    Default Galaxy NGC2997

    Bought a new astronomy camera a few months ago but it's been so cloudy I haven't had much of a chance to use it. But did get some sky time the last couple of nights.

    NGC 2997 is a face-on unbarred spiral galaxy about 25 million light-years away in the constellation Antlia.

    Taken over two nights, Luminance the first and RGB with an Svbony LRGB filter set the second. GSO 10" F4 Newtonian, ZWO ASI 183mm Pro cooled to -10C, 719 x 30 seconds unguided on a HEQ5 Pro.

    Nice bit of kit you have there LJ I would love to be able to purchase a decent 'scope. We bought a 4" reflector for our son about 30 years ago and would love to get one for ourselves now. Problem is, time and money!
    I'm out of my mind, but feel free to leave a message...

    That's never a good combination. I have time, but money is more scarce than ever now. There's some good stuff coming out of China these days. I can't even build it as cheap.

    Anything you could recommend or traps to watch out for?
    China in general has been for me always a hit and miss.
    This era of thoughtless consumption must end so we can encourage a world of creative geniuses rather than consumer idiots.

    Well the really cheap stuff is still crap. But good quality gear can be found. You still have to do some research on the item in particular. Usually someone has already bought it and will appraise it one way or another. My camera for instance had a 20 something page thread on it on one of the astronomy forums so knew what I was in for.

    I just cracked myself up.
    Can you do better than that Learjet?

    The reason I ask is because my local astronomy club is going to have a competition soon with some serious prizes.
    I think you'd be in with a good chance.
    Yes I am an agent of Satan, but my duties are largely ceremonial.

    I'm still learning ow to use the camera! It has a very steep learning curve and I'm at the bottom of the ladder lol.

    When they open the comp I'll let you know. The purpose of the competition is to encourage people like you.

    This might give you some inspiration. This is a real time image from one of our telescopes of Eta Carinae. Exposure time on the CCD is less than 1 second.
    I just took a photo of the laptop screen with my phone. It's a bit tragic how easy it is to use this bit of gear.

    Eta Carina is very bright. Over the years I've done it to death, but I guess I should have a go with the new camera. Problem is it's been cloudy for months. The above photo was a rare break in the clouds.

    This is Eta Carina in 60 seconds with a Canon 1100D DSLR + 10" F4.

    Thanks for that LJ, you have encouraged me with that photo and bit of detail. I wondered how you'd get on with a standard DSLR. The 1100D is only one step above mine. (1000D). Even that telescope looks like something I might be able to afford given a little time.
    I'm out of my mind, but feel free to leave a message...

    I forgot to mention the $2000 mount. But yes, old DSLR cameras are fine.

    Yeah! That could be an issue!
