3.4.Analysis (Figure 10)

The Analysis window displays quantitative data from the image pertaining to pixel brightness and star diameter. Your mouse cursor position will focus on that region of the image for the Analysis display (Figure 10). The information displayed is very useful, but for beginning astro-imagers, concentrate mainly on getting the smallest HFD possible when focusing on a star.

as 65535 ADUs in value. The image

 

will start to saturate (or overexpose) at around 50,000 ADU. This demonstrates the large range in brightness that 16 bits of data has, and is one of the reasons the StarShoot G3 can capture dynamic images with faint detail.

Maximum

Displays the highest ADU pixel value for the immediate area.

Minimum

Displays the lowest ADU pixel value for the immediate area.

Average

Displays the average ADU pixel value for the immediate area. This is useful to see the general value of an area without letting a hot pixel throw off your reading.

Std Dev

Displays the standard deviation for the immediate area.

Global

Displays the Std Dev., Average, Maximum, Minimum pixel values for the entire image.

Star

Pay attention to the Half-Flux Diameter (HFD) value when pointing the mouse cursor at a star (Figure 10), to determine the best focus. The smaller the HFD, the better the focus.

The following sections will describe more software features which you will encounter during your imaging session, and later on when you are ready to process your images.

Now that you have familiarized yourself with the basic functions of the camera and software, you are ready to begin using the StarShoot G3 to capture images!

4.1. Focusing

Focusing the CCD camera is one of the most critical parts of imaging. It can be challenging, but Camera Studio has some helpful features which will

assist you when focusing your G3. Before focusing, make sure your mount is polar aligned and tracking. For best results, we recommend focusing on a star at least 30° above the horizon (or higher). Follow these steps to achieve an accurate focus:

1.Find and center a moderately bright star through your finder scope. Try to find a star around magnitude 4 or 5. If you are not using an optical finder or just using your unaided eye, the star should look relatively faint. This is important because brighter stars will easily over saturate the camera and compromise the focus accuracy.

2.Center your telescope on the star using an eyepiece. Make sure the right ascension (R.A.) tracking motor is engaged on your mount.

3.Replace the eyepiece with the G3.

4.Connect the G3 to your computer and open Camera Studio. In the Camera Control tab, click Connect.

5.Go to the Capture tab, set the Exposure to 1 second and click Single. You should see the out of focus star in the image. If you do not see anything, you need to increase the exposure time.

6.Draw a small box around the unfocused star with your mouse (hold-click and drag the mouse cursor around the star to draw the box, Figure 11). Check the Subframe box.

7.In the Capture tab, click Loop. The camera will only download the area you previously selected, which makes each image download significantly faster
