    Hi folks

    13 hours cumulative exposure (6 Ha, 7 OIII) taken with a CDK17, STXL11002 all AOX guided. The OIII data was pretty spectacular (FWHM 1.2 - 1.5) which allowed me to tease out such fine detail in the 'Helmet'.

    thanks for checking it out.
    cheers
    Martin

    Superb! Am jealous! Take a look at Robert Schaeffer's effort - a much more humble setup, and he's learning.

    to: Martin Pugh , 'I don't know if I seen an image of Thor's Helmut that looked that good before … what are the length of the exposures
    and the approximate Gain of the CCD ? … I have DSLR's so it would be ISO '.

    Thanks Robert
    I use a different style of imaging to you such that ISO values are not used in astronomical cameras. Whilst SBIG camers have a gain, it is set, and not adjustable like it is in a QHY camera for example. My NB subs are 30 mins or 1 hour, depending on the target, all guided with an Adaptive Optics unit.

    Keep up the good work.

    Cheers
    Martin
