M65 - Spiral Galaxy in Leo


M65 is a spiral galaxy that is a member of the famed Leo Triplet group, which also contains M66 and NGC3628. M65 is a typical-looking spiral, suggesting that it has not been strongly affected by the gravitational fields of its neighbors. It is generally low in gas and dust. Therefore its rate of star-formation is relatively low.

M65 was discovered by Charles Messier in 1780. It is estimated to lie 35 million light years away and have a diameter of 95 thousand light years.

Telescope: Celestron C11 Edge HD @ f/7
Camera: Modified Canon 650D; raw capture; ISO 1600
Mount: iOptron CEM60

Images were focused using a Bahtinov mask and the camera's live view function. The subframes were calibrated, aligned, and combined in ImagesPlus. The composite image was adjusted in Photoshop. Sharpening and noise reduction were done using Topaz Detail and DeNoise respecitively. Vignetting was adjusted using Gradient XTerminator.
