If the tripod
is not properly leveled, the azimuth movement with not be level, the altitude
movement will not be plumb. And you wondered why your alignment and
GOTO are not accurate. Most of the bad alignment and GOTO are caused by
improperly leveled tripods. The built in bubble level on the Meade
883 tripod actually causes it.
While the built-in bubble level
indicates LEVEL, the tripod platform is actually NOT level
The bubble in the right picture
may be difficult to see, the bubble is at the 11 o'clock position with
the built in level centered
You should
be leveling the platform, not the the built-in bubble level indicator.
Meade 883 deluxe field tripod
Meade 884 deluxe field tripod
The bubble
level kit is perfect for ALL Meade tripods. The built-in bubble level
in the 883 tripod is useless and the 884 does not come with a bubble level.
This bubble level kit consists of 1 circular (1 3/8") bubble
level and 2 straight (1 inch) bubble levels .
"Why do I need the two straight bubble levels
", you may ask. The two straight bubble levels help you to level
the tripod faster and more precisely. The proper way to level the
tripod is to adjust only two of the three legs. You level the tripod
front to back and level the tripod left to right. One of the tripod
leg does not need be be changed. The two straight bubble level tells
you which leg to adjust. The little trick of using the two straight
bubble level is: the side the bubble stay is the side that should
be lowered. It is easier to shorten the leg than to lengthen it
because of the weight of the tripod. There is little confusion
on which leg to adjust, you adjust the NORTH leg for front to back
leveling, and adjust either the East OR West leg for left and right
leveling. If your tripod is leveled front to back and left to right,
the circular bubble level would also be centered.
You may also use the two straight bubble level to level the telescope
fork arm in the Polar position, the telescope optical tube assembly in
the Alt/Az position.
If your star alignment or GOTO is less then perfect,
this bubble level kit will give you a very portable tool to improvement
your alignment and GOTO accuracy.
