M45 wide field and 100% crop

The result of stacking after processing, but before cropping. Processed to enhance the stars.

There is still some vignetting despite the use of flats, and some banding from the sensor is visible as I stretched the image to pull out the nebulosity.

The stars were trailed due to poor alignment. "Fixing" them in Photoshop has helped, but they are still not round.

M45: The Pleiades

The Pleiades or Seven Sisters, number 45 in Charles Messier's catalogue of nebulae is a well known asterism and nebula in the constellation of Taurus (the Bull) and is visible in the autumn and winter skies. I took this image at the end of last year in Langkawi in Malaysia.

Olympus ZD-150/2 lens @ f/2.0 on E-620. Kenko SkyMemo-R mount. Pre-processing in IRIS, post-processing in Photoshop CS5.

I'm still learning how to process images. It's hard.
