Iets uit de handleiding van de LVI SM2 om de volgende keer rekening mee te houden ;-)
” When a star has been found, the SmartGuider 2 automatically adjusts the
exposure according to the star’s brightness. The lengths of the exposure directly
affects the frequency of corrections sent to the mount: bright stars do allow for
continuous position control, which also ensures that all sorts of tracking errors,
including the component resulting from periodic error and atmospheric
18
turbulence, will be easily guided out. Bright stars are best to compensate for the
most erratic periodic errors, or with guide scopes having a focal length shorter
than that of the main optics. In this case, we advise using a moderate guiding
speed (0.15 – 0.5X) with HIGH aggressiveness (see detailed explanation below).
On the other hand, fainter stars imply a less frequent correction of tracking
errors: this makes them not as suitable for mounts with an irregular periodic error.
However, long exposure times required by faint stars could come in handy to
minimize the influence of bad seeing. Here we suggest a very low guiding speed,
best if no higher than 0.25X with MILD aggressiveness”
