    Finally got a bit of clear sky tonight. It is plagued of course, by that whopping great beacon in the sky, the moon, but never mind I thought I would make the most of it anyway.

    Tonight I thought I would remove the telescope from the mount and just pop the Canon 400D on by itself so I could track the stars for a few minutes inside the dome.

    First one Milky Way Galaxy widefield 18mm F3.5 ISO 800 3 minutes

    Second one Antares Rho Ophiuchus region 55mm F5.6 ISO 800 6 x 3 minutes stacked - total 18 minutes

    This is the first time I have attempted to photograph a dark nebula. (Rho O)

    The big fella upstairs has made some pretty awesome things up there I reckon. I'd love to go there one day and see it all for myself!

    Hope you like em!

    Baz.

    The Gallery is over there ---> ;)

    And yes, they are very lovely. Big Guy is definitely awesome.

    Just out of curiousity, these seem soft, is this a result of having to adapt the camera to the scopes? Or more to do with the observatory being earth bound?
    I guess astrophotographers try to keep post processing to minimal so as not to introduce 'random' elements that could be mistaken for a new star/planet... ;)

    Yes, they are a bit soft. Stars are very unforgiving when it comes to focus. As you can see, this is not through a scope. It is a standard, off-the-shelf Canon with a standard kit lens 18-55mm.

    I was just experimenting by putting it on the telescope mount for tracking.

    Let me get this straight. Using the standard kit 18-55 IS lens, you had it on a tripod and pointed it at the sky for 3 mins at ISO 800 F stop wide open, and got that?

    I've had a *small* play with pointing at the sky, but just didn't know how long to leave it open for.

    Yes that's right, except instead of a tripod, I had it on the telescope's polar aligned mount, so it was tracking the stars motion.

    Very cool shots man. Like I said on POTN I am still waiting for my scope. Patience is a virtue in this game, huh? Haha.

    Ha HA! You know it!

    If you are not patient then either astronomy will teach you patience or astronomy is not for you!

    Patience is when you hand track for one hour.

    I've wanted an equatorial mount with a tracking motor for ages. It makes these so much easier :).

    Anyway, nice job :). Focus is a pain with the kit lens and the nifty 50. Once I focused on a bright star (well, it was probably Jupiter of Venus) then put some tape over the focus ring.

    Sometimes you get lucky too and the camera just nails it :).

    Anyway, nice shots man, keep posting more!

    or focus and then flick the switch from Auto focus to manual so the camera doesnt change it.

    50D user here, i usually use the live mode and zoom in digitally, go to manual focus and set the focus and works OK

    Nice shots mate!

    That works great for good lenses. But the cheaper lenses have wobbly focus mechanisms which rely on the auto-focus to continually adjust for the wobble. Hence why the tape is required. It's also very easy to accidentally move the focus on the 50mm f/1.8 as there is very little dampening in the focus ring.
