Page 15 Click OK when it is covered. The program will display how long the Dark Frame exposures will take.
Page 16 Stop to abort. You will now have an image that you can post on the web or submit to one of the Deep Sky Imager user groups. Experiment with Contrast, Shadow Enhance, Histogram sliders and Dark Subtract, and you will begin to take images like an expert.
Page 17 The Parfocal Ring It is extremely useful to have the Deep Sky Imager camera and a telescope eyepiece be parfocal—it will save you time when you need to refocus. Parfocal means setting two or more eyepieces to the same focus. In this case, one eyepiece is a camera.
In other words, if you focus one eyepiece in your telescope, then you remove it and replace it with a parfocal eyepiece, the parfocal eyepiece will require little, if any, refocusing. Page 18 Do not tighten the eyepiece holder thumbscrew. Make sure the Deep Sky Imager camera slides down as far as it will go into the eyepiece holder.
Point the telescope at a terrestrial object that has a lot of contrast with the surrounding area and if possible, has a distinctive edge like a building, for example.
These controls are automatically set after you pick an Object 10 type and click on the Auto Exp button 3. Most users will seldom, if ever, need to set these controls manually.
Experiment with these sliders to change to change the image color. These are field that may be filled in by the user, if so desired. It also contains the directory paths for the Images and Dark frames directories. Each time the Envisage program begins to accumulate a new composite image, it renumbers the image in a new tab, using your original name.
Also a box displays the images format e. Image Directory field and Browse button: Click on the Settings menu 25 to display a dialog box. Click on this button and your directory list displays. Choose the desired file and it opens as a tab above the Image Display window.
See diagram below. Page 25 Magic Eye Focus The Magic Eye Focus 22 displays a 3-D surface plot of the intensity of the image centered on the crosshairs of the tracking box see page As you adjust the focus, the peak of the plot will grow or shrink and the edges will grow steeper or less steep.
Best focus is achieved at maximum peak and steepness. Page 26 Connecting your Telescope and Telescope Controls To connect to your telescope, see the printed instruction sheet that was including with Autostar Suite.
Once the telescope is connected, you may use the following controls 28 : Use the Arrow keys to move the telescope. Click on an Arrow to move in that direction at Guide Speed. Page 27 Time-Lapse Settings Envisage software allows you to take time-lapse images of an object. This means you can set the software to take an image, wait and then take another image after a period of time goes by, and continue the process for however long you desire.
Page 29 Tracking Boxes and Centroids Drawing a tracking box allows you to track that is, to follow a bright spot that is surrounded by a dark area. A centroid is the spot where the crosshairs meet. You can use the centroids to help you center an object in a box. Page 30 Histogram Display and Controls The Histogram controls allow you more control of the brightness, contrast and mid- range tones of your Deep Sky Imager camera.
Experiment with these controls. Select an easily focused terrestrial image and adjust the Histogram sliders. You will notice the Live image growing brighter or darker, and even notice mid-tones becoming more visible. An autoguider helps keep an object centered so that a 35mm camera can take long exposures of an image. Page 32 Autoguider and Telescope Controls 7. Focus and prepare the imager as described earlier in this manual. The telescope models will follow some telescopes will move more slowly than others.
Set Target: Click Set Target and click on a position on the screen. The target will move to the this position. Corr Correction Gain: Sets how aggressive the correction operates. Page 34 A similar process is needed for the Deep Sky Imager which can be thought of as a canvas for a fine painting, only in this case the canvas is the silicon surface of the imager.
This silicon surface is uneven in a different way. Longer exposures and temperature can create noise in your Deep Sky Imager camera called dark current artifacts. The Dark Frames feature allows you to subtract out some of this noise from your pictures. Page 36 7. Check the Dark Sub check box 6. The Dark Frames feature is automated, so Dark Frames will automatically be applied to any pictures you now take. Remove the lens cap from your telescope or uncover your Deep Sky Imager camera.
Click on the Save Process button to open the dialog box. Set the file type. Thread the nosepiece into place and firmly tighten. Push the slide into housing Attach nosepiece. Gently push the slide into slide housing on the camera.
Page 40 4. Be sure the Imager pull down in the Telescope tab is set to the imager you are using for drizzle. The imagers are identified by name.
Page 41 Drizzle Tutorials 5. Select 2 stars The first star selected will be the shift star this is the position that will be shifted for subsequent images. This is also the star that will be used for telescope tracking. The second star is to determine the rotation angle from the first star. Page 42 Drizzle Tutorials Once the star reaches the first target position the yellow cross will move to the lower right corner. The target position will move to the next position each time the selected star reaches it.
The next position is the lower left corner and the last position is the upper left corner. Page 43 Drizzle Tutorials 2. Select images Select the first image in the list and after a few seconds it should appear in the live display. You can use the arrow keys and go up an down the list and the image will appear.
Inspect each image and click on the Remove button to take the bad images out of the list. Page 44 Drizzle Tutorials Click on the first file and then select the tracking stars. Jump to content.

It seems Envisage has changed drastically from the original disk I got with my LX to the latest update so where or how do I get a updated manual?? Seems Meade is asleep at the wheel when it comes to instructions on how to use their equipment.
I have looked all over the internet granted maybe in the wrong places but seems this should be an easy find on Meade's site right next to the update software. I have the old manual in PDF but it does not evcen look like the same program that is the 7.
