Description

Using the big Dobson for a close-up view. The new derotator allowed precise framing of this colorful region of Orion without the need to crop out field rotation. This image was originally captured as a 5 minute live stack.  The FITS file of the stack was later used for further image enhancement with Startools to produce the image shown here.
