    Well tonight was the big test, it was the first time that all (well nearly all not that new camera I got) the recent tweaks I had made to my Deep Sky Imaging setup had come together

    My 350d with the filter removed
    My Guiding setup
    A new bit of guiding software

    and critically the Macbook pro - my Acer had poor usb power as it turns out ( not something that would matter for a mouse but for sub pixel guiding of optical equipment its quite important

    First Target in Cygnus the Swan was the Pelican nebula

    These are summer objects and low down in the sky but I was just desparate to take pics of some nebulas again

    Hope you can tell why it is called the Pelican

    (these look better if you click the enlarge bar then expand the image)

    2 hours worth of 7 minute exposures at iso 800 all stacked and then calibrated, tweaked in photoshop
    [​IMG]

    I need to spend some time fiddling with it to make myself happy but it will do for now .

    And an hour of the same length Subs on the North American Nebula

    I especially love the 'Mexico' region.

    Last year I really really struggled to get these images by lightening the image to the point of whiteout, now with the new setup I was 'darkening down!'

    Definitely getting there :D

    oh wow, they are absolutely incredible. The boys and I have just been sitting here looking at them saying "wow" "that's amazing" "they're brilliant" and other such phrases! They'd make awesome posters Chris :yes:

    You are very kind, I suspect Keiths reaction if he ever reads this will however be mainly 'phew' :D

    An element of phew :lol: but more just WOW! You see these images in books and think they've been taken from multi million pound observatories with huge scopes. Somehow when a friend takes them from his garden it all feels a lot more real.

    I can actually see the pelican! Herself will be as amazed and awed (she's a particular fan of pelicans. :yes: ).

    I have this image of you in the garden in the dark of the night, staring up at the sky, and peering through scopes...it's comforting and awe inspiring all at the same time.

    Please don't ever stop sharing the universe with us. :hug2:

    Re: 2 Nebulas from last night with all my new kit working

    Mum - of course I don't mind I would be flattered :D

    Keith - not quite millions of pounds but if you add it all up it is a bit :mental: like any hobby :lol:

    These two actually sit right next to each other the pelican on the right some of the stars are on both pics but trying to do a mosaic would be :mental:

    Nut the individual subframes look pretty much like the finished product and I shoot in L (curve) not in RAW each photo is just a little noisier than the combined effect of them all - then this 'sandwich' of 20 photos has bias frames subtracted as well as dark frames of equal length with the lens cap on this removes all the hot pixels and noise from the sensor getting hot with such long exposures. In order to 'see' these you would need a dark site and quite a big scope.

    :yes: you can Lozzy :lol: as you are so close we really ought to get around to that meet up to have a look sometime :D

    Hmmm just looked at these on my iPhone and they look dark and horrible. That is the problem with digital photography so much of it depends on monitor settings :(

    Spectacular Chris! :thumbsup:

    Now take some of these magnificent shots of yours, import them into iMovie, add some transitions, some titles, a lovely sound track (preferably not Also sprach Zarathustra), post them on YouTube and show us whatcha got!
