In Addition the up-to-date construction of Seben Astronomy assures, that you can get a lot of accessory quickly and easily. Here is to be mentioned particularly, that all products from Seben Astronomy are outfitted with holes for 1.25 " (31.7mm) accessories.

Attention:

Please note that many Astronomy products are still outfitted with the plain and obsolete 0.98“ (24.5mm) accessory-holes. Since you can hardly get accessory for these type of holes any more, you presumably won't enjoy a product with such a characteristic for a long time. Furthermore the 1.25” (31.7mm) eyepieces, which can be used with Seben Astronomy generally, gather much more light than the smaller 0.98“ (24.5mm) eyepieces. The result is a great increase in performance.
Seben Astronomy has proven for a long time, that good quality can be achieved for reasonable prices, without making compromises with the accessory. We wish you a lot of enjoyable time with this great hobby!

Because of its up-to-date-construction and its high performance 1.25” (31.7mm) accessory-holes, you are able to equip Seben's 900mm Reflector Telescope with nearly every available accessory.
But we aren't just talking about extra accessory, we do the job properly! The following 1.25“ extra accessory is all part of our “Big-Pack“ . Whereas you usually have to spend a lot of extra money for it with other manufacturers, there is no cent to be paid extra with us.
The added 1.25“ (31.7mm) Moon Filter reduces the Moon's glare, which is produced by reflected sunlight and normally washes out most of the craters and other surface details from view.
The additionally supplied 1.25“ (31.7mm) Barlow Lens enables a doubling of the magnification of the inserted eyepiece.
The 1.25“ (31.7mm) Upside Down Lens produces an upright and side correct image. This is particularly of importance for terrestrial viewing, because usually the image would appear upside down.
Because of it's lower power the 5x24 Finder Scope makes it easier to locate celestial objects.
With the provided 1.25” (31.7mm) eyepieces (20mm, 12.5mm, 6mm and 4mm) the following magnifications can be achieved without further accessories having to be bought expensively: 45x, 77x, 90x, 144x, 150x, 225x, 300x and 450x.
The extremely stable, vertically-adjustable Tripod enables best observation conditions, especially if you want to shift from celestial to terrestrial viewing or vice versa.
Furthermore we want to accentuate the Equatorial Mount of the telescope, which enables an easier tracking of celestial objects as they move across the night sky.

Seben electronic motor drive This SPECIAL OFFER already INCLUDES this accessory !!!
|
| |
Due to the earth rotation celestial objects will drift out of the field of view without an electronic motor drive. The Seben electronic motor drive repositions your telescope automatically by exactly countering the rate of Earth’s rotation. It keeps your celestial observation target (planet, nebula, moon, etc.) in view without having to manually reposition the telescope every few seconds. Simply couple it to the polar axis of the equatorial mount and let your Seben telescope do the driving!
The Seben electronic motor drive provides sufficiently accurate tracking for piggyback and planetary (eyepiece projection) astrophotography as well as prime-focus, long-exposure astrophotography.
