    Default M 13 from Sunday



    Hi all

    Sunday was clear but the seeing conditions were awful as described in my earlier post of "M 3 on a murky night". I took this shot later in the night again when M 13 was high enough to get anything decent recorded. This is one of the subjects that I have been wanting to try again as it was my first ever attempt at imaging when I still had my Meade LX200 system.

    This was taken with the Takhashi BRC-250, Starlight Xpress SXVF H36 on a Paramount ME, exposures are 30x1 minute each for RGB unguided with just simple auto dark subtraction in Maxim DL, no other calibration was used. As described in my M 3 image the top and bottom of the image are croppeddue to some dark lines about a 1/6 from the top and bottom of the subframes (not sure as yet what is causing this as it hasn't happened before).

    The glare round some of the brighter stars is caused by the poor seeing so it isn't as sharp as I was hoping. You can compare this with my first attempt at this subject by looking at the first image in the star cluster section of the image gallery of my website Imaging The Heavens - Home Page

    Thanks for looking

    Best wishes

    Gordon

    Just incredible Gordon! What a great image, and it's got me really looking forward to hunting this cluster down next time I get to view to the East.

    BTW, what is that galaxy sitting up there at the high 2 o'clock position?

    Thanks for the photo. I was also wondering what the galaxy was in that photo, may have to consult some charts.

    The galaxy NGC6207 is a nice contrast to M13 but it is difficult to spot in light polluted skies.
