    Description

    Last image from astrocamp 2013.
    This is mostly the result of some integration time made in this August astrocamp. Some more exposure time is been added from 2012 astrocamp using the same equipment. Finally a little bit of integration I've acquired with another telescope at an higher resolution an focal lenght is also been included. The result is an RGB image of about 120:120:120. I've made a syntetic luminance using the sum of the RGB colors and I've also added 30 more extra minutes of Ha data taken from the city this year.
    The gears used are: Takahashi Epsilon 210 f3 telescope on a Astrophysics Match1 GTO mount with a QSI 683 WSG8 ccd camera using Astrodon gen.2 filters (5nm Ha). Guided woth a Starlight Xpress Lodestar camera.
    The other setup was an Officina Stellare UCRC320 f5.4 on a Paramount MX with a FLI microline 11K sensor using Astrodon gen. 2 filters guided with a Starlight Xpress Lodestar camera (he contribution was only 30:30:30: RGB.

    Thanks for watching!
