In principle, the SunDancer II can be

used on any telescope that is suitable

for solar projection. When using a D-

ERF energy protection lter, catadi-

optric systems can also be used, as

well as Newtonian telescopes stopped

down to a suitable focal ratio. Make

sure that the secondary mirror does

not cause any additional obstruction

and mount the D-ERF off-centre.

The focus position when using the 2"

sleeve corresponds approximately to

that with a normal eyepiece.

On most telescopes, a star diagonal

is necessary for comfortable viewing. Mirrors are preferable to prisms, as the sunlight

does not then pass through the glass of the prism heating it up. For best quality, we

recommend Baader BBHS® star diagonals with astro-sitall mirror material (glass cera-

mic with zero expansion coef cient) and 1/10 l surface nish.

You can use both 1¼" and 2" star diagonals but it is mandatory to mount the mirror

in front of the SunDancer (i.e. between the SunDancer and the telescope's focuser).

If operating the SunDancer II from the mains, it is

recommended that the power is supplied via the

included Baader OTP II 19W: Outdoor Telescope

Power Supply 19W with right-angle plug

2457615). It supplies 12.8V at 1.5A.

If no power outlet is available, the SunDancer II

can be operated with an optional battery pack for

mobile use. The Celestron PowerTank Lithium LT

12V DC/ USB 5V/ 73,3Wh

itself. Please note the correct polarity: The positi-

ve pole is on the inside (tip positive).

Tip for experienced DIY builders: A suf ciently

strong 12V power source can, if necessary, supply

both the mount and the SunDancer II via an optional Y-cable, which makes for a very

tidy setup.

Caution:

supplied power supply or cables with reverse polarity protection. Damage

caused by reverse polarity is not covered by the warranty.
