Escape from Light Pollution and Clouds - with World's lightest Travel Telescope

There is not much difference to tell to any normal fast 12” Dobsonian telescopes and you will get the same performance as in any such good
telescope dependent from the mirror quality, your observing skills and performance of your eyes and the available atmospheric seeing.

The diffraction pattern caused from the two blade secondary cage is not striking: a faint unidirectional splitted spike pattern compared to the
most common radial spike patterns caused from classic 4 or 3 arm spider mounted secondaries.

LiteScope MOUNTAIN is a very compact and hence very low standing instrument. The center of mass is to sitting considerably low so that the
structure delivers most possible stiffness for a collimation stable and vibration free observing but without the usual heavy chunky equipment.

You will find the focuser deeper for your eyes than this is usually shown in classic telescopes of comparable aperture sizes. Hence it will require a
deep observing position to sit on a small chair or on a mat on the ground, depending from the angle of altitude.

Children love LiteScope MOUNTAIN telescopes for its deep eyepiece position!

For longer observing in very low altitudes, you may choose a zenith mirror or similar optical accessory to achieve maximum observing comfort.
This will limit the maximum possible Eyepiece masses but mainly you might observe planets at such deeper positions and hence you will rather use
best suitable eyepieces for planets, which are normally lighter than those heavy 2” ultra wide angle deep sky eyepieces.
The included Sand or Plumb lead ballast plus the virtual bungee counterweight ballast for fine trim will allow you to use eyepieces about up to 900 g or so.

If you want to observe e.g. with a Paracorr Coma Corrector AND with heavy eyepieces, or if you want to use a camera, you can purchase suitable plastic
coated weight discs from us what will allow to use still heavier combinations without balance problems.
When you plan to use the LiteScope MOUNTAIN for mountain bike trips or hiking trips, it is an option to use lightweight eyepieces to minimize
packing weight.

For eyepieces up to 500g you may not need any ballast weight to counter the balance - the bungee counter system is sufficient for even Ethos Eyepiece
13 in F/3.8 when the primary mirror is a monolitical with 36mm thickness.

The single deflection bungee counter standard system (incl.) and the double deflection bungee counter system (upgrade) is for fine tuning to best
balance. Eyepiece change is not a problem and can be done without the scope loosing its position. The alitude wheel friction can be tuned.

Installation of Dob Driver, Argo Navis or the new smart Astro Fix sky locator is possible.

Deuter Aircontact Pro 70+15 for backpacking for longer trips or travels .
