I was expecting a jail breakout story. Good to hear you've got yer astronomy bug back.
  11. Hello to all from Cliffm

    Hello CliffM and welcome. Personally I find the "Unread Content" button (top right) the most useful way to keep up with the latest posts across the whole site. Dive into and explore the individual forums by all means, but frankly I find there are just to many to keep up with.
  12. Hello Boys (and Girls) .. I'm Back!!!!!!!!

    Welcome back. I hope you've got your towel with you.
  13. ASI1600mm cool

    Did you sort out the balance problem and if you did how did you do it?
  14. More clues to life on other planets?

    .... And what would be a truly profound discovery would be life on Earth not based on DNA, or at least sufficiently different that it was clearly not descended from the same progenitor as all life discovered on Earth so far has been shown to be. Such a discovery would suggest that there is more than one way for life to get going.
  15. More clues to life on other planets?

    You make a good point. It's appropriate to say these discoveries show that life is capable of existing in a whole variety of environments from the benign to the very very harsh. But as you say, such discoveries says nothing about whether life can initiate in such environments. We really don't know whether life needs a very specific set of conditions to get going or whether a whole spectrum of environments would be suitable.
