$RB-60 Refracting Telescope - Meade$

Field De-Rotation Description of Drizzle 7 Instead of just tracking and stacking images by following the movements of one star, the Envisage Software with Drizzle will track and stack images locked on two stars, and can correct for image rotation that occurs if the telescope is tracking in the Altazimuth configuration, or in a roughly polar aligned telescope. Using this feature, you can do a quick alignment of your Meade telescope in Altaz, turn on the Envisage, select Drizzle, and draw a box around each of two stars in the field. The resulting image will not show rotational star trails. 52
Multiple Cameras: The latest software release now supports guiding and imaging with multiple cameras: You can connect up to 5 and use any combination of DSI, DSI Pro, DSI II, DSI Pro II or LPI. But you must use a USB 2.0 interface and, if necessary, a powered hub. Make sure you have enough power in your ports to run all your cameras. Drizzle: The Drizzle function has been sped up for all models. Color Algorithm has been improved on color imagers. Zoom: If you check the zoom percentage box, you can zoom into the center of the image. If you draw a selection a box around a part of the image, you will zoom into that part of the image. Select a zoom percentage from 100% to 500%. The zoom check box and zoom percentage box are displayed on the tab directly above each live image screen. Change Stretch on Completed Images. When an image is completed you can now alter the histogram stretch values and save them in the final image. Just pull down the file->save menu and the image will be saved in the current file time. You can also change the file type in Save Proc... and then save again in the new type. Image Files imager type. You can now rerun images through Drizzle or shift and combine by using the Image Files tab. Use the Add button and browse to the files you want to use and select them in the order you want. Then click on the first file in the list and it will appear in the corresponding Image File tab like a live image from a camera. Draw a box around one or two stars if you want de-rotation and press the start button. The image will start building and automatically stop when all the file images have been processed. It is recommended that the file type FITS3P be used for the image files because you can process with the full 16 bits from the DSI. More... New Features in this Release 53
