Getting Closer

Here it is, the first ever real shot through a telescope using the Canon EOS M. As mentioned before, the main reason for obtaining the EOS M was to dangled it behind a telescope!

If you have seen my web-page, I am mainly interested in wide field astrophotography, using long-exposure modified webcams and wide open fast scopes.
Tonight, I felt more of doing something quick and simple, the moon is showing a nice age, hence, the order of the day, a long lens with a short shutter time.

Canon EOS M @ Sky-Watcher MC90 (1250mm)

Of course, there if so much light that the settings could be really tuned towards low noise.
To establish focus, I actually used Magic Lantern's focus peak, despite my concerns about the health of the camera.

Parameters of this shot:
  • ISO 100
  • s/13
  • WB = daylight
  • RAW format
  • D=90mm
  • f=1250mm
  • f/13.9 (obviously)

 This shot was taken on a tripod but w/o any remote shutter release.

Post-processing in GIMP using a bit of noise reduction, a hint of sharpening and desaturation by luminosity. Finally, the image was scaled. No cropping though!

Just for your entertainment, this is what the colored pic looks alike:

More to come!
