M106 / NGC 4258 - Spiral Galaxy in Canes Venatici

	M106 / NGC 4258 A spiral "neighbor" about 23 million light years away. Location: Canes Venatici Magnitude: 9.1 Date: April 17/09 Camera: Meade DSI-IIC Exposures: 21 Exposure length: 30 seconds, guided Gain: 63 Offset: 0 Notes: Guided in RA using Meade DSI-pro camera on ETX-90 piggyback setup. Clouds rolled in early, leaving me with only 21 frames to work with. A longer time exposure could be expected to produce much improved detail. Another smaller galaxy can be seen in the lower right corner.
