Date/Time of photo
February 2006
Equipment
Meade DSI pro II and an 10"LX200 @ f3.3 & 6.3
Description
This is a combination of a series of images captured with the DSI pro II. The overall image was taken @f3.3 using drizzle technology. Two versions of the same image were used, one to bring out faint detal in the outer arms and other to compensate for overexposure of the nucleus. Other images taken @ f6.3 were then scaled down in Photoshop and combined with the f3.3 data to give sharpness and greater detail to the nucleus and brighter out arm patches.
