Jupiter

tmf3lehigh · 16th of August 2009 (Sun)

This is my first post in Astronomy and Celestial. I saw a post the other day on Jupiter and its moons and decided to give it a try for myself. I used a 500/4 with a 2x extender on my 40D (Wimberley mount, no tracking). The single image was tweaked in Aperture and noise reduced with Nik Define, and then cropped. Ohh, and this was shot in northern NJ, 12 miles from mid-town Manhattan, so not the best dark sky conditions.

I'd appreciate any comments and suggestions for improvement.

Excellent shot. That 500L is something isn't it? One day...

This is the original, unprocessed image:

You did this without a telescope?! Wow

Excellent shot!

Adrena1in · 17th of August 2009 (Mon)

That really is impressive. Far, far, FAR better than anything I've ever managed with my 1200mm telescope!!

Yes, a single image. I took multiple images--would stacking them help? I also took some bracketed exposures.

No telescope, although I would like one. I just don't know if I'll have much use for one where I am located.

I guess when factoring in the crop factor of the 40D, this was taken at 1600mm, and then cropped significantly.

Bernoulli · 17th of August 2009 (Mon)

Not 1600 mm, you're at 1000 mm. The crop factor doesn't enter into the focal length because you're not full-frame. Think about it, those pixels in the middle of your sensor have no idea how big the sensor is, so this would have no effect on the magnification.

Having said that, at 1000 mm I think you CAN consider that to be a telescope!
