In this video I show my Lacerta MGEN-II autoguider setup for Skywatcher Star Adventurer. With this settings I reach 100% sub utilization at 400mm focal length and up to 240s exposure time.
See all my guided 400mm images on Astrobin.
With Star Adventurer guiding is possible only in RA axis. An accurate polar alignment is still necessary. Auto Guiding only can eliminate the Periodic Error of the Star Adventurer worm gear.
And I’ve to say, the MGEN does it very well 😉
With the following settings I reach a very well guide quality and quick star search.
Of course the DEC guiding is disabled for Star Adventurer.
The Random Displacer moves the field of view a few pixels on the RA axis between each shot. This way no star is exactly on the same position like on the previous image. Generally my results have less background noise structures than before… And it avoids the summary of hot pixels in the stacking process. Great!
Attaching the Guide Scope and MGEN CCD Camera
I use the Manfrotto 496RC2 ball head to attach the Orion 50mm Guide Scope to the Star Adventurer. They deliver many accessories with the Guide Scope. In my setup I use the Dovetail base attached to the Adapter plate, attached to the Manfrotto RC2 plate.
