    had a good nite under the stars on Friday nite ( 16th Jan)

    did more comet pictures to stack, also imaged M42, Eta Carina and the Small Magellanic Cloud
    That last one I haven't worked on yet - will add to this thread when done

    M42 - The Orion Nebula
    15 x 30 sec images stacked, 2500 ISO, f5.6 @ 400mm Camera and telephoto lens were piggybacked on the telescope and its mount so I could do tracking ... avoid star trails

    M42.jpg


    This is the Eta Carina nebula
    5 x 30 sec images stacked, 400mm@ f5.6, 2500 ISO

    Eta Carina.jpg


    cheers

    That is a lot of time and attention in getting those two images. Thanks for posting them. PS: check Russ W's site for a bunch of photos - you can see a progression toward a really good quality image. Like these.

    Thanks Jim .... Yes, Russ does some really nice work

    Its a lot of fun with several disciplines involved ... Astronomy, photography and my weakest one .... post processing ;)
    and that bit is almost the hardest part, trying to produce an image that is as true to reality as possible

    Meh, screw reality. Make those pictures look as good as you can get them! After all, you can't see these objects like they appear in the pictures anyways, so there's really no 'reality' to go by. Well, that's my opinion at least. :-p

    LOL, Ohh I do my best to do that :) its just in various forums, I have seen images of some deep sky objects where the poster has seriously overcooked the image
    pushed the saturation etc to the extreme and it ( in my opinion) has been ruined

    OK here's the last of the 3 deep sky images from Friday night
    This is the SMC ( Small Magellanic Cloud) This is one of the 2 satellite galaxies to our Milky Way Galaxy

    6 x 30 sec images stacked, 400mm@ f5.6, 2500 ISO
    There wasn't much colour in this pic anyway, primarily just star fields so didn't try and push any colour into it ... .The bright globular cluster, lower centre, is 47 Tuc ( 47 Tucana)
    its only about 1/2 the size of M13 in the nthrn hemisphere and Omega Centauri in the southern hemisphere which are both really large globulars

    I hope to take more pictures soon, as I've been a long hiatus. My SBIG ST-2000XMcamera was just serviced by SBIG and I'm waiting on an e-mail from their service department so I can pay for it and get it shipped back to me.

    Will look forward to seeing some new pictures from you too :)
    I don't know how many other astrophotographers there are on PF, really only know of you and Russ

    By the way, I'm hugely jealous of your southern hemisphere location. There are so many awesome targets in the southern sky that I can't see.

    come on "down under" for a holiday :)
    we can head into the outback where there isn't a streetlight for at least 500km in any direction :)

    this Aussie song isn't the Aussie anthem but it almost should be .....

    Land down under
    by Men At Work



    Traveling in a fried-out combie
    On a hippie trail, head full of zombie
    I met a strange lady, she made me nervous
    She took me in and gave me breakfast
    And she said,

    "Do you come from a land down under?
    Where women glow and men plunder?
    Can't you hear, can't you hear the thunder?
    You better run, you better take cover. "

    Buying bread from a man in Brussels
    He was six-foot-four and full of muscles
    I said, "Do you speak-a my language?"
    He just smiled and gave me a vegemite sandwich
    And he said,

    "I come from a land down under
    Where beer does flow and men chunder
    Can't you hear, can't you hear the thunder?
    You better run, you better take cover. "

    Lyin' in a den in Bombay
    With a slack jaw, and not much to say
    I said to the man, "Are you trying to tempt me
    Because I come from the land of plenty? "
    And he said,

    "Do you come from a land down under?
    Where women glow and men plunder?
    Can't you hear, can't you hear the thunder?
    You better run, you better take cover. "
    Yeah!

    Living in a land down under
    Where women glow and men plunder
    Can't you hear, can't you hear the thunder?
    You better run, you better take cover!

    Living in a land down under
    Where women glow and men plunder
    Can't you hear, can't you hear the thunder?
    You better run, you better take cover!

    Jealous = me. Here, it's both cloudy and frigid. All the time. Until, like, April.

    yikes :(
    dunno when I will get the next chance .... been cloudy and sometimes raining since then
    It definitely was may last chance for the Comet Lovejoy pix

    Do you also do astronomy and maybe astrophotography, Andy ?
    Would be interesting to know how many of us there are :)

    How did I not see this thread and you guys talking about me? Thanks guys!

    davenn, I have a picture somewhat similar to that first one on my site.....except nowhere near as good. And that's an unbelievable number of (very sharp!) stars in the second one. Great stuff!

    I haven't done any atrophotography in like a year....I'm starting to itch again though...

    Agreed. As long as you aren't literally painting it, pretty much anything is fair game to me.

    I bought a Colin Hay solo album after he did a bit on "Scrubs" playing "Overkill" while following a doctor around all day (in a halucination). And the best I can do for dark skies is driving 100km from Philadelphia to some 600m "mountains" and freezing (because it is only clear in winter) in a random parking lot somewhere (with no beer, so I can drive home at dawn). Your way is better.

    Hey Russ

    that's cuz we were talking about you not to you hahahaha joking :)

    seriously, please get back into some astrophotography, as I am encouraging Drakkith to also do so. It would be great to get
    regular content put up in a thread showing images, and seeing the improvement in them with our collective growing experience etc
    I know I would enjoy discussions on imaging and post processing etc

    cheers

    Where I went for these pix is an hour's drive out of the city its good for looking west, but still a lot of sky glow to the east from the lights of Sydney
    For really dark skies, I need to travel some hours to the other side of the mountains and stay in motel overnight.
    Now knowing what the camera and lens is capable of, I may make that effort periodically as we head towards winter

    Dunno about you, But I find with older age, I just cannot handle the cold nights like I used to haha
    It takes a special astro event and some effort to drag the scope outside in recent years ;)

    Yes- when the weather turns nicer, I try to get outside and enjoy the night sky. Hopefully I'll be able to post some good ones this spring- I missed my chance to image the Virgo galaxy cluster last year.

    Fair enough- here's some from last summer/fall: One with my telephoto lens (400mm) of Andromeda, 1 hour and 40 minutes of integration time:

    1h_41m_zpsjq4wn408.jpg

    But I also discovered some real benefits to wider fields of view: here's 2 using my 85mm, one is a full frame photo of the Milky Way and the other a 1:1 crop of a region in Cygnus:

    16_fov4_filtered_zps7bcpbsta.jpg

    cygnus_zpsnuupm8a9.jpg

    And finally 2 with my wide angle lens (15mm): a 5 hour 'star trails' photo and a stitched-together Milky Way image
