    Default NGC3293-NGC3324 Carina



    Target: NGC3293 and NGC3324
    Camera: Canon 350d Unmodified
    Exposure Capture: Aperture Remote
    Scope: Stellarvue 80ED f/7
    Mount: EQ6 Pro
    Exposure Setting: Prime focus, ISO800 ICNR off Daylight WB
    Exposures: 9 x 5 minutes taken 8/1/09
    Seeing: Bad, LP, half moon etc
    Guiding: Orion Starshoot Autoguider using PHD
    Focus: First unsuccessful attempt at using DSLR Focus
    Stacking: DSS
    Processing: PS7, PS CS3, PSP

    Info: Situated in the Carina

    NGC 3293 consists of more than 50 stars in a 10 arc minutes field, the brightest of which is a red giant of mag 6.5, between many hot, blue bright stars (the hottest of spectral type B0). Rests of some nebulous materials are visible in our image, floating between the stars which have probably formed from them. With an estimated age of only 10 million years, NGC 3293 is a very young cluster.

    NGC 3324 is also called the Gabriela Mistral nebula, because of the striking resemblance with the Nobel Prize winning Chilean poet, who was born and raised in the Elqui region, home to the Cerro Tololo, Cerro Pachon and Cerro Morado professional observatories

    Awesome! great work there Trevor. Has DSLR focus increased your sharpness at all? You mentioned it failed, in what ways did you unsuccessfully use it?

    Can you give me some ideas on how you align - do you use drift alignment and/or polar alignment with 3-star align? Do you also have goto?

    Again some very nice work, Trevor.

    I am going to link this over to a couple of our beginners who are experienced photographers but new to astro. Great demonstration of the results that can be and are often achieved with a DSLR and a good quality small refractor on the right mount.

    Good stuff

    Unfortuantely in this image I did not acheiev critcal focus. With DSLR Focus the idea is too make sure you follow the instructions and acheive as small as star possible in your capture frames with a peak value of 200-230.

    Take your time here as it's critical for the final image. Once you think you have acheived the best focus possible then lock down your focuser and check focus again before commencing your imaging run.

    Unfortunately I can't even make out Octans in LP skies and I've yet to try drift alignment in earnest. I use 2 or 3 star alignment on the EQ6 and then rely on my autoguider to do the rest.

    Alas during the week I don't have the time or patience to worry drift alignment or perfect polar alignment because my window of opportunity for imaging is only between 9pm and 11:00pm. Although I have marked the ground where I set the mount up so I'm roughly pointing in the right direction.

    Attached is a smaller reprocessed image.
