4 5 1. Intr oduction W elcome to the e xciting wor ld of astro-imaging. Y our new P arsec ™ Astronomical Imaging Camera is capab le of captur - ing prof essional quality astro-images of y our f a v orite celestial objects. Y ou can showcase spectacular images on y our com - puter , share them on the inter net, or pr int them. The camera’ s larg[...]

6 7 • LED Status Indicator: T wo LEDs on the P arsec indicate the camera power , exposure , image readout, and download (Figure 2) A Note about the Shutter The P arsec’ s leaf shutter moves freely when the camer a is off . Y ou may notice the shutter in an arbitrary position when removing the dust cap from the nosepiece (Figure 3.1). This is[...]

8 9 The camera’ s pixel siz e and sensitivity make the P arsec suitable f or most tele- scopes. For telescopes with v er y long focal lengths (2000mm and greater), y ou can optionally bin 2x2 (see section 2. Astronomical Imaging) to utilize greater sensitivity and obtain shar per images at the e xpense of resolution. Note that the P arsec 8300C ([...]

16 17 4.1. Focusing F ocusing the CCD camera is one of the most critical par ts of imaging. It can be challenging, but MaxIm DL has some helpful f eatures which will assist y ou when f ocusing your P arsec. Bef ore f ocusing, mak e sure your mount is polar aligned and trac king. F or best results, we recommend f ocusing on a star at least 30° abov[...]

24 25 Flat Fields A flat field is an image taken with unif orm featureless light entering the telescope, such as a b lue sky in the early mor ning or after sunset. Flat fields solve a n umber of issues in your astro- images. Vignetting Vignetting (Figure 21.1) in a telescope re veals edge-dark ening in the astro- image. The large CCD chip in the[...]

26 27 Each individual deep sky image is f aint and has a noticeable amount of noise . Combining the individual deep sky images eliminates the noise and enhances the detail in the deep sky object by impro ving the signal to noise ratio . The more imag- es you combine , the better the resulting image will look. (Figures 22.1 and 22.2). Read section 5[...]
