Drizzle Tutorial #1
This tutorial demonstrates the basic operation of Drizzle and how you get started. The following tutorial assumes
that you have the imager on the telescope pointed at a Deep Sky object properly focused and that dark frames
have been taken up to the longest desired exposure time.
Recommended settings
File Type -> FITS3P
Save Options -> Save All Uncombined Images
The above settings are highly recommended. FITS3P will save the full dynamic range of the imager and “Save
All...” will allow you to run the images back through drizzle offline allowing you to try different settings. These
setting are found by pressing the Save Proc... button on the imager tab.
1.
Select “Drizzle” from the “Image Process” dropdown menu.
2.
Enter a name in the Object Name box.
3.
Set Min Quality and Evaluation Count as desired.
Press the Settings button. See the Drizzle Resolutions section of this document for a description of these
settings. These settings are not critical if you used the recommended settings above because you will
be able run the images back through drizzle off line.
4.
Start autotracking
Follow the directions in the manual on page 31 and set up your Meade Telescope for autotracking/Guiding.
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.
