Hi
Did my deepest image of the Corona Australis area tonight with the mighty 300mm f2.8 flourite lens from Bert. Never before have I done such a long imaging run with such a fast lens, 90 mins, consisting of 5 minute subs
18x5 mins ISO400. 2 inch LPS filter in back of lens, modded 350D camera. Guided with Q guider on the cheap Orion 80mm shorttube guidescope. Done with object transiting, best possible position for imaging. It was quite easy sitting back in a chair manually guiding on the notebook pc with guidestar on a virtual recticle, greatly magnified.
The small scale image does not do it justice, so heres a 1
mb version. Even that is slightly downsized.
Of course from a dark sky site deeper images can be obtained, but from a site where the LMC is only just naked eye, its not too bad
